I have a server with CentOS Enterpise 4.6 using 2.6.9-67ELsmp Kernel
I found that I must update the kernel for security reasons !! so I updated it to 2.6.25.3 ( leatest stable version )
I updated it 2 times but always fail in this server
As I have never used cPanel neither have whatsoever experience with control panels, in the process of ordering a couple of new server I am wondering what's the average recovery time after a server failure which involves data (ie. disk failure).
I am interested to understand this, because I need to choose between hardware raid or backup disk.
For example, at LiquidWeb (this is just one of the many managed providers i am evaluating) you can pay the same server 264$ with 2x250 hardware raid 1, and 219$ with 2x250 simple hard drives, where the second one is supposed to be a backup drive.
I am yet to ask, but on this servers most likely (at this prices) they do not have hot swappable disk drives where they can rebuild the array "live", so also if i choose raid hardware, in case of a disk failure, i face a downtime to bring down the server, rebuild the array, bring on the server, which I guess is something not less than 30-60 minutes downtime.
The advantage of this solution is that a disk failure keeps the system running, so you can schedule a maintenance window to replace the disk and rebuild the array, I guess.
On the other side, relying on a backup disk (and of course rsyncing data to an offsite server, i would do this anyway) you save 45$ each month, and disks after all do not fail every month.
If the main disk fails, they need to replace the disk, install again the server with what I suppose being a standard image (so let's figure a couple of hours, as they have a 30min hardware replacement sla), then you need to restore backups (which in my case are something like 20gigs). So I guess, on an average, it would take something like 4 hours downtime.
Am I correct ?
What would you reccomend as a solution with cpanel, taking into account the huge price difference ? Backup drive or Hardware raid ?
This would be for a single big website, not a hosting-company with resellers and customers environment, so I would value more the monthly saving, rather than the high availability, but of course I am interested to know what is the average time to recover a cpanel server after a drive failure.
Besides I have also another question, as I have never had a colocated server with raid hardware, so i do not know anything about this.
When a drive fails in a raid1 hardware environment, how the hosting provider gets notified ? I suppose it's not a led on the server to blink, as no one would see it.
So if you have software raid (like my computer at home) you get an email from mdadm with "warning, array degraded", so you know it quick and you can check it anytime doing a ' cat /proc/mdstat '. What about hardware raid?
My fear is that nobody notices my raid1 drive failure, the server keeps going on just a drive, then maybe the other drive fails, and it would be unpleasant: while a single drive failure would be obviously very easy to spot for me.
Just wondering for anyone whos done a kernel compile on an Atom based machine, how long did it take?

I always seem to be getting these errors only for Cpanel VPS only.
kernel: TCP: time wait bucket table overflow
kernel: TCP: too many of orphaned sockets (90 in CT****)
Even Cpanel Install by SSH or VePortal gives the same error.
we have one box in hivelocity.net that has been down so many times this month that we were forced to remove links to siteuptime where we were once so proud of having a 99.7% uptime for 3 years in theplanet.
syslog shows that just before crashing, these entries were made:
kernel: kernel BUG at mm/rmap.c:479
kernel: invalid operand:0000 [#1]
dmesg also shows this:
...
Brought up 2 CPUs

checking if image is initramfs... it is

mtrr: your CPUs had inconsistent fixed MTRR settings
mtrr: probably your BIOS does not setup all CPUs.

...
i've googled these messages and they point to ram problems.
hivelocity.net claims to have done diagnostics on the box and that there were no problems reported.
they said this is a result of a sys configuration problem made by us.
any ideas?
running centos/virtuozzo 2.6.18-028stab062.3
when i configure vmware it asks at one point for kernel header files. where would i find them to match the current kernel?
i asked at parallels forums but help there is very scarce. i checked openVZ repositories and they dont yet have headers for this version.
what are my options? i have one last windows machine left and want to run it in VMware.
Last year I ordered a new server with Centos 4.3 and it had the kernel kernel 2.6.9-34.0.2ELsmp installed. It runned fine and I didn't update any packages since then.
Today I started getting a problem where both mysqld and kswapd0 uses very high amounts of CPU, spiking up to 100% and my memory usage is at 99% all the time. The problem seems exactly the same as the one mentioned in this thread.
In that thread the exact same kernel is said to be insecure and to cause this problem. I also came across a centOS bug that reports this problem with high cpu, mem usage and mysql & kswapd0 consuming all resources.
In the linked thread the person solved the problem by upgrading to kernel 2.6.9-42 using rpms but others recommended a newer kernel or a custom compiled kernel for CentOS.
Apparently when they used yum it said 34.0.2 was the latest kernel.
What should I do to upgrade the kernel, which version should i upgrade to, and where do I get it from? I won't be able to compile a custom kernel and I've only installed basic rpm packages before.
This is a rare issue i have on a RHEL 5.2 + cPanel server.
Server time is:
Tue Nov 11 17:02:51 CST 2008
Squirrelmail time show:
Code:
Last Refresh:
Tue, 5:02 pm
So, that is correct too..
But email arrives with -4 hours time, example:
webmaster@xxx.com 1:03 pm testing email
I already rebooted httpd, exim, and imap server, and the server itself too.. and problem stills.
I got report from webceo that I have some issues. May someone help me fix this?
DNS Lookup: 0.22 sec
Connect time: 0.33 sec
Host ping: 0.10 sec
That mean too slow with the other sites!
I can't get access to a certain site. I always get the page with:
network time out - server at *** takes to long to respons. More people have noticed this and apparently it only happens to people with certain specific providers. And not all the time. Some times they DO get access eventy to they belong to the same ISP. So I guess an ISP isn't blocking access to it otherwise it would be permenantly/The site administrator insists that certain ISP's are blocking his site. He's hosting it on his own server. The domain belongs is registered at namecheap.com.
If an ISP is blocking this site (if that's possible?), that would lead to that 'network timeout' page wouldn't it?
What is the most likely reason for getting a timeout page anyway?
I have a dedicated server specs: AMD 3500+ 64 Bit CPU, 1 GB Ram, 160 GB Sata Drive. For 1 month, CPU load average reaches 40-50 value. This happens about 5-6 times in a day. When I stop httpd service for 30 seconds everything goes normal. I think this is not a DoS attack because it comes systematic, I dont believe no one makes this regularly except bots.
Maybe its a system service or a cronjob but it stops when I turn off httpd service?
How can I be sure about what's making this regularly load?
I also did set up a script which mail me when load average of system goes crazy and restart httpd service. But instant restart is not working to stop load increase.
The server is going down from time to time, every 12 days or so the site hosted there is no longer accesible, everything starts with the site slowing don and down and then is not longer reachable, what we do is to request a power cycle, and with this we start all over again till next power cycle, so on so on, of course, here are my server details and more info on this:
- MySQL - 5.1.41-3ubuntu12.10
- Apache - 2.2.14-5ubuntu8.4
- PHP - 5.3.2-1ubuntu4.9
- operating system: Ubuntu Server 10.04 LTS
After some time emailing the support guys to barely check about what's going on, we received an email with a few things:
1.- found a few errors that likely would cause issues with Apache. The first error is:
[Mon Feb 04 05:03:10 2013] [error] mod_fcgid: fcgid process manager died, restarting the server and the next error is:
[Mon Feb 04 14:32:34 2013] [error] server reached MaxClients setting, consider raising the MaxClients setting ...
Both these errors seem to indicate that you have a process that is running out of control on your server. We were unable to determine what script on your site is running caused your connections to be maxed out however it does appear that before these errors were generated there was a WordPress plugin referenced in your access logs...
2.- Additionally during our review we did find that your error log for mercadodedinerousa.com is 45 GB's which is excessively large and can cause problems when Apache is trying to write a such a large file.
3.- The majority of the errors being logged are:
[Wed Feb 06 12:12:31 2013] [error] [client 200.76.90.5] Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden: /var/www/vhosts/mercadodedinerousa.com/httpdocs/index.pl, referer: [URL]

I was hosted with these guys for well over 2 years, and was spending on average more than $2,000.00 a month for servers.
I had slowly grown to well over 10 boxes, and was definately on my way. then one day I get a spam complaint that one of my serves was casing complaints. So I checked it out, and asked for the complaints to be relayed so I would have record of it..... nothing.... I responded and even tried to call, but at that point they had sent me a tciket stating.
We have recieved well ofer 1000 spam complaints from a server you lease with us, per out TOS we are terminating ALL OF YOUR SERVERS, and you have 15 days to remove the data!
WOW... there was no ability to have them terminate that server, they simply said NO your account will be terminated (all of your servers) and you will be banned from The Planet!
When I tried to call they said your not allowed to speak with the abuse dept, again I tried contacting my account manager, and he said he checked into it and only saw a few complaints, and didn;t understand why they were doing this... In short I barely got moved over to another provideer before they shut me down completely..... They did however offer one course of action... you could turn your dedicated server clients over to us so they dont have to move! THEY ACTUALLY SAID THIS!
I at that point made the move and then they hit my credit card for another month well short of 20 days before a bill would even be due.. I had to file charges at the local courthouse to get this reversed.
My advice, if you host at the planet dont send mail. get another server provider for mail, these guys are *&^)(* and they don;t care about shutting you down no matter what you spend with them, on top of that they will try to scarf your clients up if they can, after they leave you high and dry....
Anyone else have issues like this with anyone else. I want to compile a list of providers that do business like this so I can avoid them.
Probably nothing new. Seriously, they're horrible and everyone here probably knows it. But... I'm ticked, so I'll add something extra to show how genius they are.
The problem is I can't seem to reach my website on godaddy. It appears as if the server is down. Both via the browser and ftp it fails.
Anyway, I could write a review but no need... I'll let the e-mail I sent them and their responses do the talking.
Okay, thanks for the information... I'm still humored that needing my pin is
actual security considering it's listed on your website after I login. My
password is way better security because it's never visible anywhere...
anyway... based on the information you gave me here's what I have found out..
The first instance of me not being able to reach the website was around noon
EST yesterday. Earlier that morning I was on the website and had logged in
via FTP. After noon the website was no longer reachable. This is a test from
one computer.
Around 6PM on a different network, the website was reachable from 3
different computers, including the one it wasn't reachable from earlier that
day. About 30 minutes later the website became unreachable again. Attempts
to reach it from all 3 machines failed.
This morning, I considered your response email and assuming the webserver is
up like you stated, I decided to try another network. The website was up on
that network. However, it is still down on the other two networks. It seems
that the website works for a limited time on each network before something
happens to keep the network from reaching the webserver.
Attempts at pinging the webserver all fail.
Doing a tracert to 2leet.com times out at the following: ....
so my server dies every day and requires human intervention to fully restart all service to have my site work properly. i suspect sigterm issues as it fails to restart all service as website is still down so i always have to reboot it.
Tried recompile apache with no success

Some of your MX do not work properly
just a 4 drive raid 5 array go down, this is hardware based, controller indicates a 2 drive failure.
It is possible to rebuild this array from the 2 good drives?
Thing is that drives come up fine in test system when testing in spinrite which show no problems, though only 2 show partition structure others just come up as empty!
I have had sporadic mysql failures. Cpanel/WHM successfully restarts it and I am notified via e-mail and text message, but I have yet to be able to determine what is causing the failure. From what I can tell nothing is logged ether by cpanal, mysql or the system about the failure.
My questions is can cpanel or mysql be configured to log what the issue is?
I have the max connections for mysql and apached limited to match the servers capacity.
I had a server built and it is now at the data center. It is working great.
I have a Raid 10 question concerning what would happen if one of my hard drives failed.
I have a 3ware 9550SX card. If one of my drives fails and I install a new one with it automatically rebuild on it own?
Someone I know mentioned to me that I need IPMI, KVM override B for it to do this and that I would also have to have software installed fore this to work.

Anyway ticket has been issued to them and still waiting for reply.
Just curious if anybody else face the same problems as i didn't not play around with my DNS servers at all.
I am writing this message to share with fellow readers my sincere dissatisfaction and utter disappointment with the low standards and non-performance of customer service at 1&1.com. The following message is a copy of a feedback e-mail that I sent to 1&1 management after cancelling my Dedicated Server. I was a customer since 2005.
----
Dear Sir or Madam:
I am writing to provide you with feedback on my experience with 1&1, and the events and circumstances that led me to cancel my Dedicated Server Package (a "1&1 Managed Server III"). I have been a customer since 2005, and over the course of these past few years, have witnessed the gradual degradation of service, transparency, and accountability by 1&1 customer service and technical support staff.
I purchased a Managed Server because I wanted support personnel to administer my system, so that my business team and I could focus on building and developing content. We design and launch web sites and interactive communities focused around creative topics, and our sites are ultimately very successful and highly active. Upgrades of our server's operating system were often done reactively and late, rather than proactively and positively, at times exposing our server to security holes and performance inefficiencies. However, my real disappointment rests with how your customer service has been managed.
Over the past year, there were complete server outages that lasted several hours at a stretch. When I was aware of these, I would call the 1&1 Customer Service line, via the "dedicated server" 1-800 number that your company had established. What I received was an outsourced call center in India, with absolutely no ability to perform technical or quality maintenance on my server. The customer service representatives were marginally understandable through their thick accents, and were very clearly reading from a script. Their inability to think creatively and adapt solutions to the problems at hand is understandable, even if frustrating; but entirely unacceptable is the fact that, by their own admission on several calls over the past few months, the data center in the United States was unstaffed. Ordinarily, Tier-1 customer service escalates to live Tier-2 and Tier-3 technicians and admins; your customer service department, however, was left lodging help desk tickets into a system that, according to them, would not be checked in days.
In the latest episode, my dedicated server went offline on Friday night. Saturday morning, I was on the phone with your customer service personnel, who told me that the U.S. data center where my server was located was unstaffed on weekends and admins might not be able to get to my issue until Monday morning. They repeatedly offered insulting "scripted" suggestions as to why my server was offline ("perhaps it was my Internet Service Provider?", for example). Finally, they concluded that there was nothing that they could do - not even a remote-reboot, which is now standard in the industry (such as an APC-reboot). All in all, my server was offline for over 20 hours without explanation, with no clear accountability, and with zero communication. When I kept calling, demanding escalation, I finally got through to an admin in the United States, who managed to remote-force-reboot my machine. After I conversed with him briefly, he simply said he did not know why my server went offline.
Our Dedicated Server's system specifications were modest, but still competitive (a Pentium 4, 2 Gigs of RAM machine, with around 500 concurrent MySQL connections on a single site). Our site's system specifications, using out-of-the-box software that we licensed to run our site, should easily have supported thousands of concurrent connections before we needed to upgrade our system. Nevertheless, I specifically paid extra and purchased 1&1's "managed dedicated server" option because I wanted the extra care and attention to our business-critical web sites.
FEEDBACK ITEMS:
To improve upon your business, I recommend three immediate changes.
1. Train Your Customer Service Personnel.
Your Indian/Outsourced customer service appeared generally unfamiliar with both my package (they had to escalate several times, placing me on hold for over 20 minutes at a stretch, before they could conclude that I had a dedicated and managed server), and had been reading from an outdated script that left them uninformed and incompetent to handle even basic queries on system status, server and service readiness, and the functionality of my server. Furthermore, they were completely unsupported by not having any live technical team working during reasonable hours.
2. Staff your U.S. Data Center.
It is astonishing, and horrifying, to me that 1&1 is apparently selling any hosting services, much less dedicated/managed hosting services, on a data center that is apparently not staffed with technicians 24 hours a day, 7 days a week. In my situation, my business-critical server went offline for nearly 24 hours, and there was no one that either I, or your Outsourced/Indian Tier-1 customer support could escalate to in order to get accountability. Furthermore, there was no transparency: there is no number to reach a live human being on-site at the data center, and your Customer Service personnel seemed either unable or unwilling to ask questions to figure out if anyone was in charge on the ground. They concluded to me, on the phone, that the "technicians were home for the weekend". That is entirely unacceptable, and it operates on a level of non-performance that is shocking to me as both a business executive and an organizational manager.
3. Provide full-time, English-speaking, U.S.-based Customer Service.
Your call center in India was staffed with people who, quite frankly, were neither qualified nor competent to handle the concerns of your United States and European customers. When asked questions that deviated from the script that they were reading (you could hear them both typing and flipping pages to try and find the answer), they ended up placing me on hold for long stretches of time. There is zero innovation, and absolutely no adaptability by your customer service at this call center. When this scenario unfolds, there absolutely must be an immediate, Tier-2 customer service personnel that can promptly, professionally, and courteously handle the concerns of your customers, and they should do so in an intelligent, dynamic, innovative fashion. I am extremely patient and forgiving of outsourced and offshore technical solutions, especially since my business leverages a global model similar to most information technology consultancies. I can only imagine the number of clients that your user-unfriendly, backward, and mentally-atrophied customer representatives have cost you. The fact that they are the only customer support you offer before escalation to a (non-existent or absent) technical team is unacceptable, and speaks of a systematic failure in your organizational management and escalation hierarchy structure. Please, for the sake of your future customers, provide a full-time, intelligent, responsive, and communicative U.S.-based customer service team.
CONCLUSION
In closing, I want to reiterate my sadness at having come to the decision to cancel my 1&1 account and close all of my business with your organization. I have been a customer for nearly three years with your company, and have been very patient and understanding of the delays and mismanagement with customer service, especially since it seemed that in previous years, you had an attentive and present technical support team that would resolve matters promptly. However, after the past few months, I have witnessed the apparent absence of any service level agreement to respond to issues, queries, or escalations, the complete incompetence and mismanagement at your outsourced and offshore Indian call-center, and gross non-performance of your technical personnel and utter negligence of your support staff on the data center. Within a matter of moments, I was able to identify a major and large-scale competitor of yours that offered me an enterprise server solution at a U.S.-based data center that was staffed 24 hours a day, 7 days a week; a full-time U.S.-based customer service team that had guaranteed SLA's of responsiveness; and, professional management services for a comprehensive management solution -- all of this at a cost less than what you currently charge new customers.
The decision was one of the easiest ones I have ever made.
I am getting this error on my mail from cpanel

Is it a big issue.. whats the solution for it?
so this is the second time I got an email like this from my server:
This email was generated by the smartd daemon running on:
host name: xxxxxxxxxxxxxxxxxxxx
DNS domain: xxxxxxxxxxxxxxxxxxx
NIS domain: (none)
The following warning/error was logged by the smartd daemon:
Device: /dev/sdb, 6 Offline uncorrectable sectors
For details see host's SYSLOG (default: /var/log/messages).
You can also use the smartctl utility for further investigation.
No additional email messages about this problem will be sent.
What can I do about this?
I actually COLO a box.. I sent them the server NEW, and the drive failed a week after I sent them a new one. This SECOND drive is now having errors apparently.. what can I tell my tech to do about this? Please advise me on what I can do.. (There is a chance that this could be my primary drive)
I asked FDC to check the controller and drive, and they said there was nothing they could do.
Let me start by saying that we use redundant power supplies for all of our core service nodes, however I am wondering about the failure rate others have experienced.
I have been in the industry for nearly 4 years now, and have yet to see a power supply failure, so I'm considering just going with single power supplies instead of redundant.
