One Hdd Failure On RAID5
Oct 19, 2007How long it takes to rebuild RAID5 if one of failed disks was replaced? How long it takes to assume full performance again?
Our support changed disk in our server 2h ago, but it's still extremely slow

Copy Files From Raid5's HD To Raid5's HD
Jul 21, 2009i use Adaptec 2200s with three scsi HD to do raid,
it is install centos with cpanel.
after rebooting,it can not load into the raid5 well,
and shows no logical drivers... and no operation system found.
i try to add new hd,but it still do not build and run.
i think it may the raid5 configuation on the three HDs are missing are ger problem or it will not work at all.
i want to ask,if a use another three hds with the Adaptec 2200s to set another raid5.
and build another one server.
and i mount the old first one HD from the old raid5 and mount the new first one HD from the new raid5,
and copy the files from old ones to the new ones.
Raid5
Mar 1, 2007Now I'm a little new to RAID5, I've always used RAID10 or RAID1, but I am looking into RAID5 for my new server.
Tell me which you think would be more beneficial, I know RAID10 is faster for writing and copying which is what is needed for SWAP but I also know that RAM is a lot faster than SWAP.
8GB RAM
2GB SWAP Partition
4x250GB RAID5
7GB RAM
3GB SWAP Partition
6x250GB RAID10
or
8GB RAM
2GB SWAP Partition
3x400GB RAID5
Is 3 drives or 4 drives faster in a RAID5? I know 4 drives would probably read faster but would copying and writing be slower?
Raid5 Module In 2.6.18
Mar 22, 2007I am trying to configure a 2.6.18 kernel and I cannot get it to read the raid5 module since my system is utilizing a software RAID5.
Whenever I build I receive the following error:
[root@localhost linux-2.6.18.8]# make install
sh /root/kernel/linux-2.6.18.8/arch/x86_64/boot/install.sh 2.6.18 arch/x86_64/boot/bzImage System.map "/boot"
WARNING: No module raid5 found for kernel 2.6.18, continuing anyway
I have tried versions 2.6.18 and 2.6.18.8 and both give me the same issue.
I have CONFIG_MD_RAID456=m in my .config so the module should be getting configured.
I tried ignoring the warning but when I boot up my system in 2.6.18 I get a kernel panic error, could not sync. (I'm guessing because it doesn't have the RAID module). Everything works fine when I boot up in the 2.6.9 CentOS kernel.
RAID1 Or RAID5? Which Is Best
Jul 30, 2008What do you feel is better for a typical shared/reseller hosting server?
RAID 1 or RAID 5 (with three drives)?
PDSME+ Bad Performance With RAID5
Jun 10, 2008I have a problem with performance on my server.
My server is with Supermicro PDSME+ and 3x500 GB WD Raid Edition with one hot-spare.
When I migrated from RAID-1 to RAID-5 the performance droped dramatically. I have been reading different posts on internet that suggest to force HDD to work on 1.5 GB/s. On Supermicro support page there is a similar issue and support staff explain that ICH7R do not support SATA-II.
When I review specification on their web site, they typed that MB support 3.0 GB/s.
Does anyone have a similar server with a similar issue?
RAID0, RAID1, RAID5
May 30, 2008Which to choose? RAID0, RAID1 or RAID5?
how can explain what is the best one and why?
Identical Mirror/Mirroring Servers Vs. RAID5 NAS
Nov 16, 2006We are expanding our photo sharing business and are revising our Unix-based server architecture. We're looking to develop a standard server configuration so that we can easily add servers when necessary.
Our ISP has recommended a configuration with mirrored web servers and mirrored RAID5 NAS boxes. I've read about Google's server architecture which consists of identical mirrored servers; when a drive or part from one of those servers goes down, data is served from the mirrored servers and the bad machine is repaired or replaced.
Comparing the two architectures with similar storage sizes, the overall cost of the hardware itself is about the same, with the identical mirrored machines being slightly cheaper. The monthly co-location fees (rack, power, etc.) are higher for the NAS solution.
I'm interested to hear your thoughts and experiences with similar solutions. I know the web/NAS solution is popular, and it's probably the one we'll go with, initially at least. Has anyone here implemented a Google-like identical mirrored server solution?
Software RAID5 Not Booting Up Without All Hard Drives
May 14, 2007I setup a Software RAID5 the following way:
/dev/sda:
1: /boot 101MB
2: software raid ALL
/dev/sdb
1: software raid ALL
/dev/sdc
1: software raid ALL
/dev/sdd
1: software raid ALL
/dev/md0: ext3 mounted as / for all of the software RAID partitions.
I was left to believe this would create redundancy as long as only one drive is removed from the array. Although when I unplug any of the hard drives (one at a time) I get input/output errors and when I try to reboot I get kernel sync errors.
What exactly am I doing wrong when trying to create redundancy? I know that SDA contains the /boot/ partition so it wouldn't boot without that but even if I unplug B,C, and D it still can't sync.

The Planet Failure
Apr 28, 2009I 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.
Godaddy = Failure
Nov 4, 2009Probably 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: ....
Reboot Failure
Mar 18, 2008so 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.

Raid 5 Failure
Nov 7, 2007just 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!
Mysql Failure
Jan 23, 2008I 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.
Raid 10 Failure
Apr 4, 2007I 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.

1&1.com - Failure In Customer Service
Apr 2, 2008I 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.
Possible Hard Drive Failure
Jan 12, 2008I am getting this error on my mail from cpanel
S.M.A.R.T Errors on /dev/sda
From Command: /usr/sbin/smartctl -q errorsonly -H -l selftest -l error /dev/sda
Please note the following marginal Attributes:

----END /dev/sda--
Is it a big issue.. whats the solution for it?
Upcoming Drive Failure
Sep 6, 2008so 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.
Power Supplies Failure
Dec 1, 2007Let 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.
Dns Report Shows Failure
Jun 5, 2007My VPS is setup and now when I did a dnsreport for my site, it shows:
Number of nameservers
ERROR: You have 2 nameservers, but both are on the same IP! This is not a valid setup. You are required to have at least 2 nameservers, per RFC 1035 section 2.2.
Is this a big problem?
The report [url] also shows other failures. Are there any critical ones that I need to take care of? How do I do it?
Hard Drive Failure. Now What
Aug 3, 2007I'm currently hosted on a VPS server with Galaxy Solutions, but just last night I was informed of a hard drive failure.
This morning they said the DC couldn't recover the data, and now they are trying to recover the data themselves. Right now I'm assuming that if the DC can't recover it, then there isn't much of a chance of it being recovered at all.
I've put in countless hours and dedicated so much of my time to my sites, something which certainly cannot be compensated for. I would like to exhaust any possible way to recover the data.
Can anyone recommend what I should do in a situation like this? Would it be advisable to consult a data recovery specialist? It would be great if you could also recommend one.
The cost doesn't matter. I'm extremely frustrated, annoyed, and confused because of all this. Just like that, all my work is gone.
I did have backups, but they were on the same server.

Qmail Sendmail Failure
Jul 2, 2007I have a weird Issue with my Qmail program. It happened when I separated webmaster@domain, postmaster@domain, and admin@domain into separate e-mail accounts, instead of having them as aliases of each other. Now the standard server and anti-virus automated e-mails all get bounced, and the bounce messages are overwhelming my admin account.
Also randomly some important messages from approved senders also get bounced and end up in there, but with the sheer quantity of messages (100s per day) I have no way of going through and filtering them out. All spam get's failure notice's, but that's how it should be.
I'm a web designer, not a webmaster, but I ended up in charge of this and can't figure out how to fix it. Some insight into the possible cause would be much appreciated.
Here's a sample e-mail:
