/home Partition Is Heavily Corrupted
Jun 9, 2007So what I got is a problem that /home partition of the server is heavily corrupted.
NOC has already done a FSCK on the disk, but not all the errors were fixed. So they are
running another FSCK.
Here's what manager suggested
Quote:
Hence, to save time, we would suggest an OS reload on the server. We may do OS reload on a fresh hard disk and then attach the current disk as secondary. After that we may use a data recovery tool such DDRESCUE to recover data from the corrupted hard drive.
Since I am bit nervous now (no backups, as chornobs wasn't been able to run it due corrupted hdd for some time) wondering. How often it fails to recover all the data? I know it's hard to say, but just aprox?
Input/output Error On /home Partition On A Freebsd Server
Mar 8, 2008I'm getting the feared "input/output error" on /home partition on a freebsd server this server runs RAID-1, dmesg shows:
twed0: controller error - device failure (flags = 0x40)
g_vfs_done():twed0s1g[READ(offset=36997054464, length=16384)]error = 5
anyone knows what's my best action here? unmount /home and fsck it? or shutdown the server and replace a drive? (but, from this error message, I couldn't guess which drive is it... also, the 3dm raid monitoring didn't find any problem, so maybe it's the controller?)
Raid Disk Partition Errorc :: Warning: Invalid Flag 0x0000 Of Partition Table
Mar 16, 2008I have a disk in raid, but it seems raid is not working correctly. I took it out, and plug into another server without raid. However, fdisk shows error
Quote:
#fdisk /dev/sdb
device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
The number of cylinders for this disk is set to 20023.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
Command (m for help):
Should I correct the partition table now, or should I put it in another raid for checking?

View 1 Replies View RelatedMy Thoughts About Hacking... [Part 1]
Jul 8, 2008Is security really that critical? If so, why are some of the largest software companies providing such a bad example for the rest of the industry? Why would someone want to target my website? Why is security often overlooked?
These are all common questions that arise on a daily basis within the online industry.
The rest of this article will provide some detailed answers, along with practical examples and true scenarios.
I've spoken with numerous hackers over the past short while. I can't count the number of times I've heard the line "Ignorant site owners deserve to be hacked". In my opinion, that's like claiming that cars without alarms deserve to be stolen, or homes without alarm systems deserve to be burglarized. It's not just wrong - it's illegal.
Security risks and vulnerabilities affect the entire online industry. When a single website is hacked, there are usually multiple other victims. This is most commonly seen with widely distributed software. A potential attacker has the ability to install the software on a test environment, locate the vulnerabilities, then attack random victims even before anyone else is aware of the potential exploits. Once a vulnerability is located, the attacker simply needs to search for other environments using the same software, and within minutes there are hundreds, often thousands of potential victims.
Typically, in the race to market, software providers are encouraged to release their products as soon as the applications are usable. Critical development procedures are often overlooked or intentionally bypassed. One such miss is an application vulnerability assessment. Although the product may be usable, the effects of a vulnerable application could be severe.
Sadly, nobody is "off limits" when it comes to hacking. Most hackers feel safe committing online crime, since the online industry has evolved much faster than the security industry. Many applications are not created with the intent to recognize hacking attempts. Some hackers view their actions as a competition - Who can attack the most valuable website? Who can exploit the most user databases? In many cases, these attacks are bragged about within the hacker's immediate network. The competitive nature of these hacking groups has become so severe, there have been reports of attacks between competing organizations.
You might ask, "If I use industry standards, won't my environment be secure?". The short answer: no, but it helps. Hackers are not restricted by industry standards. Most security companies only implement new standards once at least one victim is reported. This often gives hackers plenty of time to locate other vulnerable environments, and before long, the number of victims can increase rapidly. Hackers are some of the most innovative individuals within the online industry. The most logical way to combat them is to use similar methodology for security purposes.

Part-time Sysadmin
Jun 4, 2007I am having trouble finding a good sysadmin for my needs. Has anyone else been in a similar situation? Does anyone have any advice on how to find somebody like this?
SITUATION:
I am having trouble finding a reliable RH sysadmin. I have a handful of clustered HA setups for customers (6+ servers & load-balancers) and a number of single-server dedicated hosting customers. I do a lot of the work myself. The additional sysadmin usually only has a small amount of actual worked hours per month, dependent on new installs. But, they need to be reliable, available, and familiar with the complexities of the setups.
From what I have seen, some sort of server management company wouldn't be able to be familiar with the setups well enough to not regularly make errors or modify setups correctly due to the amount of clients they have.

VolumeDrive Review Part 1 - Good Start
May 6, 2009A few people have asked me to give feedback on my experience with VolumeDrive so I decided I will be posting a 3 part review on them:
Part 1 - initial impressions
Part 2 - three month review
Part 3 - one year review (hopefully)
-------------
When I first got in contact with VD, contact was slow: about an email a day. It was very annoying to say the least. However when VD realized that I was genuinely interested in purchasing a server, and not just a window shopper, contact was more frequent and acceptable.
After looking around and comparing, I ended up ordering the following server from VD for a whopping $105 per month:
Q6600
4 GB DDR2 800 RAM
500 GB HDD
10 Mbps dedicated unmetered
5 IP addresses
Plesk 30 domain
Full managed services
Well just at face value, I don't think anyone will argue with me when I say you cannot beat the price. Where else will you find that kind of server w/ full management for $105 a month?
In the ordering process there were a few forgivable annoyances:
1) VD does not have any sort of automated, order online system for their "good" deals. I had to order via email and manually pay from PayPal. I was, however, emailed an invoice confirming my purchase after I paid.
2) It took VD 2 hours to send me my order request after I said "I am ready to purchase". Now it was late at night, so they probably only had a skeleton staff on hand, so this is understandable; however this point is sort of related to the lack of an automated system point mentioned above.
So after I paid and all, I was told they were building me a new server and it would take 3 business days to arrive. I was bummed out upon hearing this but this was understandable and justifiable - if they don't have the parts on hand, they don't have the parts, no big deal. I did appreciate the fact that they were honest with me upfront instead of trying to con me into giving me a different server (like I have been hearing stories about with other hosts).
So I waited. I was told my server would be setup on Tuesday afternoon and it was. The actual time between order and setup was about 5 and a half days: 3 days for the parts to arrive + Saturday + Sunday + time to build the server.
On Tuesday I was informed that my server has a Q8200 instead of a Q6600. To me this was not a big deal so I didn't object but if you are going to order from VD and you want one specific CPU I would be very clear with them that you won't accept any alternative. What did make me chuckle, however, is the fact that I was told "I received a free upgrade" to Q8200. It made me chuckle because I don't consider it a "free upgrade" when I was offered a choice between the Q6600 and a Q8200 for the same price during the ordering process. However, as I already said, a Q6600 or Q8200 - it does not matter to me: both are very similar in performance anyway.
So since I got my server I have been busy setting it up so VD can secure it after I am finished migrating my website (which by the way they just did - I just got an email ).
During that time I have emailed VD a fair amount of times, sometimes asking for clarification and sometimes asking for assistance with a problem, and they have responded back in a more than acceptable time frame and manner.
The only one major problem I have had so far is that initially, and by initially I mean first ~12 hours, it seems the connection to my server was not all the best. Randomly pages would take a while to load; I was curious as to why this was happening so I did some pinging and saw packets were being lost sometimes. This problem seems to have been auto-corrected itself now and I am did email VD about it; hopefully if it happens again we can get it perma-fixed.
Final verdict: people say "you get what you pay for". I say "I got more than I paid for". Hope it continues this way.
Crissic - Inexperienced And Careless Web Host: Part II
Nov 3, 2008Today I'm back to encourage you to stay away from Crissic: I know the prices are tempting, but know that you will have no one on your side when a problem comes up. I finally closed my account with them after numerous major issues with my VPS.
I've had a simultaneous account with Slicehost for the past few months, just to see if paying the extra buck is worth while. Now I know it absolutely is. I'm paying double the price for half the resources with Slicehost, but their service is amazing and reliable, their support is stellar, and peace of mind that the server will stay up and running without load issues, memory or drive failures is worth every penny. The point of this post is not Slicehost though, back to Crissic.
When I signed up for Crissic, I knew that it was a relatively new web hosting startup, but I had no idea it was a one-man show. Yes it's probably possible for a single guy to run a small web hosting company--the problem, particularly in the case of Skylar, is that when something is beyond him, it isn't getting fixed.
A recent support incident occurred where I was suddenly unable to access my VPS via SSH or the console. I contacted support, here are some of his responses to my status inquiries: ....
Offering Hosting As Part Of A Web Design Contract

Best Place To Get R1Soft
Dec 10, 2008where is the place to get backups utilizing R1Soft.
Something we are looking at and wondering as to what would be the best companie/s to have your backups at.
R1soft Backup
Aug 2, 2008R1Soft is a backup “solution” aimed at companies that want to backup only the changes that have been made since the last time a backup was created. Its a good idea, but it went horribly wrong. I am writing about it today because it was such a poor experience working with them and we had so many server problems and REPEATED DATA LOSS that I felt compelled to warn other hosting companies and customers about this extremely poor product.
R1soft caused enormous I/O load that literally killed our servers off and on multiple occasions simply would not restore our data and caused 100% data loss on the servers we had “backed up”.
MAJOR TECHNICAL DEFICIENCIES AND OPERATIONAL ISSUES WITH R1SOFT -
1) Buagent (Their software that records what has changed) is a HUGE i/o pig. It constantly blocks on I/O when there are changes causing every other drive or array in our system to lag while it catches up. R1soft told me it “works great” and to send them over details and they would “Look into it”.
2) Buserver (Their software that writes what has changed) is INCREDIBLY slow in every way that it is virtually unusable when you have a lot of data to back up with tens of thousands block changes every day per server. Clearly it hasn’t been tested well under sustained and real heavy load - at least in my opinion. There are multiple kernel and userspace methods to speed this up, but again it falls flat on its face when trying to keep up with our load.
3) Restores are buggy and VERY unreliable. We have attempted more than 20 restores (whole partitions) and had more than 30% be a complete failure, meaning TOTAL data loss. Doing user level restores were the same story - incomplete backups, unreliable and SLOW restores.
4) R1soft support is lackluster to say the least. When I complained they said, “You only opened 17 tickets in the last 60 days.” 17 tickets? Often when we had issues doing a restore or other problems we would call and get no one to answer the phone. Its comforting to know that when you can’t do a restore for 500 clients that we can possibly talk to someone on Monday who will blow us off and tell us that the newest version of the software MIGHT fix our issue. In the meantime they apologized for losing all our data over and over again. Wonderful.
5) The software is based on filesystem block changes. The problem is that the kernel and ext3 and reiser are changing all the time. As we made updates it constantly broke R1soft. When they would finally fix the problem it usually required us to reseed the entire backup again losing everything that we had previously backed up and putting enormous load on the server again while it started over from scratch
In all my years of hosting I have never had such a bad experience with a “partner” company as R1soft.
Just thought I would let other potential customers and hosting companies know my experience.
Is R1Soft CDP Backup Really Good
Jun 7, 2009I am currently moving my accounts to providers that use R1Soft as a backup solution. This is a security measure, but I am planning to use it as a marketing point too.
An after purchasing a backup account from Steadfast that includes support for R1Soft (and learning to use it), I am planning to resell their product.
Those ideas sound good, but is R1Soft software really as good as it looks like? Some years ago i had a problem with a very known (and trustable) VPS provider. After having a hard disk crash, they told that their Virtuozzo based backups weren't reliable, so I lost some data.
R1Soft In A Virtualized Environment
Mar 1, 2009Anyone have any experience using R1Soft in a virtualized environment as the VPS provider rather than the VPS user?
I'm wanting to offer some solid bare metal backup. It is generally difficult to do sound backup procedures in dom0, since can sometimes suffer file corruption when backing up running domUs from outside of them, and I use LVM drives rather than disk images.
I've always heard backing up from inside domU is best.
R1Soft is an obvious option but the pricing seems quite high and I'm wondering what kind of CPU/disk usage impact it could have. Say you just have 16 virtual servers per box (2 per core)... that is 16 instances running, and ~$2400 just in licenses alone.
Anyone have any experience doing backups/CDP in a virtualized environment? You using R1Soft or something else? Inside domU or out?
I wish R1Soft offered monthly pricing, since then the upfront investment per customer isn't nearly as much.

Oct 5, 2008what backup solution you all use. We plan on starting to use a backup solution but was wondering what the best one is. R1Soft seems to be pretty popular and I was wondering where all of you guys get your licenses from them. Also if anyone knows how much does a license for 1 backup server and 2 agent servers cost. I see it is like $500.00 at R1Soft directly but is that the only way to get it. Also is R1Soft very good? Please rate it 1 -10 in your reply.

The got all my servers set up quickly and correctly, but the most impressive thing was the communication - it is one of the best support experiences I have had in this industry. Not only on the initial set up, but even the questions i had afterward - they went above and beyond in their answers.
I know companies get ripped all the time on here for bad support - just wanted to give a little praise!
