Rsync Failed On Me..couldn't Recover The Data
Apr 14, 2007
I am putting this thread to take other people advise and to advise them about my bad experience with rsync. Lucky, I was able to get my data back through the old drive
Three times a day, I take mysqldump and then rsync that mysql dump to a drive located in a different state.
Everything was working fine..The rsync was transferring data daily and updating the backup on other server. Few days ago, there was a hard drive failure on my server and then i checked in my backup drive for mysql dump...It was 764 bytes instead of 5 Gb...
Then i went to my other server where I rsync, to my surprise that was also 764 bytes from 5 Gb as it synced the both database..
My backup strategy failed and would be in tears if I couldn't grap data from failed drive
I would like to hear everyone views on this and learn from it

I have 100+ sites on this hard drive, and one site in particular that meant the world to me.
My host sent the drive to Gillware first, but they failed saying that the file system was so severely damaged that they could not recover anything.
Then shortly after, my host sent it to DriveSavers, a very well-known company, but they also FAILED.
I'm extremely depressed because of this. Please don't post if you're going to say "make sure you do backups next time" because I've heard it 504329504395 times now, and while I do realize my mistake, saying that does NOT help me.
I am willing to spend ALOT to get my sites back. I still have hope. Are there any other companies out there BETTER than DriveSavers? Assuming that you'd still have hope even after two companies failed, where you would you go or what would you do?

I have a crashed HD that I want to recover the data. I wonder if there is any method or software out there that can do this for me.
The hard drive is installed with centos and uses ext3 filesystem.
I have tried doing a mount, not if it is done correctly, but I only see "lost+found" on the hard drive.
Usually when this happens on my hard drive w/ windows, I use some data recovery software to extract the data. I don't know which software will do this for me on an ext3 filesystem running centos.

I just recently had a hard drive failure that produced the following error
root@re:/# mount /dev/hda3 /mnt
mount: wrong fs type, bad option, bad superblock on /dev/hda3,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
ide: failed opcode was: unknown
end_request: I/O error, dev hda, sector 4410069
Buffer I/O error on device hda3, logical block 8259
hda: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
hda: drive_cmd: error=0x04 { DriveStatusError }
ide: failed opcode was: 0xb0
The host is going to mount this HD on the same machine after adding a new hard drive and fresh install... Does anyone have any recommendations for how I can go about recovering data? Specifically mysql databases?

Windows Application 2003 crashed on RAID 5 server, we tried to take the NTFS files from the hardrive and mount them on a knobix which was booted from a cdrom drive. Knopix could read the files but it was unable to mount them I guess for compatiblity reasons.
Is there anyway we can get a backup of that ntfs file and restore our data?

Trying to figure out rsync and am a little confused. Here is what I am trying to accomplish (usernames, passwords, and Ip's changed to protect the innocent):
ServerA = Live production server
ServerA Username = rootA
ServerA Password = passwordA
ServerA IP = 123.111.222.AAA
Directories from ServerA to backup: /usr/home/www and /var/lib/mysql
ServerB = Backup server
ServerB Username = rootB
ServerB Password = passwordB
ServerB IP = 123.111.222.BBB
Location on ServerB where backups will be located: /usr/BACKUPS
rsync is located on ServerB at /usr/bin/rsync
I want to use ServerB to pull the data from ServerA to ServerB. I want to maintain all permissions, ownerships, etc. I will be putting this in a cronjob to run every 48hours. After the rsync is done, I would like to see the following on ServerB:
/usr/BACKUPS/www
/usr/BACKUPS/mysql
Is this possible? And if so, what command usage would I use? And how would the password get passed?

I found a problem with the scheduled rysnc ...
I tried also to run it manually but there is an error.Command:
#rsync -avz --exclude=/proc --exclude=/backup -e ssh / user@user.bqbackup.comerver1
The error:
building file list ... rsync: writefd_unbuffered failed to write 4092 bytes: phase "send_file_entry" [sender]: Broken pipe (32)
multiplexing overflow 1:1075
rsync error: error in rsync protocol data stream (code 12) at io.c(681)
What should that be ? I didn't change anything in my server ...

My host just recently sent the hard drive with my sites to a data recovery company called Gillware. Website is [url]- but they failed and gave the following reason:

Gillware Inc.
Do you guys think there's still hope?
The hard drive is now being shipped to a more well known company, Drive Savers - [url]and I'm guessing that this is the last hope, because the more the drive gets tampered with, the more chance of permanent data loss.
So yeah.. I was just wondering what you think? If the file system is so severely damaged, do you think it STILL can be recovered?

We just upgraded our server with 8 brand new seagate cheetah 15k.5's, a battery backup unit, and a 256mb dimm for the raid controller. In the boot process, i noticed an error about caching or something.
After analyzing the dmesg log, i found the error:
sda: asking for cache data failed
sda: assuming drive cache: write through
It seems like the kernel can't get to the raid controllers cache, so it switches to the write through setting.
I've benchmarked the harddisks with the write through, and write back setting. The odd thing is that both settings deliver the same performance.
Normally, write back increases the performance with like 100%... That's why we bought the battery backup unit.
So something is going wrong, but where lays the problem?
Server:
Quote:
8 X seagate cheetah 15k.5, U320, 16mb cache, SCA, 73GB
1 X chenbro backplane, U320, SCA, 2 channels, 8 ports
1 X LSI megaraid 320-2x raid controller, U320, 2 channels, battery pack and 256 upgraded dimm
6 GB DDR PC3200, ECC, CL3
2 X AMD opteron dual cores (4 X 2.0 ghz)

My server HDD got corrupted. My server provider mount a new HDD for me, and put the OLD HDD as secondary drive.
This is what they emailed me:
[root@ns1 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/hda3 149G 3.7G 138G 3% /
/dev/hda1 99M 17M 77M 19% /boot
none 498M 0 498M 0% /dev/shm
/usr/tmpDSK 485M 13M 447M 3% /tmp
/tmp 485M 13M 447M 3% /var/tmp
/dev/hdc3 149G 23G 119G 16% /backup
I have a forum data (files and database) that is still on the old HDD, I hope to retrieve it.
May I know how can I access to the data?
I tried SSH, can only go till /dev/, then don't know what to do.
What is the command in SSH that I should type in order to go to the 2nd HDD? How can I retrieve the database and files to my new HDD?

I've already changed a lot of MX records but never run into a problem like this one ...
I google it and found out that this might be cPanel/WHM bug. I've mailed them but they need a lot of time before they reply so I will also ask here
Here is error log from WHM:
Setting mx priority 10 (mx1.domain.com)........failed: Error fetching zone data for otherdomain.com.db's MX ...Done
Setting mx priority 20 (mx2.domain.com)........failed: Error fetching zone data for otherdomain.com.db's MX ...Done

I just discovered there is seperate error log for php-fpm and since only 1 site is running fully nginx, the log is full with this error:
"NOTICE: PHP message: PHP Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/lib/php/session) in Unknown on line 0"
I've checked and the path is correct....
