Transfer files from RAID1 to RAID1

Question

RAID

There is a difficult situation.
There is a server where "rm -rf /" was executed and stopped a second after starting.
In that second the
/bin
/etc directories
have been deleted, there is no way to connect to the server via SSH, FTP or anything else. It just so happened that along the way it turned out that the server did not upload
backups to a remote FTP, but stored them in the /var/backups folder
death
outside.The server had 2 hard drives of 160gb each under RAID1 (data is mirrored)

In order to combat this situation, the hoster connected another similar server, installed the same OS (Debian 6) there, it has its own RAID1 and one of the disks of the first server is connected (because it cannot be turned off, only 1 disk was removed)
Disk It is perfectly visible from the ROM configurator:

But I will not risk creating RAID0, which means losing all the data.

Disk list: fdisk What I want to do: transfer backup files to my computer/remote ftp/additional server Trying to mount from under Debian 6 did not lead to anything How can I solve this problem?

Answer 1

With mount -t ext3 /dev/cciss/c0d0p2 /mnt/drive you are trying to mount an extended partition. It's as useless as smoking corn.
First, try to mount a normal partition:
mount -t ext3 /dev/cciss/c0d0p1 /mnt/drive
If this does not work, then most likely the point is that the raid controller adds its service information to the beginning of the disk. To get around this, you need to try to mount the partition starting at an offset of 16 (32,64,128, etc.) bytes.

Answer 2

What were you trying to achieve by mounting the second partition? Which data cannot contain at all, tk. extended?
You need the first one.

Answer 3

Ok, we figured out the sections. This is not the same array.
Look for your third disc. I'm not familiar with HP raids, so I can't tell you.
Look for the definition of disks in the dmesg output, in /dev/sd* and /dev/hd*
If not, go to the raid configurator, look for the option to connect a disk without a raid

Answer 4

Put two disks in the mirror and try to dd the partition where the data is located, or try copying from a working one via nc over the network, if it remains. SmartArray is very capricious, and nothing can be copied through the HBA.
