Move os from 1 disk to the other


I have server with 2 active disk, but disk 1 contain big part of os is falling,

how can i move everything to disk 2 and then remove the disk 1?

# 2  
If your disk2 is empty, you will need to create a RAID mirror configuration from disk1 and disk2.
If everything goes ok, you will remove the disk1 from mirror configuration and replace the faulty drive and then re-add it to existing mirror.

Depending on your OS and hardware (do you have RAID controller ?) commands will be differenet.

No offense intended, but that you have to ask strongly indicates you should not attempt this migration yourself (unless it's a non-critical or personal system that can be sacrificed at the altar of education).

Aside from moving files, bootloaders may need reinstalling and system files which reference partitions may need updating (e.g. /etc/fstab). The exact procedure is system dependent.

alister is correct: if this system is of any value you shouldn't attempt to solve the problem but get some professional help for that.

Having said this: which system do you have (OS?, hardware?) and how is it configured (LVM used?, etc.)

Without this information your question is like asking for the solution of the math problem in front of you without telling us what the problem is. We simply can't tell.
