I have a failed system running on CentOS 6 and would like to attempt recovery of system.
One problem it has is the mdadm superblock appears to have some issues, it has all sorts of inconsistent information and appears to have been overwritten somehow. I'm getting metadata for displaying that they are version 1.0 and 1.1. I'm pretty sure all raid volumes should be using version 1.2. This happened on all hard-drives, so I can't simply just grab a working one.
I have managed to mount these volumes and copied them over another hard-drive by simply doing "cp" command with preserve permission. The new hard drive will have new UUID, so I'll have to redo some of the configuration files.
What changes that come to mind are the follow files:
- grub configuration (possible an grub-install might do the job, will need to try in out)
- Initial RAM Disk needs to be recompiled to be aware of the change
- Regenerate blkid.tab
Is there any other changes I'll need to do to make a bootable system? Thanks.
