Problem description:
Ubuntu Server 12.04 LTS
My HDD is using RAID-1 isw, message shows sign of breaking so decide to do a swap.
Swap the first drive, reboot, change the isw_xxxxxxx in fstab,
Code:
sudo dmraid -R isw_xxxxxxx
wait for the sync to complete, reboot, see system booting normally.
Shutdown, swap the second drive, drops me to ramfs and do dmraid -r isw_xxxxxxx, wait for the process to complete, lvm can't find any group.
reboot, says system can't find OS, the whole partition is deleted.
really frustrating.
Could anyone help on this? Thanks.
