I need to run fsck.ext3 on a root partition that live in a logical volume (lvm). I know how to boot the installation CD into rescue mode, and run for example "fsck.ext3 /dev/sda2" to check a partition. But when /dev/sda2 is a logical volume I guess I first need to activate the volume before I can check it for errors. Does anyone have a link to a walkthrough on how to do this?

To display: # mke2fs -n /dev/VolGroup00/LogVolX Other thoughts: 1. Clean bit could be set - to force an fsck: # fsck -f /dev/vgname/lvolname # sync; sync (to clear buffers) then run again. # fsck 2. in emergency mode, root will mount read-only, to make read/write: # mount /dev/hdaX -o rw,remount / Good Luck!
