fsck root file system

How to use fsck to check the / file system? Thanks.

Hi,

/ can not be unmounted so fsck has to be done while it's mounted. other options are boot in single user mode and run fsck.

best way is boot from recovery/support CD and mount old / at some othe mount point and run fsck on that.

Hi,

it is best to check in single user mode using

fsck -F vxfs -o full -y /dev/vg00/lvol3

Otherwise you can use the "-m" version

fsck -F vxfs -m /dev/vg00/lvol3 (sanity check without umount)
