fsck usage

[KCS_1]

Hello, all

I wonder how to check root( / ) file system by FSCK command on prompt.

If you have some tips or procedures, please let me know what they are.

Hi,

You can fsck in single user mode by booting system in single user mode and if you are not able to boot in single user mode due to corruption of / file system you can boot from recovery CD and perform fsck.

Hi,

To do a fsck you need to umount the filesystem. Since you are not able to umount the / filesystem with the server running the only way to perform a fsck of root is a reboot.
An option can be booting off a recovery cdrom, or booting in lvm maintanence mode ( hpux -lm )and do fsck on the lvol.

Get the filesystem mounted on root using bdf as,

bdf /

Find the way How to use fsck as,

fsck -V

Use the specific on that.

# fsck -F vxfs -m /dev/vg00/lvol3
vxfs fsck: sanity check: root file system OK (mounted read/write)

--> -m - sanity check
--> -p - mount informations
--> n/N or y/Y -- to use no or yes for f/s check

see more on fsck_vxfs if your / of vxfs
else corresponding fsck_fs

Hi,

it is best to check in single user mode using

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

i forgot to mention that at the command prompt you can use

fsck -F vxfs -m /dev/vg00/lvol3

(sanity check only)
