Recovering corrupted lvol on HP-UX

Sometimes you can get the following error while try to access a directory in HP-UX:

hpuxbox@root:/root # cd /DATA

sh: /DATA: The specified directory is not valid.


This error is caused because the file system is corrupted and you need run fsck on it.

First of all, umount the FS:

hpuxbox@root:/root # umount /DATA


And them, run the fsck:

hpuxbox @root:/root # fsck -y -o full /dev/vgLOG/lvol1on clear? (ynq)y

UX:vxfs fsck: WARNING: V-3-20836: file system had I/O error(s) on meta-data.

After that, you can mount the FS again.
