Dear all

I am new for HP-UX.
I have HP rp2470 running HP-UX 10.x
When i run fsck in a root, the output is as below:

#:root> fsck
fsck: /dev/vg00/rlvol1: mounted file system

continue (y/n)? y

Running fsck on mounted filesystems is not recommended. If you do need a full fsck, umount the filesystem first. If it is one of the system required filesystems (such as /var), shutdown the system, boot to single user mode, then run fsck on all the filesystems and then reboot to full multi-user mode.

When running the full fsck, the command to run is "fsck -o full -y /dev/..."

Thanks blowtorch!

I have tried to run fsck -o full and there is a error message like the following:

#:root> fsck -o full /dev/vg00/lvol8
vxfs fsck: file system had I/O error(s) on meta-data.

pass0 - checking structural files
pass1 - checking inode sanity and blocks
vxfs fsck: fsck read failure bno = 1566, off = 0, len = 8192

try including the filesystem type...

/usr/sbin/fsck -F vxfs -o full -y /dev/vg00/lvol8
