To repair a file system in HPUX

# fsck -F vxfs -y -o full /dev/vg##/lvol#
-or-
# fsck -F vxfs -o full -y /mount_pt

Note: The HFS file system has been obsoleted in HP-UX since version 10, except for the /stand file system which contains the kernel, and you’re not going to unmount the kernel and run a file system check. Instead, get to single user. Here is one way:

# reboot
# interact with IPL . yes
ISL>hpux -is

And as the kernel is loaded vg00 will be enabled and automatically checked for corruption.

# init 2, same thing, automatically check run level 2
# init 3, same thing, automatically check run level 3, multiprocessor mode. The system is up.

NEVER! fsck /stand – The only hfs file system for over a decade is /stand, and you never fsck /stand!

Don’t try that on Ubuntu 10.04.
It will just shut down the system.

Excellent article!!
Is there a way to do this via SSH?
What methods do you recommend for listing the mounted file systems?
Thanks!

This post is over two years old but still relevant today.

I just used most of the steps described here to repair an ext3 partition on my Ubuntu desktop system. Only difference being I did not do “init 1″. I logged out to the gdm screen then did Ctl-Alt-F2 to get to a virtual console. I logged into the system and ran the commands with the exception of “init 1″.

Thanks for a very helpful and concise article.

How do you find out what the actual device name is?

@Jack, I think that’s when you need to use a rescue disk. Most of the distros have this on their installation media.

How do you check the / partition – which cannot be unmounted since it still shows as “in use” after going to run level 1? Is there a way without rebooting?

Thankyou – this page saved my life! (well, not literally). After checking loads of links that just told me what it said in the man page, here was a quick, easy and practical way to use the command.

thanks for HP/UX JFS repair commands :)

Commands are same but syntax changes.

To repair HFS file system (/home)

umount /home
fsck –F hfs /dev/vg00/lvo1
mount /home

To repair JFS file system (/home)
umount /home
fsck –F vxfs /dev/vg00/lvo14
mount /home

Replace /dev/XXX/YYY with actual device file.
