/usr can't mount

[Krish Rajan]

In Single user mode /usr unable to mount even after issuing mount -a
option. This system has been configured using LVM and the filesystem
type we are using is VXFS on HPUX 10.20 , model of the server is D270. I also did fsck -o full but with no luck to mount.

What error message do you get? What does fsck report? What kind of filesystem is this: HFS or JFS?

Hi,
What is the result of :

#mount /dev/vg00/lvol7 /usr
?

mount -a will mounts all file systems in your /etc/fstab, so check this file first, another point I though of is the error message, any message, which you can find some hints?

[Krish Rajan]

After I did fsck, the filesystem has no errors.
Then When I try to mount, I get unknown filesystem type vxfs.

Hi:

Try:

# mount -F vxfs /dev/dsk/cXdYtZ /usr

...JRF...

[Carsten Krege]

"fsck -o full" succeeds, but mount does not?? I would try to mount it read-only first and if this succeeds, reboot.

# mount -F vxfs -r /usr

You can also try this one:

# /sbin/fs/vxfs/mount -r /usr

I tried this command and Got Success. Thanks every body.

You might also want to check whether you have the vxbase driver in the kernel:

# cd /tmp
# /usr/lbin/sysadm/system_prep -s system
# grep vxbase system
