Cannot unmount a filesystem

hp_user_1 — Wed, 07 Sep 2005 08:51:30 GMT

Hi,

I am using VCS on hpux 11i. I tried to bring up a servicegroup through VCS on one of the nodes in the cluster. All but one filesystems were mounted successfully. For the one the mount point was missing. I created the mount point on the fly and then VCS mounted that filesystem on it successfully. Then I brought down the servicegroup on the node. All but that particular filesystem were unmounted. I am trying to umount the filesystem as follows:

# umount /opt/oracle/data1

but it says:

Block device required.

I tried with the block device but no luck.

Can anyone help.

Points will be awarded.
Thanks

Is there an entry for that path in /etc/fstab? Maybe there is an inconsistency there?

When you run the command:

umount /opt/oracle/data1

the filesystem code looks in /etc/fstab to translate the mountpoint into a device file such as /dev/vg04/lvol22. Check /etc/fstab to see that the source for the data1 mountpoint is correctly spelled.

Hy,
try with the lvol:

umount /dev/vgXX/lvolXX

related at the /opt/oracle/data1 file system

There is no entry in /etc/fstab file. The mount point is defined in VCS main.cf file.

Umount requires special file as argument,
try
bdf /opt/oracle/data1
check the lvol related and then
umount /dev/vgXXX/

I tried with lvol also but same error message.

Asghar,

Can you send us the main.cf
Perhaps there is an error in this file

Please check /etc/fstab and manaly mount/ umount the filesystem , after a reboot may help.

You can check the filesystem details , with
#fstyp -v /dev/vg00/lvolx

Cheers,
Raj.

I don't see the mountpoint that you're talking about in the main.cf file that you'ave pasted here. Also the block device file in your particular case would be of the form..."/dev/vx/dsk/XXXX" NOT /dev/vgXX/lvolXX

I rebooted the box and the problem resolved. I did the same thing again to recheck and everything went smooth.
Thanks for your help.
