I also have an entry in my fstab

Code:
root@orca:~# cat /etc/fstab
proc            /proc           proc    nodev,noexec,nosuid 0       0
# / was on /dev/sda5 during installation
UUID=b57eae64-f270-4825-9ff0-040264fb33ac /               ext3    errors=remount-ro 0       0
# /home was on /dev/sdb1 during installation
UUID=c2d5decb-0615-48bd-9f8f-40eba852329e /home           ext3    defaults        0       0
# swap was on /dev/sda1 during installation
UUID=54582723-d970-46f4-a24d-9c6d25ca16c6 none            swap    sw              0       0
/dev/orcafiler1/orcavolume       /data    ext3  defaults 0 0
However when I run "mount -a", I get this error

Code:
root@orca:~# mount -a
mount: special device /dev/orcafiler1/orcavolume does not exist
Also /data is now empty! How can I fix that?

Thanks. After running that command, it said the volume is now active!
I wonder why the volume went inactive?!!

Probably because you were editing/creating it. It can't be active during those procedures

Now it is permanently active or not? I mean should I run that command after every boot?
Since it is a sever and users use that, it is not possible to test that at the moment.

Try a reboot and see.
When I setup slackware on LVM I don't have to do it twice, only after I've created the layout. But try a reboot and see
