Hey, Ranga, Carsten, subscribers.
One option to get this verified is also checking out /proc/mounts. SLES9
has a number of boot scripts that deal with cleaning up "stale" mtab
entries in a slightly erroneous manner, and I have a hunch this might be
one of them.
Yes, cat /proc/mounts shows the mounted lvm.
If there _is_ an entry for /dev/vg0/home in /proc/mounts, you can simply
add it to /etc/mtab using "mount -f /dev/vg0/home" to use default
/etc/fstab options for that mount point, or specify any additional mount
options according to your taste and desire. The "-f" mount(8) option
will simply cause "everything to be done except for the actual
system call", as the manpage explains.
Cool. That worked!
I've done several adjustments to the boot scripts with regard to that
(namely, they simply wipe everything in /etc/mtab out, under the false
assumption they're the first ones to ever touch it), and if anyone is
interested, I can post some patches.
In the other case, I shall be writing a lengthy post one of these days,
as time permits, where I'll be explaining bits and pieces about the
specifics one needs to engage in to make SLES9 support a separate /etc
filesystem, which obviously comes handy when you have to deal with
cloned users.
Hope this helped,
Absolutely. Thank you very much. I have been losing sleep over the mount
issue so much that
I have scheduled a re-IPL for the linux guest on Sunday.
