Lance:
am I correct in saying that the mount point for the /dev/opt/opt (lvm) file
system is /opt?
The approach I follow when creating something like an /opt is to create an
/opt-bkup before proceeding (ie. copy recursive opt to opt-bkup).
Then I create the vgopt and lvopt (lvm) so I don't have to be checking my
glasses by seein double images: opt opt.
Then, I manually go through the process (i.e. no yast) and go as far as the
step when I am supposed to mount the /opt for the LVM (vgopt and lvopt).
Instead of mounting on /opt, I munt on /mnt/copy so I can populate my new
LVM with data from my /opt-bkup.
Then, I just go to my /etc/fstab, point my LVM to /opt and I reboot.
What you may want to do is remove the LVM info pointing in /etc/fstab point
your /opt to /dev/opt/opt. If your original /opt has not been corrupted,
you should be OK. If you did it through yast and yast tried to delete /opt
before creating it, your data might be gone and your backup will become
your best friend.
Hope this help and thank you for reminding us all about doing our backups.

Need some guidance here
We issued the shutdown command for a Linux test image and after it
went down we IPL'ed the LPAR. In the boot process coming up we are
receiving a the message that /dev/opt/opt a LVM reiserfs file system
has problems. I can see from the log that FSCK has tried to fix the
problem, but is unable to. It then issues the message to run it
manually.
I have attempted to run it manually issuing the command FSCK.REISERFS
--rebuild-sb /dev/opt/opt. When I issues this command it tells me it
cannot find the device? Anyone have thoughts as to how I could recover
this?
We were lacks and had not yet made backups of this LVM file system ,
so I can not restore it from a back-up. I do have a TAR file back-up of
the complete system that resides on another LVM file system. This could
be used to rebuild the systems, if I could get the system up. But can
not access this because the system does not boot up high enough to get
to these files. Is their a way to bypass what's on /opt and get the
system up? I could then make a new /opt filesystems if I could just get
the system up.
Another thought I had was to modify the /etc/fstab file and take the
entry for /dev/opt/opt out of it. But, we are unable to connect to the
partition via ssh. I am communicating with the system via the HMC
reading the message console for the LPAR? Using this method the screen
are not friendly and trying to use VI is impossible, as I can't read the
screen when in VI from the message console.
Thanks for your comments and advice ,
