Hello.
I apologize for the mistakes and omissions in my original posting. I've
included additional information in this message.
I'm running Vinum on a Free BSD 4.9 system with 3 hard drives. It's =
been
operational for about 5 years. The first drive is a small one and I =
boot from
it. The second and third drive are mirrored, using Vinum, and contain =
most of
the system's data (1 volume, 1 plex per drive, 1 subdisk per plex). The
operating system and Vinum are stock, no modifications. The Vinum =
config has
not been modified in years.
The system locked up on me this morning. When I rebooted there was a =
problem
with the Vinum mirrored drives. When I did a "list" from Vinum both =
subdisks
were "stale" and both plexes were "faulty".
After playing around a while, I didn't know what to do, so I stupidly =
tried
something which probably made things worse. I did a "start" on one of =
the
plexes. It took a few minutes and then came up along with the subdisk =
on it.
But I'm afraid that it seems to be empty.
When I boot now I get a "bad super block: magic number wrong" error, =
along
with "unexpected soft update inconsistency", "/dev/vinum/mirror: cannot =
figure
out file system partition".
Vinum now lists the drives as "up", the volume as "up", the plexes as =
"up" and
"faulty", the subdisks as "up" and "stale". I would love to post a copy =
of
the Vinum "list" but I don't know of any way to copy it from the console =
to
here.
Unfortunately, the /var/log directory is on the Vinum drive. So I am =
unable
to access it.
Bottom line: I'm guessing that I blew away the first plex. Is there a =
way to
tell? Is there any way to get the second plex up and running, and to =
restore
the first plex from it?
Thanks,
John

I can't guess what you did.

Maybe.
Please read http://www.vinumvm.org/vinum/how-to-debug.html, retrace
your steps and see if you can work out what you did wrong. If not,
please supply the information asked for there, and maybe somebody will
be able to help you.
