Possible installation hang with lvremove

[geofft]

I ran into the lvremove -f /dev/athena/keep_2 from install-debathena.sh hanging on lola-granola. I was attempting to reinstall it after an abortive previous install. We should see if this is reproducible when installing on a machine that has already been partially (or wholly) installed.

Here's the debugging info I got:

   debathena / personal / geofft  17:23  (Geoffrey Thomas)
       .... ... .. why is `lvremove -f /dev/athena/keep_2` hanging in
       sys_semtimedop?
   debathena / personal / geofft  17:24  (Geoffrey Thomas)
       with no other threads?
   debathena / personal / geofft  17:57  (Geoffrey Thomas)
       According to gdb, we're in semop in dm_udev_wait in ?? in
       lv_deactivate in ?? in ?? in lock_vol in lv_remove_single
   debathena / personal / geofft  18:12  (Geoffrey Thomas)
       Also at about the same time I got
       udevd-work[18528]: inotify_add_watch(6, /dev/dm-2, 10) failed: No such
       file or directory
   debathena / personal / geofft  18:12  (Geoffrey Thomas)
       And strace says
       semop(0, {{0, 0, 0}}, 1

If we can't reproduce this and don't see this again, this ticket should be closed.

This was fixed and pushed to production, in that we no longer create that partition and thus don't need to remove it.
