--------------------+------------------------------------------------------- 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.
