Package: lvm2
Version: 2.02.88-2
Severity: normal
Tried and failed to remove an LVM snapshot:
root@cel:~
# lvremove vg_cel/backups-20110930
Do you really want to remove active logical volume backups-20110930? [y/n]: ^C
Logical volume backups-20110930 not removed
root@cel:~
# lvchange -an vg_cel/backups-20110930
Can't change snapshot logical volume "backups-20110930"
root@cel:~
# lvremove vg_cel/backups-20110930
Do you really want to remove active logical volume backups-20110930? [y/n]: y
Unable to deactivate open vg_cel-backups--20110930-cow (254:35)
Failed to resume backups-20110930.
libdevmapper exiting with 7 device(s) still suspended.
At this point now the entire LVM subsystem is totally frozen. No commands
ever complete. Any LVM-related command hangs and is not SIGKILLable.

# ps -ef | grep lvs

I tried to strace it to see what it was blocked on. Even strace now hangs:
root@cel:~
# strace -p 31791
Process 31791 attached - interrupt to quit
^C
^C
strace is at least killable though:
^Z
[1]+ Stopped strace -p 31791
root@cel:~
# kill %1
[1]+ Stopped strace -p 31791
root@cel:~
# kill -9 %1
[1]+ Stopped strace -p 31791
root@cel:~
#
[1]+ Killed strace -p 31791
In this state the only remedy I have found is a complete reboot of the system.
Other existing LVs do appear to be functioning normally, however, and the
machine generally works fine.
