One with 6 disks all mirrored for our data and another mirrored pool for the OS. The system has 16GB of RAM. I have a nightly cron script running which takes a snapshot of a particular file system within the storage pool. This has been running for just over a month now without any issues until this weekend. Now we can not access the mentioned file system. If we try to `ls` to it or `cd` into it the shell locks up (not even kill -9 can stop the `ls` processes, etc) and top shows that the process state is `zfs`. This file system is the root of a jail. While the jailed system works fine right now I can not help but feel its time is limited. Any suggestions on how to get this file system functioning normally again? Thanks Jurgen --------------------------> ish http://www.ish.com.au Level 1, 30 Wilson Street Newtown 2042 Australia phone +61 2 9550 5001 fax +61 2 9550 4001
