I had a strange ZFS problem this morning. The entire system would
hang when mounting the ZFS filesystems. After trial and error I
determined that the problem was with one of the 2500 ZFS filesystems.
When mounting that users' home the system would hang and need to be
rebooted. After I removed the snapshots (9 of them) for that
filesystem everything was fine.
I don't know how to reproduce this and didn't get a crash dump. I
don't remember seeing anything about this before so I wanted to
report it and see if anyone has any ideas.
Hmm, that sounds pretty bizarre, since I don't think that mounting a
filesystem doesn't really interact with snapshots at all.
Unfortunately, I don't think we'll be able to diagnose this without a
crash dump or reproducibility. If it happens again, force a crash dump
while the system is hung and we can take a look at it.
