[OpenIndiana-discuss] Hanging zfs commands

[Hans Joergensen]

Hey,

Somehow I've hit somekind of lock on one of my NAS-boxes....

Output from ps;

Any chance I can get around this without rebooting the machine? it's
a production system with lots of VM's on it.. So that would be very
annoying..

I've tried solving the problem by killing the processes that spawned
the zfs list and destoy commands, thats why they have 1 as parant
process...

Could the lock have happened because of PID 26707 and 26705 running
at the same time?
