This works, pool turns int SUSPENDED mode, BUT after that there is nothing I can do with it, I cant export/re-import this disk or destroy pool0 without system reboot. rmmod zfs no help too.
So how you guys test ZFS without reboot?
If reboot is obligatory (this sucks) .. what tools do you use to test it, do you have some kind of manually setup linux images for that ?

How to properly test fault tolerance of ZFS and what utilities do you use for this? I want to test disk-failure / power failure tolerance of ZFS.
I tried standard "faulty" tool to emulate disk IO failures:
mdadm -B /dev/md666 -l faulty -n1 /dev/sda_ zpool create pool0 /dev/md666
zfs create test pool0 mdadm -G /dev/md0 --layout=wp10000 dd if=/dev/random of=/pool/test/trash bs=1M count=10 sync
This works, pool turns int SUSPENDED mode, BUT after that there is nothing I can do with it, I cant export/re-import this disk or destroy pool0 without system reboot. rmmod zfs no help too.
