Hi TianHong,
I have seen similar apparent hangs, all related to destroying large snapshots,
file systems
or deleting large files ( with dedup enabled. by large I mean in the terabyte
range)
In the cases I have
Just detach the faulty disk, then the spare will become the normal
disk once it's finished resilvering.
#zfs detach pool fault_device_name
Then you need to the new spare :
#zfs add pool new_spare_device
There seems to be a new feature in illumos project to support a zpool
property like spare
and get threadlist.
8. Eventually, I have to power cycle the box.

You are most welcome.

Thanks for the reply.
This sounds a serious issue if we have to reboot a machine in such case, I am
wondering if anybody is working on this.
BTW, the zpool failmode is set to continue, in my test case.
