system hangs up after yank two disks during data copying

[lubo1720]

Hi everyone,

I noticed that under some conditions that the illumos will hang up, very
easy to reproduce:
Just create a healthy RAIDz1 pool and copying some data(here I enabled cifs
share),
and then yank two drives.
the system will not respond to any command even you can't login to the
system.

I see someone already fired such a bug, but seems no update:
https://www.illumos.org/issues/1112
Does any one know what happened or is this a ISSUE?
BTW, if there's no data copy, I can use *zpool clear* to recover the pool
and everything looks just fine.

Thanks in advance!

How long did you wait? Default timeouts are 3 minutes before ZFS will declare
the pool as faulted.
