Hi,
   I have a simple question:
    Can software raid survive one disk hot unplug when the raid is under
heavy load?

    During my test (3ware 7500-8 jbod mode, software raid 5), I ran bonnie++
on the
top of md and then unplugged one disk. I saw a lot of scsi disk errors from
dmesg, and then
scsi layer marked this disk offline. Finnally md detected disk failure and
mark this disk
as faulty. But bonnie++ still hangs there with state 'D' which could not be
killed by -9.

Thanks!
