Hi all,
I have a interesting one. I have a disk wedged in a zpool.
It can be seen from format and a analyze works fine, but from zfs the
system has it marked as unavailable. (Yes the disk is probably flaky...
I don't get my hands on the good disks)
The system is 5.11 snv_55 sun4u sparc SUNW,Sun-Blade-100 and the
storage is a D1000.
rebooting makes no difference to the state.
The recommendations from "zpool status" was to either "zpool online" the
device or to "zpool replace" the device. Neither worked.
I also tried physically unplugging the disk and reconfiguring the device
tree.. No difference.
To get it back I had to export and import the pool.
Of course the disk had a lot of checksum errors (ass you would expect),
but a scrub fixed them all up. You got to love ZFS :-)
See the output from the z commands below.
_
_Any Idea's on what was the correct way to revive the disk. If it
happens again I will force a dump.
Regards
Rodney Lindner.
