Rather bizarrely, after that second failure I pulled the disk, cleared the
pool, re-inserted it and forced it online. This time, ZFS resilvered fine with
zero errors:
# zpool status
pool: rc-pool
state: ONLINE
status: The pool is formatted using an older on-disk format. The pool can
Just look at this. I thought all the restarting resilver bugs were fixed, but
it looks like something odd is still happening at the start:
Status immediately after starting resilver:

Ross,
I feel you here, but I don't have much of a solution.
The best I can suggest (and has been my solution) is to take out the
problematic disk, copy it to a fresh disk (preferably using something
like dd_rescue) and then re-install.
It seems the resilvering loop is generally a result
Maybe it's the disks firmware that is bad or maybe they're jumpered
for 1.5Gbps on a 3.0 only bus? Or maybe it's a problem with the disk
cable/bay/enclosure/slot?
It sounds like there is more then ZFS in the mix here. I wonder if the
drive's status keeps flapping online/offline and
No, I don't think I need to take a disk out. It's running ok now, it just
seemed to get a bit confused at the start:
$ zpool status

attempt was made to correct the error.
Gaaah, looks like I spoke too soon:
$ zpool status
pool: rc-pool
state: DEGRADED
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are unaffected.
action: Determine if the device needs to be replaced, and clear
Ross,
The disks do have problems - that's why I'm resilvering.
I've seen zero read, write or checksum errors and had it loop. Now I
do have a number of read errors on some of the disks, but I think
resilvering is missing the point if it can't deal with corrupt data or
disks with a small
