I just did a zpool replace on a new drive, and now it's resilvering.
Only, when it gets about 20mb resilvered it restarts. I can see all the
drive activity simply halting for a period then resuming in gstat. I see
some bugs in the opensolaris tracker about this, but no resolutions. It
doesn't seem to be related to calling "zpool status" because I can watch
gstat and see it restarting... Anyone seen this before, and hopefully have
a workaround...?
The pool lost a drive on Wednesday and was running with a device missing,
however due to the device numbering changing on the scsi bus, I had to
export/import the pool to get it to come up, the same for after replacing
it.
