FreeBSD ZFS raidz1 Started a (da59) drive replacement. During resilver, second drive (da60) failed

Our system started slowing down... Found a couple of drives in the same raid that looked scary.Replaced the drive that S.M.A.R.T. marked as failure eminent. (da59)

Then da60 started to error.Finally the system marked it "removed".

da59 was working before the replacement

Is there a way to start over? Stop or offline the replacement process,force the original da59 back online, then replace drive (da60) that must have beenworse off then da59?

Code:

      raidz1-7                 DEGRADED 14.2K     0 12.2K        da56                   ONLINE       0     0     0        da57                   ONLINE       0     0     0        da58                   ONLINE       0     0     0        replacing-3            DEGRADED 14.2K     0     0          1386012792062170018  OFFLINE      0     0     0  was /dev/da59/old          da59                 ONLINE       0     0     0  (resilvering)        13092123056171323448   REMOVED      0     0     0  was /dev/da60        da61                   ONLINE       0     0     0        da62                   ONLINE       0     0     0        da63                   ONLINE       0     0     0

The zpool's name is tank

Here's my command plan,

zpool online tank 13092123056171323448 da60

zpool clear tank da60

watch status to see da60 online

then:zpool offline tank replacing-3

once offline, pull "new" da59 and insert "old" da59wait to see if the system recognizes "old" da59

then:zpool online tank 1386012792062170018 da59

once da59 is online, if replacing-3 is still present

then:zpool detach replacing-3

assuming the system is feeling better

then:zpool offline tank da60

pull "old" da60 drive and insert "new" da60wait for it to be recognized

then:zpool replace tank 13092123056171323448 da60

Hopefully there is enough life in "old" da59 to allow fornew da60 to resilver....

Is there merit in my idea?Thanks, - Jon
