I recently added a Crucial 64GB SSD drive that I had lying around to my zfs
pool. unfortunately, it keeps dropping off and I'm not sure why. The drive
wasn't failed when I removed it from an old laptop. It has happened twice
and only system restart brings it back. Here are the log messages, they
repeat but here is the base mess:
zpool status
pool: zrewt
state: ONLINE
status: One or more devices has been removed by the administrator.
Sufficient replicas exist for the pool to continue functioning in a
degraded state.
action: Online the device using 'zpool online' or replace the device with
'zpool replace'.
scan: none requested
config:
