What command > prints this message? It comes from a regularly scheduled health check script whose relevant portion is: condition=$(/sbin/zpool status | egrep -i '(DEGRADED|FAULTED|OFFLINE|UNAVAIL|REMOVED|FAIL|DESTROYED|corrupt|cannot|unrecover)') if [ "${condition}" ]; then emailSubject="`hostname` - ZFS pool - HEALTH fault" problems=1 fi Given that the status is none of the above I infer that one or more of the words |corrupt|cannot|unrecover| appeared in whatever message zpool status emitted. However, running this command from the command line produces nothing containing any of the trigger words. > > Because the pool is perfectly healthy.
