Clears device errors in a pool.
If no arguments are specified, all device errors within the pool are cleared.
If one or more devices is specified, only those errors associated with the
specified device or devices are cleared.
.Pp
If the pool was suspended it will be brought back online provided the
devices can be accessed.
Pools with
.Sy multihost
enabled which have been suspended cannot be resumed.
While the pool was suspended, it may have been imported on
another host, and resuming I/O could result in pool damage.

This is done on all the devices specified.
Alternatively, you can set the
