ZPOOL-CLEAR(8)          FreeBSD System Manager's Manual         ZPOOL-CLEAR(8)

NAME

     zpool-clear - clear device errors in ZFS storage pool

SYNOPSIS

     zpool clear [--power] pool [device]<?>

DESCRIPTION

     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.

     If the pool was suspended it will be brought back online provided the
     devices can be accessed.  Pools with multihost enabled which have been
     suspended cannot be resumed when there is evidence that the pool was
     imported by another host.  The same checks performed during an import
     will be applied before the clear proceeds.

     --power
             Power on the devices's slot in the storage enclosure and wait for
             the device to show up before attempting to clear errors.  This is
             done on all the devices specified.  Alternatively, you can set
             the ZPOOL_AUTO_POWER_ON_SLOT environment variable to always
             enable this behavior.  Note: This flag currently works on Linux
             only.
