     zpool-offline — take physical devices offline in ZFS storage pool

SYNOPSIS

     zpool offline [--power|[-ft]] pool device…
     zpool online [--power] [-e] pool device…

DESCRIPTION

     zpool offline [--power|[-ft]] pool device…
             Takes the specified physical device offline.  While the device is offline, no
             attempt is made to read or write to the device.  This command is not applicable to
             spares.

             --power
                     Power off the device's slot in the storage enclosure.  This flag currently
                     works on Linux only

             -f      Force fault.  Instead of offlining the disk, put it into a faulted state.
                     The fault will persist across imports unless the -t flag was specified.

             -t      Temporary.  Upon reboot, the specified physical device reverts to its
                     previous state.

     zpool online [--power] [-e] pool device…
             Brings the specified physical device online.  This command is not applicable to
             spares.

             --power
                     Power on the device's slot in the storage enclosure and wait for the device
                     to show up before attempting to online it.  Alternatively, you can set the
                     ZPOOL_AUTO_POWER_ON_SLOT environment variable to always enable this
                     behavior.  This flag currently works on Linux only

             -e      Expand the device to use all available space.  If the device is part of a
                     mirror or raidz then all devices must be expanded before the new space will
                     become available to the pool.
