NAME

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 or force-fault it. While the device is offline or force-faulted, no attempt is made to read or write to the device. dRAID spares can not be offlined or force faulted. Traditional spares can only be offlined or force-faulted when they are active.
- --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.
