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.
