Your server has a ZFS storage pool that is configured as follows:
The server has two spate 140-GB disk drives: c3t5d0 c3t6d0
Which command would add redundancy to the pool1 storage pool?
A.
zpool attach pool1 c3t5d0 c3t6d0
B.
zpool attach pool1 c3t3d0 c3c5d0; zpoo1 attach pool1 c3t4d0 c3t6d0
C.
zpool mirror pool1 c3t5d0 c3t6d0
D.
zpool add pool1 mirror c3t5d0 c3t6d0
E.
zpool add raidz pool1 c3t5d0 c3t6d0
Explanation:
You can convert a non-redundant storage pool into a redundant storage pool by using the zpool attach
command.
Note: zpool attach [-f] pool device new_device
Attaches new_device to an existing zpool device. The existing device cannot be part of a raidz configuration. If
device is not currently part of a mirrored configuration, device automatically
transforms into a two-way mirror of device and new_device. If device is part of a two-way mirror, attaching
new_device creates a three-way mirror, and so on. In either case, new_device begins to resilver immediately.
