ZFS raidz

[Baho Utot]

I have created a ZFS raidz file system.

Created like this:

The partitions are all the same and the drives are three identical drives.

# zpool create storage raidz /dev/ada1p1 /dev/ada2p1 /dev/ada3p1
# zpool status
pool: storage
state: ONLINE
scan: none requested
config:

NAME STATE READ WRITE CKSUM
storage ONLINE 0 0 0
raidz1-0 ONLINE 0 0 0
ada1p1 ONLINE 0 0 0
ada2p1 ONLINE 0 0 0
ada3p1 ONLINE 0 0 0
The filesystems created

|# zfs create storage/home|
|||# zfs create storage/ports|
||
|||# zfs set compression=gzip storage/home|
|||# zfs set compression=gzip storage/ports|
||
|||# zfs set mountpoint=/usr/home storage/home|
|||# zfs set mountpoint=/usr/ports storage/ports|


Can addtional drive(s) be added to it?

What are the downfalls if I add drives?
