You can add disks to to a RAID-Z configuration. The following shows how
to convert a storage pool with one RAID–Z device to storage pool with
two RAID-Z devices with 3 disks.
# *zpool status*
pool: rpool
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
raidz1 ONLINE 0 0 0
c1t2d0 ONLINE 0 0 0
c1t3d0 ONLINE 0 0 0
c1t4d0 ONLINE 0 0 0
errors: No known data errors
# *zpool add rpool raidz c2t2d0 c2t3d0 c2t4d0*
# *zpool status*

Hi,
okay sorry. I want to migrate from non raid single disks to zfs raidz - at the
moment i have 1 empty disk and 4 with data.
Its possible to create a pool at the beginning with one disk and add later disk
2,3,4,5 and can the pool be a raidz then with single parity?
So ists possible for me to transfer the data.
kind regards
Hi robert.hoppe,
could you be more specific about your situation please ?
U wrote ntfs, but where is the problem with zfs ?
I you create a pool, you can add disks later # |zpool add xpool c1t0d0
kind regards,

Hi there,
i'm building a small NAS with 5x1TB Disks. The disks contains at the moment
some data, ntfs as the fs and aren't a raid.
Now my im wondering if its possible to add the parity later. So that i add
step by step one disk to the pool. And when i add the last disk, i enable the
parity.
(i have only one another 1 tb disk to backup the files)
Thank you for you replies and sorry for my bad english.
Robert Hoppe
