Hi,
I''m new in this mail list and my english is very bad.
I installed opensolario 0811, and I created a pool_nas raidz1 with 3 discs:
zpool create -f pool_nas raidz1 c3d0 c3d1 c4d0
zpool status pool_nas
pool: pool_nas
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
pool_nas ONLINE 0 0 0
raidz1 ONLINE 0 0 0
c3d0 ONLINE 0 0 0
c3d1 ONLINE 0 0 0
c4d0 ONLINE 0 0 0
errors: No known data errors
My question is that is possible add a new disc c4d1 to the exist raidz1
pool, not at the pool only with no lose data.
I think its not possible but i don''t find any documentation about it.
Thanks a lot.

If you haven''t filled the pool more than 1 disk worth, you can juggle the data around.. * Create a new pool with just one disk, copy everything over (either via zfs send+recv or just plain copy). * Create a 4 disk raidz1 with one disk missing: * mkfile -n 250g /tmp/blah (if the disks are 250g) * zpool create pool_nas raidz1 c3d0 c3d1 c4d0 /tmp/blah * fail the /tmp/blah device * copy everything back * destroy temporary 1-disk pool * replace /tmp/blah with the single disk in the new pool /Tomas -- Tomas ?gren, stric at acc.umu.se, http://www.acc.umu.se/~stric/ |- Student at Computing Science, University of Ume? `- Sysadmin at {cs,acc}.umu.se
