Is there a way to convert a 2 disk raid-z file system to a mirror without
backing up the data and restoring?
We have this:
bash-3.00# zpool status
pool: archives
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
archives ONLINE 0 0 0
raidz1 ONLINE 0 0 0
c1t2d0 ONLINE 0 0 0
c1t3d0 ONLINE 0 0 0
... and what I would like to be able to do is to:
- remove c1t3d0 from the raidz, leaving it in degraded mode momentarily.
- Create a new pool with the single disk c1t3d0
- copy the data from the current pool to the new pool
- destroy the current pool
- attach c1t2d0 to the new pool, creating a mirror
I can't seem to find any way to remove c1t3d0 from the raidz pool. The best I
can do is "offline" it, which proves the pool can still run without the disk,
but I can't seem to free the disk.
Any ideas?
Brian
