Hello experts,
I have a solaris 10 (SunOS 5.10 Generic_148888-05 sun4u sparc SUNW,SPARC-Enterprise) that by mistake I added a second san space of 700g to the pool. the whole pool is now 1.2T and, I need to take the space away from the pool and, make the pool 700g total. this is live oracle filesystem. I have not done any zfs shrinking of sort (I know you can not do this). Here is my zpool status
# zpool status DLMS01Cpool
pool: DLMS01Cpool
state: ONLINE
status: The pool is formatted using an older on-disk format. The pool can
still be used, but some features are unavailable.
action: Upgrade the pool using 'zpool upgrade'. Once this is done, the
pool will no longer be accessible on older software versions.
scan: resilvered 392G in 2h36m with 0 errors on Thu Apr 19 20:08:46 2012
config:
NAME STATE READ WRITE CKSUM

c3t50002AC21226072Bd0 ONLINE 0 0 0
errors: No known data errors
what are my best options? Can you give me the commands please?
