Since I got my zfs pool working under solaris (I talked on this list
last week about moving it from linux & bsd to solaris, and the pain that
was), I'm seeing very good reads, but nada for writes.
Reads:
r...@shebop:/data/dvds# rsync -aP young_frankenstein.iso /tmp
sending incremental file list
young_frankenstein.iso
^C1032421376 20% 86.23MB/s 0:00:44
Writes:
r...@shebop:/data/dvds# rsync -aP /tmp/young_frankenstein.iso yf.iso
sending incremental file list
young_frankenstein.iso
^C 68976640 6% 2.50MB/s 0:06:42
This is pretty typical of what I'm seeing.
r...@shebop:/data/dvds# zpool status -v
pool: datapool
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.
scrub: none requested
config:

(This is while running an rsync from a remote machine to a ZFS filesystem)
