I did some tests with that array, as I did with an Infortrend OXYGENRAID device and an old LSI FC array.

Solaris 10: New ZFS version -> gzip compression

| | TrackBacks (0)
With patch 137137-09 (SPARC) and 137138-09 (x86), Solaris 10 can handle zfs pools with version 10. You will have to upgrade your zpools; "zpool status" will result in this warning:

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.


To upgrade, use the command

# zpool upgrade yourpoolname

The GZIP compression known by OpenSolaris and Solaris Express is now in the Solaris 10 code base starting from (kernel) patch 137137-09/137138-09.

You may set:

# set compression=gzip mypool/test

and - to set a gzip compression level:

# set compression=gzip-9 mypool/test
