Can I set innodb O_DIRECT for ZFS file system ? (no replies)

I'm using the mysql 5.5.30 innodb engine , the data are saved in a RAID5 storage array , the partition of storage is configured as ZFS file system, Solaris 10 OS.

Can I set innodb_flush_method parameter to O_DIRECT ? From some article , the ZFS doesn't support O_DIRECT , is it correct ?

please advise , thanks.
