Sorry I can't comment on MPxIO, except that I thought zfs could by itself discern two paths to the same drive, if only to protect against double-importing the disk into pool.

I am not sure it is a good idea to use such low protection (raidz1) with large drives. At least, I was led to believe that after 2Tb in size raidz2 is preferable, and raidz3 is optimal due to long scrub/resilver times leading to large timeframes that a pool with an error is exposed to possible fatal errors (due to double-failures with single-protection). //Jim _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
