Chris,
We are using XFS, the spare and parity drives are kept in a seperate
jbod case w/ seperate controller, so it would seem we are indeed
striping across controllers (we've had one drive fail so we are using a
spare in that seperate case now). We are using two luns and mount them
seperately as we had some problems with XFS and LVM recognizing volumes
greater than 2Tb. Again I didn't set the SAN up .. I'm going to do more
research in this direction though.
Cheers
Todd
