yep - the policy gets set on the controller for everything served by it .. you could put the ZIL LUN on one controller and change the other controller from write back to write through, but then you essentially waste a controller just for the log device and controller failover would be a mess .. we might as well just redo the fcode for these arrays to be a minimized optimized zfs build, but then again - i don't know what does to our OEM relationships for the controllers or if it's even worth it in the long run .. seems like it might be easier to just roll our own or release a spec for the hardware vendors to implement. --- .je _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
