RAID 1 has no "layout" (for RAID, that usually refers to striping in RAID levels 0/5/6), so there's nothing for a filesystem to detect or optimize for. The chunk size above is for the md-RAID write-intent bitmap; that's not exposed information (for any RAID system that I'm aware of, software or hardware) or something that filesystems can optimize for. -- Chris Adams <[email protected]> _______________________________________________ CentOS mailing list [email protected] https://lists.centos.org/mailman/listinfo/centos
