The hardware geometry is 64kx 12, 768k. AFAIK no geometry information has been specified for these device mapper devices (someone else's responsibility). Though I assume dm geometry data is the reason for mkfs.xfs throwing this alert. I don't find anything in /sys/devices/virtual/block/dm-0/ indicating geometry. Any ideas how to verify what's going on here and fix it? Thanks, Stan _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
