And I created the > partitions starting sector 512, so that should be good also. -b size=4096 is the default anyway, for 4k sector drivers you also want -s size=4096, which you do not want for 512 byte sector disks. What values do the files /sys/block/<device>/queue/logical_block_size /sys/block/<device>/queue/physical_block_size /sys/block/<device>/alignment_offset say about your disk? _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
