I haven't test all mkfs.* but... mkfs.xfs just works with 1M physical_block_size. mkfs.ext4 won't by default but -F "fixes" that: # mkfs.ext4 -b 4096 -F /dev/mapper/20017380023360006 mke2fs 1.41.12 (17-May-2010) Warning: specified blocksize 4096 is less than device physical sectorsize 1048576, forced to continue ... I'll check fdisk and parted tomorrow (I know lvm2 doesn't look at physical_block_size). -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
