RE: [dm-devel] FS directly on top of dm devices?

["Romanowski, John (OFT)" <John Romanowski oft state ny us>]

Partitioning and LVM is optional, depends upon what you want to accomplish.
Sometimes I make the file system directly on the multipathed device, as in
mkfs /dev/mapper/mpatha

Other than having more paths to the LUN it's no different then making a file system on an unpartitioned scsi device as in
mkfs /dev/sda
