sunit=value and swidth=value
Used to specify the stripe unit and width for a RAID device or a
stripe volume. value must be specified in 512-byte block units.
If this option is not specified and the filesystem was made on a
stripe volume or the stripe width or unit were specified for the
RAID device at mkfs time, then the mount system call will
restore the value from the superblock. For filesystems that are
made directly on RAID devices, these options can be used to
override the information in the superblock if the underlying
disk layout changes after the filesystem has been created. The
swidth option is required if the sunit option has been speci‐
fied, and must be a multiple of the sunit value.
