mbralign - Align MBR partition table based vmdk files to NetApp storage systems

Usage: mbralign [OPTION]... SOURCE
or: mbralign [OPTION]... SOURCE DEST
or: mbralign [OPTION]... SOURCE DIRECTORY
Options:
--sparse The resulting file will be sparse. This option is
designed for NetApp NFS based datastores.
--force The default behavior is to skip properly aligned disks.
The --force option can be used to
override this. (Useful for migrating and making sparse).
--bs=n Use n as the block size (specified in kB). n must be one
of (8, 16, 32, 64, 128, 1024). The default is 8.
--preview Show what would be done, then exit. No changes are made
to the file.
--quiet Only print warnings and errors (no other status isi
printed to screen).
--debug Print debug comments.
--help Print usage.
--thereAreNoVmSnapshots Suppress the warning message about snapshots and
answer YES to the question of whether to continue.
