VDOFORMAT(8)

NAME
vdoformat - format a VDO device

SYNOPSIS
vdoformat [options...] filename

DESCRIPTION

vdoformat can also modify some of the formatting parameters.

--logical-size=size
    Set the logical (provisioned) size of the VDO device to size. A size suffix of K for kilobytes, M for megabytes, G for gigabytes, T for terabytes, or P for petabytes is optional. The default unit is megabytes.

--slab-bits=bits
    Specify the slab size in bits. The maximum size is 23, and the default is 19.
