NAME

vdoformat - format a VDO device

SYNOPSIS

vdoformat [options...] filename

DESCRIPTION

vdoformat formats the file named by filename as a VDO device. This is analogous to low-level device formatting. The device will not be formatted if it already contains a VDO, unless the --force flag is used.

vdoformat can also modify some of the formatting parameters.

OPTIONS

Format the block device, even if there is already a VDO formatted thereupon.
Print this help message and exit.
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.
Specify the slab size in bits. The maximum size is 23, and the default is 19.
Specify the frequency of checkpoints. The default is never.
Specify the amount of memory, in gigabytes, to devote to the index. Accepted options are .25, .5, .75, and all positive integers.
Specify whether or not to use a sparse index.
