growpart disk partition
rewrite partition table so that partition takes up all the space it can
options:
-h | --help print Usage and exit
--fudge F if part could be resized, but change would be
less than 'F' bytes, do not resize (default: 1048576)
-N | --dry-run only report what would be done, show new 'sfdisk -d'
-v | --verbose increase verbosity / debug
-u | --update R update the the kernel partition table info after growing
this requires kernel support and 'partx --update'
R is one of:
- 'auto' : [default] update partition if possible
- 'force' : try despite sanity checks (fail on failure)
- 'off' : do not attempt
- 'on' : fail if sanity checks indicate no support
Example:
- growpart /dev/sda 1
Resize partition 1 on /dev/sda
must supply disk and partition-number
