fsadm

utility to resize or check filesystem on a device

SYNOPSIS

0 5 fsadm [options] check device fsadm [options] resize device [new_size]

DESCRIPTION

fsadm utility checks or resizes the filesystem on a device. It tries to use the same API for ext2, ext3, ext4, ReiserFS and XFS filesystem.

OPTIONS

-e|--ext-offline
Unmount ext2/ext3/ext4 filesystem before doing resize. -l|--lvresize
Resize given device if it is LVM device. -f|--force
Bypass some sanity checks. -h|--help
Display the help text. -n|--dry-run
Print commands without running them. -v|--verbose
Be more verbose. -y|--yes
Answer "yes" at any prompts. -c|--cryptresize
Resize dm-crypt mapping together with filesystem detected on the device. The dm-crypt device must be recognizable by cryptsetup(8). new_size[B|K|M|G|T|P|E]
Absolute number of filesystem blocks to be in the filesystem, or an absolute size using a suffix (in powers of 1024). If new_size is not supplied, the whole device is used.

DIAGNOSTICS

On successful completion, the status code is 0. A status code of 2 indicates the operation was interrupted by the user. A status code of 3 indicates the requested check operation could not be performed because the filesystem is mounted and does not support an online fsck(8). A status code of 1 is used for other failures.

EXAMPLES

Resize the filesystem on logical volume /dev/vg/test to 1000 megabytes. If /dev/vg/test contains ext2/ext3/ext4 filesystem it will be unmounted prior the resize. All [y/n] questions will be answered 'y'.


fsadm -e -y resize /dev/vg/test 1000M

ENVIRONMENT VARIABLES

TMPDIR The temporary directory name for mount points. Defaults to " /tmp ".

DM_DEV_DIR The device directory name. Defaults to " /dev "and must be an absolute path.
