fsadm --- utility to resize or check filesystem on a device
fsadm [options] check device fsadm [options] resize device [new_size]
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.
-e|--ext-offline Unmount ext2/ext3/ext4 filesystem before doing resize. -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. 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.
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.
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
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.
