NAME

fsadm --- utility to resize or check filesystem on a device

SYNOPSIS

fsadm [options] check device

fsadm [options] resize device [new_size[BKMGTEP]]

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.:
-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
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.:
