Fsadm utility to resize or check filesystem on a device
fsadm [options] check device
fsadm [options] resize device [new_size[BKMGTEP]]
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.
Unmount ext2/ext3/ext4 filesystem before doing resize.
Bypass some sanity checks.
Display the help text.
Print commands without running them.
Be more verbose.
Answer "yes" at any prompts.
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
The temporary directory name for mount points. Defaults to "/tmp".
The device directory name. Defaults to "/dev" and must be an absolute path.
