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.
|Unmount ext2/ext3/ext4 filesystem before doing resize.
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.|
