Ifnew_size is not supplied, the whole device is used.DIAGNOSTICSOn successful completion, the status code is 0. A status code of 2 indicates the operation was interrupted by the user. A statuscode of 3 indicates the requested check operation could not be performed because the filesystem is mounted and does not support anonline fsck(8). A status code of 1 is used for other failures.EXAMPLESResize the filesystem on logical volume /dev/vg/test to 1000 megabytes. If /dev/vg/test contains ext2/ext3/ext4 filesystem it willbe unmounted prior the resize. All [y/n] questions will be answered 'y'.fsadm -e -y resize /dev/vg/test 1000MENVIRONMENT VARIABLESTMPDIR The temporary directory name for mount points.
