Umount the file system.<br /> # umount /controlM<br /> <br /> 2. Perform a file system check.<br /> # e2fsck -y /dev/mapper/P05TRF1vg-vol_controlm<br /> <br /> 3. Resize the file system.<br /> # resize2fs /dev/mapper/P05TRF1vg-vol_controlm<br /> <br /> 4. Remount the file system:<br /> # mount /dev/mapper/P05TRF1vg-vol_controlm /controlM<br /> <br /> 5. Check if the file system has been resized.<br /> # df -h<br /> <br /> Note: You can refer “man e2fsck” if you want to know more about this command.<br /> # man e2fsck</div>
