Remounting Filesystem as Read/Write

From OESF

Remounting Filesystem as Read/Write or Read Only

Some partitions/file systems such as / cannot be unmounted. Some are also mounted as read-only. In order to modify the files on those file systems, you need to remount them as read/write and then remount them back to read-only after you have done what you wanted.

To remount as read/write:

• mount -o rw,remount /

To remount as read only:

• mount -o ro,remount /
