Remounting Filesystem as Read/Write
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 /
