Partition went read-only, how to mount it again?

Question

Every now and then the partition of my Linux installation goes read-only. Since the computer is a laptop, I suppose it's due to some writing error caused by some harsh movement.

Partition was mounted as:

UUID=34h3k4hdf ... /               ext4    errors=remount-ro 0       1

How can I make it rw again without re-booting the system or unmounting and re-mounting the partition?

You may want to check the error by issuing dmesg | grep /dev/sda (if it is sda). — MariusMatutiae, Dec 18 '13 at 17:53

You should be able to simply use

sudo mount -o remount,rw /

What if it shows an error like `write protected`? – adazem009 Feb 09 '21 at 15:20
