mount: cannot remount /dev/sda5 read-write, is write-protected

[Delaney martin]

Whenever I tried to read/write my file using: sudo mount -o remount,rw /, I got this error: mount: cannot remount /dev/vda1 read-write, is write-protected. Is there any reason for this?

Run this once in rescue mode to locate root disk : lsblk

Your root partition is probably /dev/sda5 or /dev/vda1.

Run filesystem check (fsck)
Now run:

fsck -f /dev/sda5
Replace /dev/sda5 with your actual root partition from lsblk

reboot Server
Now try:

mount | grep ' / '
