For the past week my server has been having issues where the boot partition is switching to read only mode.
I managed to boot into rescue mode and to check the partitions
fsck.ext4 -n /dev/sda1
But it looks like everything is fine
e2fsck 1.42.12 (29-Aug-2014) Warning! /dev/sda1 is in use. Warning: skipping journal recovery because doing a read-only filesystem check. /dev/sda1: clean, 49455/3203072 files, 633065/12799728 blocks
Any idea what's happening or which tests I should do to understand what's going on?
Usually rebooting will work properly for a few days/hours, but that's just a workaround for now...
