Hosting Hetzner VPS system readonly what to do?

Question

linux

For a couple of years, the readonly system (Debian 2Gb VPS) has already become four times. Moreover, if earlier there was a break of six months, then the last time it took only two weeks between server failures. Attendance is slowly growing, but the trend is alarming.

To restore performance.

umount -a
fsck -C0 /dev/sda
fsck -C0 /dev/sda1
fsck -C0 /dev/sda2
fsck -C0 /dev/sda3
mount -a

What could be the problem and what would you advise me to do?

Answer 1

you most likely have error=remount-ro in fstab
and if there is an error in the file system, it mounts it in Read-Only
You can remount it back using
mount -o remount,rw /
see logs/dmesg for errors.
