Hello everyone,
I had a problem after trying to make a backup through the admin interface in 2.4, as I can’t find the error I can’t paste it here.
Anyway, the result is that I now have a read only filesystem and I can’t solve it.
I’ve tried mount -o remount,rw /
without success, of course I can’t use fsck since the system is mounted.
I’ve also tried to reboot without success
Here is an excerpt from /var/log/syslog
