After restarted the machine of the freepbx the asterisk, sql and all of the services was down.
I checked the journalctl -xe and all services was in Read-Only permission.
I had to umount and mount again the partitions to gain back the read and write permissions and after that I could restart all services and everything worked.
Although now its on air and everything is working properly, every restart to the machine cause the read only problem. what should I do or what do I need to check in order to fix the issue?
