Yeah, it wen't RO but when I tried to remount I got bad superblock bla bla. And I was unable to fix this by using btrfs repair for example. I'm not sure if it possible to recover from the error I got. That's why I'm concerned about power issues in the future. I've been using ext4 for decades and I don't remember that fatal filesystem crash. Yeah I lost some data due to bad sectors or power loss but I was always able to mount the filesystem. -- Best regards
