https://bugs.launchpad.net/bugs/2023983 Title: btrfs scrub leads to an readonly filesystem Status in linux package in Ubuntu: New Bug description: During an automatic btrfs balance (triggered through an btrfs maintenance timer) there happens a Enospace error. The next automatic "btrfs balance" step leads afterwards to an kernel error (BTRFS: Transaction aborted (error -28)) and a readonly filesystem. The system must be rebooted to get a writable filesystem. A scrub doesn't show any erros. After canceling the paused balance a new manual full balance could be successfully executed. In the attached syslog file there are the extract of the balance process with the kernel stack trace of a 5.15.0-72-generic kernel. I've seen on other systems (with former kernels of Ubuntu 22.04 LTS) these problems with readonly filesystems after btrfs balancing.
