I’m running Bazzite, which is immutable, so the root filesystem is read-only, but I’ve been having an issue pop occasionally where the rest of my filesystem, including my home folder, becomes non-writable. I can’t do much, and constantly get popups about folders being non-writable until I reboot, and then everything goes back to normal.
Does anyone know what can cause this to happen? And is there a way to deal with this without rebooting when it does happen? I don’t know when I’ll be able to try anything out since it’s not a frequent issue, but it has happened to me several times in the past.


I had the same happen on the root folder on a SATA SSD. The SSD was dying (don’t remember if there was SMART errors, but the dmesg log showed write-errors. I cloned old SSD to a new SSD and haven’t seen the problem since. That was years ago.
When there are multiple consecutive write errors, Linux will re-moumt the partition as read-only to protect the data. (There usually a statement along the lines of “on-error:remount-ro” for the partition in the
/etc/fstabfile)
