Hi Ted, Hi Andreas, hi all, On a testsystem (spare laptop) with ext4 as root filesystem sometimes the system starts to return ENOSPC to all write/create syscalls. Sometimes the system runs without problems, at other times it starts having problems soon after boot. A reboot resolves the problem temporarily. I don't see a specific usage triggering the problem. Deleting some files sometimes allows the creation (just touch $unused_filename) of some files, but not many. Anything I can do to help you to debug the problem?
