About once a week, or so, I'm running into the above situation where FS seems to deadlock. All IO to the FS blocks, there is no IO activity at all. I have to hard reboot the system to recover. There are no error indications except for the following which occurs well before the FS freezes up: BTRFS warning (device dm-3): block group 78691883286528 has wrong amount of free space BTRFS warning (device dm-3): failed to load free space cache for block group 78691883286528, rebuilding it now Do I have any options other the nuking the FS and starting over?
Unmount cleanly & mount again with -o space_cache=v2. -h
