Syncthing seems to think that my btrfs volume is full, but it isn’t. The only way to get the sync running again is to set the Syncthing folder limits to 0. This is the way my drives are setup:
>>> sudo btrfs filesystem df /mnt/btrfs_raid1/
Data, RAID1: total=557.00GiB, used=555.86GiB
System, RAID1: total=8.00MiB, used=96.00KiB
Metadata, RAID1: total=1.00GiB, used=806.94MiB
GlobalReserve, single: total=512.00MiB, used=0.00B
>>> sudo btrfs filesystem usage /mnt/btrfs_raid1/
Overall:
Device size: 7.28TiB
Device allocated: 1.09TiB
Device unallocated: 6.19TiB
Device missing: 0.00B

/dev/sdc1 8.00MiB

Is this a bug or can I configure Syncthing to understand btrfs volumes?
