I wanted to check if is the same issue I have, e.g. with 4.14.1 space_cache=v2: [153245.341823] BTRFS: error (device loop0) in btrfs_run_delayed_refs:3089: errno=-28 No space left [153245.341845] BTRFS: error (device loop0) in btrfs_drop_snapshot:9317: errno=-28 No space left [153245.341848] BTRFS info (device loop0): forced readonly [153245.341972] BTRFS warning (device loop0): Skipping commit of aborted transaction. [153245.341975] BTRFS: error (device loop0) in cleanup_transaction:1873: errno=-28 No space left # btrfs fi usage /media/backup Overall: Device size: 49.60TiB Device allocated: 38.10TiB Device unallocated: 11.50TiB Device missing: 0.00B Used: 36.98TiB Free (estimated): 12.59TiB (min: 12.59TiB) Data ratio: 1.00 Metadata ratio: 1.00 Global reserve: 2.00GiB (used: 1.99GiB) Data,single: Size:37.70TiB, Used:36.61TiB /dev/loop0 37.70TiB Metadata,single: Size:411.01GiB, Used:380.98GiB /dev/loop0 411.01GiB System,single: Size:36.00MiB, Used:4.00MiB /dev/loop0 36.00MiB Unallocated: /dev/loop0 11.50TiB Note the global reserve being at maximum. I already increased that in the code to 2G and that seems to make this issue appear more rarely.
