I have the same use case and the same issue with no real solution that I've found. However, mounting nospace_cache greatly reduces the problem. For me the frequency has gone from every other rsync giving No space to about 1 in six, after which I delete some snapshots and start again. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
