He has plenty of space. What you're describing is the case that either data pool or metadata pool is full, the other has enough space and nothing is left that could be allocated to the full pool. In this case rebalancing would help. But in Tomasz' case there is enough space in every pool, so the allocator should use it. This really sounds like a bug. > But at first you should try to free emty data and meta data blocks: > > btrfs balance start -musage=0 /mnt > btrfs balance start -dusage=0 /mnt Since kernel 3.18 this is done automatically. regards, Johannes -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
