Just a simple question. I'm trying to use a 16GB SDHC card formatted in btrfs, and the system eats about 2GB for its metadata space. When the card fills, the situation is like this: werewolf:/media/home# btrfs fi df . Data: total=13.22GB, used=13.22GB System, DUP: total=8.00MB, used=4.00KB System: total=4.00MB, used=0.00 Metadata, DUP: total=1.00GB, used=58.43MB Metadata: total=8.00MB, used=0.00 I lose about 2Gb wrt ext4. Is there any way to shrink this metadata space ? TIA
