Hi, Something i could not find in the documentation i managed to find: if you mount with compress=lzo and rebalance, is compression on for that filesystem or only a single volume? eg, can i have a @boot volume uncompressed and @ and @home compressed.

It''s per filesystem. however you can change compression of individual files between zlib/lzo using "btrfs fi defragment -c", regardless of what the filesystem is currently mounted with. -- Fajar -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
