.... and apparently it can't trim everything. Or maybe my kernel is just too old. $ sudo fstrim -v / 2258165760 Bytes was trimmed $ df -h / Filesystem Size Used Avail Use% Mounted on /dev/sda6 50G 34G 12G 75% / $ mount | grep "/ " /dev/sda6 on / type btrfs (rw,noatime,subvolid=258,compress-force=lzo) so only about 2G out of 12G can be trimmed. This is on kernel 3.1.4. -- Fajar -- 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
