Hi, as wiki say https://btrfs.wiki.kernel.org/index.php/Glossary: A part of a block group. Chunks are either 1 GiB in size (for data) or 256 MiB (for metadata).
Btrfs tools show me that allocated size is not 1GiB aligned, things are changes? I miss something? # btrfs fi df /; btrfs fi usage /; Data, single: total=1.41GiB, used=704.47MiB System, single: total=32.00MiB, used=16.00KiB Metadata, single: total=256.00MiB, used=54.30MiB GlobalReserve, single: total=32.00MiB, used=0.00B Overall: Device size: 4.00GiB Device allocated: 1.69GiB Device unallocated: 2.31GiB Device missing: 0.00B Used: 758.79MiB Free (estimated): 3.03GiB (min: 3.03GiB) Data ratio: 1.00 Metadata ratio: 1.00 Global reserve: 32.00MiB (used: 0.00B) Data,single: Size:1.41GiB, Used:704.47MiB /dev/sda1 1.41GiB Metadata,single: Size:256.00MiB, Used:54.30MiB /dev/sda1 256.00MiB System,single: Size:32.00MiB, Used:16.00KiB /dev/sda1 32.00MiB Unallocated: /dev/sda1 2.31GiB Thanks. -- Have a nice day, Timofey. -- 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
