Is there currently a way to view and manipulate the chunks? If I understand things correctly, a new fs has a few chunks:
1) System chunk. Contains tree of trees, device tree, chunk tree. 2) Metadata chunk. Contains the directory tree for the default subvol, and any additional subvols/snapshots you create. Directory entries and inodes are in this tree. 3) Data chunk. Files with significant data have blocks allocated from this chunk. The system chunk is always mirrored, even on a single disk. The metadata chunk is mirrored by default, but can be changed with a parameter to mkfs. The data chunk is striped by default, but can be changed via parameter to mkfs. The chunks are all expanded as needed. Is this correct, and is there a way to create a subvol with a new pair of metadata/data chunks and specify how they should be striped or mirrored across what devices? -- 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
