--------------------------------------------------------------------------------
1 | The underlying design of BTRFS data structures allows a lot of flexibility and
2 | making changes after filesystem creation, like resizing, adding/removing space
3 | or enabling some features on-the-fly.
4 |
5 | * **dynamic inode creation** -- there's no fixed space or tables for tracking
6 | inodes so the number of inodes that can be created is bounded by the metadata
7 | space and its utilization
8 |
9 | * **block group profile change on-the-fly** -- the block group profiles can be
10 | changed on a mounted filesystem by running the balance operation and
11 | specifying the conversion filters (see :doc:`balance`)
12 |
13 | * **resize** -- the space occupied by the filesystem on each device can be
14 | resized up (grow) or down (shrink) as long as the amount of data can be still
15 | contained on the device
16 |
17 | * **device management** -- devices can be added, removed or replaced without
18 | requiring recreating the filesystem (mkfs), new redundancy options available
19 | on more devices can be also utilized by rebalancing

1 | Custom ioctls
2 | =============
3 |
4 | Filesystems are usually extended by custom ioctls beyond the standard system
5 | call interface to let user applications access the advanced features. They're
6 | low level and the following list gives only an overview of the capabilities or
7 | a command if available:
8 |
9 | - reverse lookup, from file offset to inode, as command :command:`btrfs inspect-internal logical-resolve`
10 |
11 | - resolve inode number to list of names, as command :command:`btrfs inspect-internal inode-resolve`
12 |
13 | - tree search, given a key range and tree id, lookup and return all b-tree items
14 | found in that range, basically all metadata at your hand but you need to know
15 | what to do with them, the ioctl is privileged as it has full access to all
16 | filesystem metadata
17 |
18 | - informative, about devices, space allocation or the whole filesystem, many of
19 | which is also exported in :file:`/sys/fs/btrfs/`
20 |
21 | - query/set a subset of features on a mounted filesystem
22 |
23 | Programming documentation of the ioctls is in the manual page
24 | :doc:`btrfs-ioctl`.
