Expand description
struct btrfs_util_subvolume_info - Information about a Btrfs subvolume.
Fields§
§id: u64
@id: ID of this subvolume, unique across the filesystem.
parent_id: u64
@parent_id: ID of the subvolume which contains this subvolume, or zero for the root subvolume (BTRFS_FS_TREE_OBJECTID) or orphaned subvolumes (i.e., subvolumes which have been deleted but not yet cleaned up).
dir_id: u64
@dir_id: Inode number of the directory containing this subvolume in the parent subvolume, or zero for the root subvolume (BTRFS_FS_TREE_OBJECTID) or orphaned subvolumes.
flags: u64
@flags: On-disk root item flags.
uuid: [u8; 16]
@uuid: UUID of this subvolume.
parent_uuid: [u8; 16]
@parent_uuid: UUID of the subvolume this subvolume is a snapshot of, or all zeroes if this subvolume is not a snapshot.
received_uuid: [u8; 16]
@received_uuid: UUID of the subvolume this subvolume was received from, or all zeroes if this subvolume was not received. Note that this field, @stransid, @rtransid, @stime, and @rtime are set manually by userspace after a subvolume is received.
generation: u64
@generation: Transaction ID of the subvolume root.
ctransid: u64
@ctransid: Transaction ID when an inode in this subvolume was last changed.
otransid: u64
@otransid: Transaction ID when this subvolume was created.
stransid: u64
@stransid: Transaction ID of the sent subvolume this subvolume was received from, or zero if this subvolume was not received. See the note on @received_uuid.
rtransid: u64
@rtransid: Transaction ID when this subvolume was received, or zero if this subvolume was not received. See the note on @received_uuid.
ctime: timespec
@ctime: Time when an inode in this subvolume was last changed.
otime: timespec
@otime: Time when this subvolume was created.
stime: timespec
@stime: Not well-defined, usually zero unless it was set otherwise. See the note on @received_uuid.
rtime: timespec
@rtime: Time when this subvolume was received, or zero if this subvolume was not received. See the note on @received_uuid.
