- Stores a pool, image name, and snap name triple.
- rbd_locs can be converted to/from strings with the format pool/image\@snap.
- The slash and at signs can be omitted if the pool and snap are empty, respectively.
- Backslashes can be used to escape slashes and at signs in names.
- Examples:
-
- |Pool | Image | Snap | String |
- |------|-------|------|--------------------|
- |rbd | vm | 1 | rbd/vm\@1 |
- |rbd | vm | | rbd/vm |
- | | vm | 1 | vm\@1 |
- | | vm | | vm |
- |rbd | | 1 | rbd/\@1 |
- |rbd\@x| vm/y | 1 | rbd\\\@x/vm\\/y\@1 |
-
- (The empty string should obviously be avoided as the image name.)
-
- Note that the non-canonical forms /vm\@1 and rbd/vm\@ can also be parsed,
- although they will be formatted as vm\@1 and rbd/vm.
