Storage driver compatibility

overlay2 is the only storage driver supported by MCR 23.0, with the exception of btrfs, which MCR supports on SLES.

Note

• A number of unsupported storage driver options that are available in MCR 20.10 are unavailable in MCR 23.0, as Mirantis is moving users away from unsupported configurations.

• The vfs storage driver is available in MCR 23.0 for debugging purposes only.
