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.
