> Local recovery with RocksDB fails if the state storage directory is not on
> the same volume as RocksDB's working directory. The reason is that the
> {{RocksDBHandle}} only tries to hard link the RocksDB files when calling
> {{restoreInstanceDirectoryFromPath}}. If hard linking is not supported, then
> the operation fails.
> In order to harden this behaviour, I suggest to fall back to copying the
> files over if hard linking fails.
