Wrong engine displayed in cluster mode

Hi,

I installed arangodb 3.3.4 and I am running a cluster of 3 instances on 3 different machines. At installation time I chose rocksdb as engine and when I run a single server I see the proper engine (rocksdb) on the web UI dashboard. When I use the starter (arangodb and arangodb --starter.join <first_machine>) I see mmfiles as engine on the web UI (also mmfiles when using the API /_api/engine).

In my arangod.conf and /var/lib/arangodb3/ENGINE the engine is rocksdb, as it should be.

can you please help with this?

Thanks in advance

Have you configured all starters with --server.storage-engine=rocksdb when you started them for the first time?

It looks like at least one of the starters did configure mmfiles instead of rocksdb.
