I hope, that this is the right place for my question. I want to ask if there are any caches by default. In the documentation I found something concerning the MDCache. The most settings there are for the caching of read access and metadata. Unless I am misunderstanding But I want to know, if there is a some cache for write operation. In the end, I would like to know if there is a possibility of data loss due to data cached at the Ganesha layer. As a side note, we are using Ganesha together with GlusterFS

I'm not sure if libglfs does any data caching. > Also, the metadata cache in Ganesha is a write-through cache, not a write-back cache, to metadata is always consistent on the back end.
