Hi,
We are currently facing a strange behaviour with our cluster. Right now I’m running bitrot scrub against the volume but I’m not sure it will help finding the problem. Anyway, my question is about nfs-ganesha and NFSv4. Since this strange behaviour begun, I read alot and I found that idmapd is needed for NFSv4. If I run rpcinfo or ps –ef |grep idmapd on our nodes, I don’t see it.
Is rpc.idmapd supposed to be running when using nfs-ganesha 2.6.3 with gluster 4.1.5 ?
IMO rpc.idmap as a service is not required for ganesha, but ganesha uses apis from "libnfsidmap" for id mapping for confirming the same
idmapd is used to convert client usernames/IDs into server usernames/IDs. This allows things like a user with UID 100 on one client to map to the same user with UID 200 on another client. It's not, strictly speaking, necessary; but it's very nice to have, especially in large environments with diverse clients. NFSv4 will work without it. Daniel
