Hi. You are correct. There must be some hardcoded occurences of nfs-ganesha. I tried creating a new cluster using the ceph nfs cluster create command. I was still unable to create an export using the management interface, still got permission errors. But I created the folder manually and did a chmod 777 on it. I then made the nfs export using the management interface and pointed it at the folder. I am, however, unable to mount the NFS share when specifying only V3 on the export. I noticed you mentioned that NFSv3 is not supported?

So the data pool(s) of your cephfs are also storing your nfs data. The CephFS should already be present which seems true in your case. I'm wondering if the name of your cephfs could be the reason for the failure, maybe it's hard-coded somewhere (wouldn't be the first time), but that's not more than an assumption. It could be worth a try, it shouldn't take too long to tear down the cephfs and recreate it. If you try that you should also tear down the ganesha pool just to clean up properly. The detailed steps are basically covered in [1] (I believe you already referenced that in this thread though), I only noticed that the 'ceph nfs export ls' commands don't seem to work, but that information is present in the dashboard. Also keep in mind that NFSv3 is not supported when you create the share.
