You are correct, our cluster is ceph backed, though we’re not using vfs_ceph, but a kernel mount instead.
Removing the parameters doesn’t change anything on our test cluster, which is running the same samba issue and experiences the same issue.

We did initially test vfs_ceph, but decided not to use it.

I posted a debug (smbstatus -a -d10) here: https://gist.github.com/jeinwag/e5831526749226a4c710a0c60b572ebf

Looks like it's trying to communicate with ctdbd, but is failing?
