Hello, I have a CephFS running on v14.2.8 correctly. I also have a VM which runs Samba as AD controller and fileserver (Zentyal). My plan was to mount a CephFS path on that VM and make Samba share those files to a Windows network. But I cant make the shares work as Samba is asking to mount the CephFS resource with "user_xattr" mount option, which the kernel driver doesnt support. Besides that, looks like I cant set CIFS permissions on directories/files in CephFS because extended attributes are not supported. Is that the expected behavior or am I overlooking something? Looking for information about this issue, I have read about ceph-vfs and Samba CTDB. Are those options really necessary to get Samba over CephFS with CIFS/AD domain permissions? Thanks a lot. Victor.
