Thank you so much for replying.
Actually Trunas does support and use SMB2 & 3 This seems an issue with SME 9 for some reason. I have even turned on SMB1 and NTLM auth, still failing.
*** No backup allowed or error during backup ***
Error while mounting <//10.81.0.5/backup/sme-backup/>
mount error(95): Operation not supported
Refer to the mount.cifs(
manual page (e.g. man mount.cifs)
Oh well, backup to desktop works, so think I will do that and move over to SME10, which is what started me on this mission
