CIFS share mount problem in xen 7.2

[masud parvez]

I have a zfs storage in ubuntu 20.04. From this zfs I have created a samba share and trying to mount it xen 7.2 server by below command ,but it shows this error? What is the possible issue?

 

mount -t cifs "//x.x.x.x/mypool_CIFS/VM" -o username=admin /backup
Password for admin@//10.22.255.8/mypool_CIFS/VM:  ********
mount error(95): Operation not supported
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Are you sharing that as SMB1 ? I don't know if they ever got around to SMB2/3 or not.

Yeah, see: https://unix.stackexchange.com/questions/70411/mount-t-cifs-operation-not-supported-but-can-connect-via-smbclient

All in support versions of XenServer/Citrix Hypervisor support SMB3 ISO Shares. The SMB SR has always required SMB3.
