we use OnTAP 8.2.4 7-Mode and the newest SLES 12 SP3 but with SMB 2.0 /2.1 we can only use smbclient but not mount.cifs. We get always the problem:
mount error(95): Operation not supported Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
and the kernel reports:
[10999.379311] CIFS VFS: ioctl error in smb2_get_dfs_refer rc=-2 [10999.384622] CIFS VFS: cifs_read_super: get root inode faile
we have opened a SUSE case which mentioned that we get something back from netapp filer which is wrong. Have anybody get it work?
