Can't mount SMB3 share

Post by anfinate » 2019/02/07 16:50:14

Error from mount -a:
mount error(5): Input/output error
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Error from dmesg:
[66942.505834] CIFS VFS: ioctl error in smb2_get_dfs_refer rc=-5
[66942.509034] CIFS VFS: cifs_mount failed w/return code = -2

The windows share an SMB3 share running on a clustered file server. OS: Windows Server 2019
I've been having this issue since the Kernal updated on February 2nd.

Kernal: kernel-3.10.0-957.5.1.el7.x86_64

fstab: //share/somelocation /mnt cifs vers=3.02,credentials=/root/my-cred-file

I have tried different versions, 2.1 & 3.0. No luck.

I have tried different credentials. I get denied whenever the credentials are wrong which means I am able to connect to the server.

Any ideas?
