RHEL 6 server receiving error mounting CIFS (Windows) share – mount error(112): Host is down

When mounting a CIFS (Windows) share, I’m receiving an error saying the host is down

root@linux:~ # mount /mnt/test
mount error(112): Host is down
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

This is the share in /etc/fstab

root@linux:~ # cat /etc/fstab
//$ /mnt/test cifs _netdev,user=appuser,pass=1234,uid=21376,gid=252,file_mode=0775,dir_mode=0775,domain=windows

I’m running a RHEL 6.9 server

root@linux:~ # cat /etc/*release
Red Hat Enterprise Linux Server release 6.9 (Santiago)
Red Hat Enterprise Linux Server release 6.9 (Santiago)

This problem happened because the storage was upgraded and it is using SMB2. You need to have at least kernel 3.7 to have support for SMB2
SMB shares fail to mount with the SMB2 protocol
