Windows cifs share will not mount on startup

Latest response

Hi All, I've got an issue that I know I must be overlooking the simple solution to.

I've setup a cifs share to mount to my RHEL 7.2 system using /etc/fstab, below is the entry in the fstab:

// /mnt/reportshare cifs vers=2.0,credentials=<custom credentials file path here> 0 0

I also added the following line to my /etc/samba/smb.conf file under the [global] sections:

min protocol = SMB2

When the system starts up I consistently get these two lines right at the end of my 'dmesg' output:

[ 32.220097] CIFS VFS: Error connecting to socket. Aborting operation.
[ 32.220320] CIFS VFS: cifs_mount failed w/return code = -115

when I try to troubleshoot with smbclient I get the following output to the listed command:

# smbclient // -U <username here>

protocol negotiation failed: NT_STATUS_CONNECTION_RESET

Finally, when I run "mount -a " as root after startup the Windows share mounts as expected from the /etc/fstab entry.

For the life of me I cannot find a reason why the share will not mount at startup. There has got to be something simple that I am overlooking - any help would be appreciated!


It may be that the mounts are done before the networking is up, maybe add _netdev to the mount options?

Hi Chris, I did try that in earlier attempts but _netdev didn't change anything. I also found a few sources that claimed it only worked with nfs and doesn't help with cifs.

Another option - have a look at adding noauto,x-systemd-automount to the fstab to convert it to an automount filesystem. The systemd-automount man page has a little bit of detail but a google search will probably be more useful.

That did it! I added noauto,x-systemd-automount to my fstab entry and the mount connected after bootup with no errors in the dmesg log! Thank you so much for the suggestion!
