Mounting CIFS Shares On C8

CentOS 18 Comments

Hi all,

I’m tearing my hair off trying to understand the difference between C7 & C8
for mounting a cifs FS with fstab

I’m building a Plex media server on C8 and duplicated the fstab entries over from my current C7 installation My data (music & movies) are on CIFS shares on a Synology NAS. The packages cifs-utils samba-client samba-common are installed, up to date etc…

These are my current fstab entries on the C7 box

//192.168.1.200/mp3 /home/plex/Musique cifs user=plex,pass=plex,ro,auto,vers=3.0
//192.168.1.200/videos /home/plex/Vidéos cifs user=plex,pass=plex,ro,auto,vers=3.0

On my C8:

[root@plexvm etc]# cat fstab

#
# /etc/fstab
# Created by anaconda on Fri Apr 3 14:02:23 2020
#
# Accessible filesystems, by reference, are maintained under ‘/dev/disk/’.
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info.
#
# After editing this file, run ‘systemctl daemon-reload’ to update systemd
# units generated from this file.

mount error(2): No such file or directory Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Any pointer would be MUCH appreciated!

Thanks

  • I don’t know the answer, but a thought or three:

    1. the entries for the cifs mounts don’t have the last two fields specified. I dunno if they’re absolutely required, so it may not mean anything.
    2. you might want to experiment with the smbclient tool to see if you can learn anything from its responses when trying to access the remote.
    3. also verify that seliinux is not blocking the access.. I’ve had at least one case in which I spent hours banging my head, only to discover it was selinux and not anything in Samba.

    Good luck!

    Hi,

    starting with the easy bit: (3) selinux is disabled, and F/W is (for the time being) stopped as well

    (2) smbclient can access my cifs shares… no sweat…
    [root@plexvm ~]# smbclient //192.168.0.200/mp3/
    Enter SAMBA\root’s password:
    Try “help” to get a list of possible commands. smb: \> ls
    . DA 0 Sun Mar 29 15:21:54 2020
    .. DA 0 Thu Mar 26 11:28:36 2020
    T DA 0 Thu Jun 20 09:53:40 2019
    W DA 0 Thu Dec 19 11:28:50 2019

    F DA 0 Mon Mar 9 14:08:49 2020
    N DA 0 Thu Mar 12 09:54:55 2020

    11523186296 blocks of size 1024. 3135971700 blocks available smb: \>

    as for (1), if I understand well, the 5th field is optional and it is used to determine if the fs needs to be dumped The 6th field is also optional and controls the fsck. As the fs is remote, I don’t want my C8 box to fsck it That should be ok then…

  • Do the directories /home/plex/Musique, /home/plex/Vidéos and
    /home/plex/Séries really exist on the C8 host?

  • User & pass are present According to the man pages, workgroup is supported I have changed it to domain, but that didn’t change a thing

  • Instead of user=, try username=.  mount.cifs(8) states:

    While some versions of the cifs kernel module accept user= as an abbreviation for this option, its use can confuse the standard mount program into thinking that this is a non-superuser mount. It is therefore recommended to use the full username= option name.

  • That was my initial setup before trying the abbreviations, but anyway:

    [root@plexvm ~]# nano /etc/fstab
    [root@plexvm ~]# cat /etc/fstab

  • What happens when you run

    mount -t cifs //192.168.1.200/mp3 /home/plex/Musique –verbose \
    -o username=plex,password=plex,domain=DERWAEL,ro,auto,vers=3.0

    Regards, Simon

  • Just checking… do the target directories exist? I.e. “/home/plex/Musique”
    ?

  • Then, what I’d try is

    1) With an other directory like /mnt/xxx just to make sure it’s not something with /home that it doesn’t like.

    2) See what it’s doing by running it with strace -f mount…..
