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 at 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

  W                                  DA        0  Thu Dec 19 11:28:50 2019

  N                                  DA        0  Thu Mar 12 09:54:55 2020

                11523186296 blocks of size 1024. 3135971700 blocks available

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...
