hi everyone
I have a very strange problem:
in my fstab there are a number of lines referring to smb servers, all with the same structure:

Code: Select all

//192.168.1.2/data2 /mntpoint2 cifs vers=2.0,noauto,credentials=/etc/.xxx,uid=1000,user 0 0
//192.168.1.3/data3 /mntpoint3 cifs vers=2.0,noauto,credentials=/etc/.xxx,uid=1000,user 0 0
//192.168.1.4/data4 /mntpoint4 cifs vers=2.0,noauto,credentials=/etc/.xxx,uid=1000,user 0 0
....

everything is working correctly: no one is automatically mounted at boot ("noauto" option), and everyone is mounted if I run mount with the "source" syntax:

Code: Select all

mount //192.168.1.2/data2

.. or with the "target" syntax:

Code: Select all

mount /mntpoint2

this is true for all the shares...except for one of them, where:

Code: Select all

 mount /mntpoint4

is working... while:

Code: Select all

mount //192.168.1.4/data4

IS NOT WORKING and gives the following output:

Code: Select all

mount: //192.168.1.4/data4: No such file or directory

if I mount it explicitly (i.e. with the "full syntax", without relying to fstab content), with:

Code: Select all

mount //192.168.1.4/data4 /mntpoint4 cifs vers=2.0,noauto,credentials=/etc/.xxx,uid=1000,user

, it works as well

It seems that, just for this share, the implicit "source" syntax ("mount <source>") fails, while the other syntaxes are working (both the "explicit" one and the "target" one)

I've tried almost everything found on the internet... no success

any idea?
thanks

I don't believe we'll be able to diagnose this from your report, given that it seems this would most likely involve a typo or e.g. non-printing character in /etc/fstab which we are not seeing. I'd suggest making sure from e.g. xxd /etc/fstab that everything looks alright also at the byte level but that's about it. Also; is the "not working" immediate or does it involve a timeout?

updates:

I have double (triple) checked the syntax in fstab, even deleting the row at all and rewriting a couple of times, even copying and pasting the text from the (successful) command from the CLI... no luck
the fstab line MUST be correct, otherwise it should not work both with the implicit "mount --source <address>" syntax and the implicit "mount --target <address>" syntax... while in reality the "mount --target <address>" WORKS!!!
the other lines, related to other servers, have no problem

It seems to me that there is something strange/different in the smb server configuration on server 4, with respect of the same configuration on the other servers.. but I do not understand what.. "testparm" mgives no hints, /etc/samba/smb.conf are absolutely equivalent, same users etc

samba version on server 2: 3.6.3-31a.osstech : no issue
samba version on server 3: 4.4.16 Synology build : no issue
samba version on server 4: 4.2.14-Debian : the one with the problem

for the moment I bypassed the problem by invoking the mount with the --target syntax... but I would really like to understand what's wrong

Have you tried disabling the firewall? I'm a new guy, but most of the issues with the smb config has to do with the firewall rules. Just my 2 cents worth.

Yes, I did... no luck
