Samba "mount error(11): Resource temporarily unavailable"

RWallett · 06-30-2010, 07:00 PM

I've been running Samba on Gentoo as a PDC for a Windows XP domain for several years. We are using the IdealX smbldap tools to maintain users, we are storing accounts in OpenLDAP, and everything has been just golden for quite a while. However, for various reasons, we are migrating our servers away from Gentoo and onto Ubuntu 10.04 (64-bit). Unfortunately, replicating our Samba PDC/OpenLDAP backend on Ubuntu is kicking our backsides.

I've got Samba 3.4.7 running. I've got OpenLDAP running. ldapsearch/ldapmodify/ldapadd all work correctly. However, when I try to mount a Samba share on another Ubuntu machine, I get...:

Code:

testuser@testhost:~$ sudo mount.cifs //192.168.4.173/testuser /home/testuser/mnt/testuser --verbose -o user=testuser,domain=MYDOMAIN,uid=1000,gid=1000,netbiosname=testhost,ip=192.168.4.173
[sudo] password for testuser:
ip address 192.168.4.173 override specified
ip address specified explicitly
Password: 

mount.cifs kernel mount options: unc=//192.168.4.173\testuser,ver=1,user=testuser,domain=MYDOMAIN,netbiosname=testhost,ip=192.168.4.173,uid=1000,gid=1000,pass=********
mount error(11): Resource temporarily unavailable
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
testuser@testhost:~$

When I attempt to browse to the share on a Windows XP machine, I get this error:

Code:

\\testserver is not accessible.  You might not have the right permission to use this network resource.  Contact the administrator of this server to find out if you have access permissions.

The specified network name is no longer available.

When I tail the /var/log/samba/log.smbd file on the server, I get...:

Code:

root@testserver:/var/log/samba# tail -f ./log.smbd

Any ideas on what else I can do to troubleshoot? I've consulted the magic Google-ball to no avail, and I'm about out of ideas. TIA!

Additional info:

After doing a little more searching, I wondered if maybe apparmor was causing problems, so I ran...:

Code:

root@testserver:~# sudo /etc/init.d/apparmor stop
 * Unloading AppArmor profiles                                           [ OK ] 
root@testserver:~# /etc/init.d/smbd stop

root@testserver:~# /etc/init.d/nmbd stop

root@testserver:~# ps axu | egrep "(s|n)mbd"

root@testserver:~# ps axu | egrep "(s|n)mbd"
root      5161  0.0  0.0  60652  1924 ?        Ss   09:34   0:00 nmbd -D
root      5170  6.0  0.0  90740  4912 ?        Ss   09:34   0:00 smbd -F
root      5172  0.0  0.0  90740  1688 ?        S    09:34   0:00 smbd -F
root@testserver:~#

Now, when I try to access the share from an Ubuntu client, I get this error:

Code:

testuser@testclient:~$ sudo mount.cifs //testserver/testuser /home/testuser/mnt/testuser --verbose -o user=testuser,domain=MYDOMAIN,uid=1000,gid=1000,netbiosname=testclient,ip=192.168.4.173
[sudo] password for testuser: 
ip address 192.168.4.173 override specified
ip address specified explicitly
Password: 

mount.cifs kernel mount options: unc=//testserver\testuser,ver=1,user=testuser,domain=MYDOMAIN,netbiosname=testclient,ip=192.168.4.173,uid=1000,gid=1000,pass=********
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
testuser@testclient:~$

It's a step in the right direction. Looks like the original problem, "mount error(11)...", has been solved -- or at least identified, since the *correct* solution is to fix the apparmor config. Now I need to fix the "mount error(13)..." problem.
