Ubuntu 14.04 samba 4.1.6: Errors after upgrading
Hello, i upgraded my ubuntu server from ( i think it was) 13.04 to 14.04 and i had webmin + samba working.
Now, i get tons of errors. i don't use the webmin interface at the moment, rather just trying to find out how to save this mess.
Let's forget for a moment that webmin doesn't seem to work with samba 4 at all.
When ssh-ing and sudo-ing in to the server i get this (official bug it seems) :
Code:
no talloc stackframe at ../source3/param/loadparm.c:4864, leaking memory
Failed to open /var/lib/samba/private/secrets.tdb
tdbsam_open: Failed to open/create TDB passwd [/var/lib/samba/private/passdb.tdb]

Instead of trying to find out what is wrong, perhaps the easiest is to revert to samba 3 ? Or even just reinstall Ubuntu 12.04...
It amazes me that it can be so fragile that you need to feel sceptic every time there is a package update notification...
I hope some one has any thought about this!

If you decide to reinstall it's better to go for 14.04. What you saw could be the upgrade process failing, not necessarily 14.04 nor Samba.

Updates are normally safe. The problem is upgrading.

Not a big fan of upgrades but this is a known bug:

They're workin' on it: https://bugs.launchpad.net/ubuntu/tr...a/+bug/1257186
Get rid of the following package and the memory leak error will likely go away:
Code:
sudo apt-get remove libpam-smbpass
It's a silly package any way since it forces at every reboot the samba password to match the user's local login password.
Re: Ubuntu 14.04 samba 4.1.6: Errors after upgrading
Thanks for your replies so far.
I removed libpam-smbpass and got rid of the "no talloc.." thing. Obviously this problem arised after a upgrade to 14.04, the question is if there is a way to get it working again.
I've reinstalled Samba 4, ditched the old smb.conf file and are now trying to get it working again starting from the default Samba 4 smb.conf file. I'm still not sure if there are more things preventing it from working.
Not sure what to do now since this server is live and hot with users beeing slightly upset at the moment :)
Re: Ubuntu 14.04 samba 4.1.6: Errors after upgrading
Update:
I apt-get purged samba, re-installed and now i get from testparm:
rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)
[...]
Loaded services file OK.
ERROR: cache directory /var/cache/samba does not exist
...and of course there are no cache directory for samba. Where is the directive to look for this cache directory!?
smbstatus gives this info:
/var/run/samba/locking.tdb not initialised
This is normal if an SMB client has never connected to your server.
Time is running out, i think at this point i'll either have to reinstall 13.10 or take a look at the win2008 server price offers...
Re: Ubuntu 14.04 samba 4.1.6: Errors after upgrading
Update 2:
Spamming my own thread here...
So i did (after many different try outs):
Code:
sudo apt-get autoremove samba samba-common
and then
Code:
sudo apt-get install samba samba-common
sudo apt-get install system-config-samba cifs-utils
At least for now, i can testparm and smbstatus with no errors! Will try and manually restore shares now...
Re: Ubuntu 14.04 samba 4.1.6: Errors after upgrading
It does appear you may have some weird hybrid of samba3 and samba4 going on.
You stated you purged samba. Did you mean the samba package itself? /var/cache/samba doesn't come from samba it comes from samba-common.
You might want to make sure there are no samba3 packages and make sure only samba4 packages are present.
If 13.10 worked for you then you could go back to it or you can install 14.04. Not sure why you upgraded a production server but either way you might want to install it in a VBox guest first to test things out before you deploy it.
Re: Ubuntu 14.04 samba 4.1.6: Errors after upgrading
Morbius1,
you might be correct since i did a upgrade to 14.04 and had previously installed most things via Webmin. I'm doing my best to clear everything out but i mean, how far must ones wisdom stretch in order to be able to uninstall Samba? I'm not sure how to find Samba 3 related files and safely remove them only?
Also, i think it's not fair to say that when the system itself promotes an upgrade, the production server has to be cloned and tested in a virtual enviroment in order to see if it [an upgrade] works?
Btw, i'm not sure you read my post #6?
Before i had to leave work, i was still not able to log in to a test share with smbclient. Will try again tomorrow!
Re: Ubuntu 14.04 samba 4.1.6: Errors after upgrading
Update 3:
Still not able to get Samba 4.1.6 to work.
Seems there is an Samba 4.1.7 that might fix these strange bugs, but i haven't been able to compile it to try it out...
https://bugs.launchpad.net/ubuntu/+s...a/+bug/1273447
*EDIT*
I'm able to access a test share with the guest ok = yes directive so hopefully not too far from solving this.
Re: Ubuntu 14.04 samba 4.1.6: Errors after upgrading
Update 4:
I can't for my life understand what is going on. I'm adding directive log level = 10 to smb.conf but it's not it showing up with testparm?
*EDIT*
Found this... Of course testparm doesn't show it: http://unix.stackexchange.com/questi...level-is-samba
