Samba Service broken after update -11

Hello,
the Samba service is broken after upgrading to 3.9.1-11.

       Traceback (most recent call last):

File “/opt/rockstor/src/rockstor/smart_manager/views/samba_service.py”, line 113, in post
systemctl(‘nmb’, command)
File “/opt/rockstor/src/rockstor/system/services.py”, line 64, in systemctl

It appears that something has disrupted nmb daemon from starting, unfortunately the information in the dialog only tells us that it’s not working, not why.

Assuming you have SSH access configured, or the system shell turned on (System -> Services -> Shell in a box), could you please provide the output for the following commands?

systemctl status nmb.service
journalctl -u nmb,service
systemctl status smb.service
journalctl -u smb.service

Looks like I had a typo, that’s supposed to be a period between nmbd and service, not a comma.
Also, your output appears to be truncated to 80 characters which makes things a bit difficult to diagnose.

Please try the following command again to find out why nmbd is failing:

journalctl -u nmb.service

Finally, it’s possible the config got borked during upgrade. Please provide the contents of smb.conf from /etc/samba. You can use the following:

cat /etc/samba/smb.conf

Thanks again

Hi @Bert,

Looks like you’re missing libwbclient, although I can’t explain why.

Assuming your yum repos are sane, the following should resolve the issue:

yum install libwbclient

If that fails, post results of the following commands:

ls -la /usr/lib64/libwbclient.so.0
yum search libwbclient

Let us know how you get on.

Hi @Haioken,

[root@medienserver ~]# yum install libwbclient

then

  Name and summary matches only, use "search all" for everything.

Strange to say the least - possibly mildly scary.
On mine, the file I looked for appears to be a symbolic link to the same directory, but with a minor version on the end:

libwbclient.so.0.13

This link should be in the package:

[ root@rockout (pass 0s) /usr/lib64 ]# rpm -ql libwbclient
/usr/lib64/samba/libwinbind-client-samba4.so
/usr/lib64/samba/wbclient/libwbclient.so.0
/usr/lib64/samba/wbclient/libwbclient.so.0.13

So, first things first, try reinstalling the package, then (if successful) restart nmb,service

yum reinstall libwbclient -y && systemctl restart nmb.service

If that fails, please check for any possible versions:

ls -la /usr/lib64/libwbclient.so*

If you find one, (which is theoretically libwbclient.so.0.13), you may be able to successfully re-create the link:

ln -s libwbclient.so.0.13 libwbclient.so.0

Substituing libwbclient.so.0.13 with whatever you find.

Hope this helps!

Fantastic. Where the symlink went is a mystery to me, but great to see it back up and running for you!

I appear to run into the same issue, but unfortunately re-installing libwbclient doesn’t seem to work:

Any further ideas?

@Bert, @Haioken, and @doenietzomoeilijk

The update in question that seems to have upset things here would appear to be the system wide shift from upstream that moved our base from CentOS 7.3 to 7.4 around the time that Rockstor 3.9.1.11 was released.
I.e, having just updated a system from Rockstor 3.9.1-10 to 3.9.1-13, samba and co were updated from 4.4.4 to 4.6.2 and initially that caused a failure of the newly upgraded samba to start due to a nmbd failure:

dell1 systemd[1]: Unit nmb.service entered failed state.

However in the above case an:

systemctl restart nmb.service

resulted in nmbd starting successfully and consequently samba also. A reboot would have done the same and a subsequent reboot seems to be functioning as expected, ie prior working samba share still working.

So ‘so far’ I’ve only seen a momentary samba issue related to this system wide update.

@doenietzomoeilijk your log appears to indicate a failure of your system to update, ie you don’t appear to be on the new samba version:

yum list installed samba

the failure of the update is also indicated by the lower version in your links:

ls -la /usr/lib64/libwbclient.so*
lrwxrwxrwx 1 root root 19 Sep 20 14:06 /usr/lib64/libwbclient.so.0 -> libwbclient.so.0.13
lrwxrwxrwx 1 root root 40 Sep 20 14:06 /usr/lib64/libwbclient.so.0.13 -> /etc/alternatives/libwbclient.so.0.13-64

ie this successfully updated machine shows the 0.13 version like @Haioken’s example and @Bert’s successful re-install example.

Which updates release are you subscribed to: testing or stable? I suggest you try and run a system wide update and see what error messages, if any, you see in the logs.

@Haioken Thanks for doing a bunch of the diagnosis here. And yes this is “Strange”. I’m trying a few more systems here that are old enough to be affected and see if anything else sheds light on this.

The full output of the re-install command was a bit long to paste in here (32k text limit), I’ve chucked it in a pastebin here.

I’m on stable. The update was done from within the web UI (which notified me of the update in the first place). What exactly do you mean with a ssytem wide update? A yum upgrade tells me it doesn’t need to do anything. I’m open to suggestions as to how to get this boat floating again (and do some googling on my own as well, since this seems to be more of a CentOS / yum issue than a Rockstor issue).

A little update to my situation, and maybe some background: I’m still in the “trying out if Rockstor is something I want to run with”-phase, and despite the hiccups I’ve run into so far, I’m actually preferring it to the contenders. The reasonably low-overhead, BTRFS-based setup strikes me as a more tenable solution than the tricked-into-working software from a major NAS vendor that shall remain unnamed. Anyway…

The testing is taking place inside a VM on my laptop with a couple of virtual “disk” to horse around with. This means I can easily make snapshots, and since my previous setup decided to throw in the towel yesterday (complained during boot, didn’t show the “data” volumes, after a reboot I could see the volumes but Rockstor didn’t start, etc), I’ve decided to start with a clean slate: I’ve reinstalled on the rocktstor_root (and was subsequently able to re-add my existing data volumes as if nothing had happened, that was a nice surprise). I have not run any updates yet, and I’ve made a snapshot.

So, in order to maybe assist in troubleshooting this issue: what now? I can run the update, I can do all kinds of checks before I do so and afterwards. @phillxnet: What would you have me do?

@doenietzomoeilijk

Thanks for your efforts on this one. Essentially if you could subscribe to the testing channel and then do a Web-UI initiated update and watch what happens as with my tests here I wasn’t able to reproduce the persistent samba issue, ie it would fail to restart directly after the 7.4 related updates but just switching it back on via the services page or rebooting had everything back in place again. However my tests were on updates from Rockstor version 3.9.1-7 and 3.9.1-10 going up to 3.9.1-13. See if your experience is the same as mine this time around, as to address an issue we really need a reliable way to reproduce it.

Thanks again for your testing.

Whenever a new Rockstor package version is detected the update that is run is a system wide one, ie all packages are updated along with the rockstor one. We also have the flashing icon in the top right corner in front of the kernel version in the header that allows for all packages except the rockstor package to be updated. A fancy featured added by @Flyer.

See how you get on as it would be great to narrow down what’s causing these samba restart failures of late. But on the Rockstor code side nothing has really changed on the samba front, hence the suspicion on the upstream updates.

See how it goes.

In my tests I initially setup a pool / share / smb export then did the update to see the effect on the ‘live’ samba.

Yes the pool import seems to work quite nicely, although there are, as always, improvements to be had. Have you seen the related Configuration Backup and Restore feature. That has received some bug fixes of late but also needs more testing / attention.

You’re sure about the Testing channel? I’m fairly sure I was on the regular one before - wouldn’t attempting to update on the same channel be a more trustworthy test of being reproducible? (Currently I’m on 3.9.1-0, btw).

Of course I could try both stable and testing, rolling back to an earlier snapshot in between.

We also have the flashing icon in the top right corner in front of the kernel version in the header that allows for all packages except the rockstor package to be updated.

Ah yes, that’s how I ran the update in the first place. Hit the little blinky icon and OK’d the following dialog. I could try both web-update and regular yum upgrade.

I’ll see if I can grab some time later tonight.

Update: I’ve run the update on the stable channel using the blinky thingy, and it worked properly. Samba was switched off post-install (and during the installation I kept a tail on log messages, and I did see that dreaded SAMBA-4.4.4 not found message whizzing past, but eventually the update was done, and I was able to switch on Samba again.

Things I’ve done differently from last time: I’ve actually sat and waited for the thing to do it’s, er, thing. There’s no real visual feedback when an update is in progress, and I may have interrupted a previous one (not sure if at some point I told the thing to reboot or not, that time - I may have). Maybe there should be some visual clue telling the hapless user that an upgrade is in progress and would they please refrain from mucking with the system, thank you very much. I’m starting to think this may have been a user error, at least on my end.

I have a dump of things yum wanted to go and upgrade, and I have the logs of during the upgrade, if anyone’s interested in them. If need be, I could roll back the snapshot and try an update on the testing channel, for science.

I don’t know whether that’s already on the list of improvements, but I would second this suggestion. I find myself preferring doing a “manual” yum update from SSH rather than using the webUI as this allows me to see what is going on and most importantly when the update is complete.

I’d assume there’s a lock file somewhere while yum is working its magic - in the very least it shows up in the process list a couple of times. Would it be possible for the system to monitor that? Kind of like the current blinky thingy supposedly works? I’m not familiar with how things work under the hood in Rockstor - I’m far too new to it :slight_smile: Also while I know my way around basic Linux things (my work laptop runs Fedora, and I’ve been tinkering with all kinds of *nix boxen for years), I’m not super familiar with how yum or yum-cron works, assuming it’s yum-cron that is used for the updates.

Tiny update: I got a second update after the first one (this time just some Samba stuff). During the update, there was a /var/run/yum.pid present, so that’s definitely something to test for. Samba was still On after the update, everything continues to work splendidly.
