[SOLVED] Error running a command. cmd at samba share screen

Flyer · October 21, 2016, 8:25am

this is the meaning of systemctl('nmb', command)

command is a variable with start/stop values, so don’t change it

When you download Rockstor ISO and perform installation it suggests having updates, if you don’t have stable subscription you can add only testing branch updates, have you done it? If not, please do it, perform updates then check again

Hello @Flyer,

nothing changed the situation after updating to version .22

If I click the button to start samba follow error message comes out:

[root@gphomeserver2 ~]# systemctl status nmb.service

Ok, actually failing service is nmb, so can you please provide nmb logs?

/var/log/samba/log.nmbd

Uwe_Ganswig · October 21, 2016, 5:58pm

Hello,

short update. I’ve reinstalled rockstor. Then patched the installation, activated the testing branch updates and installed them. After that I have had to install the patch again.

I hope samba run again after restart.

Uwe_Ganswig · October 21, 2016, 6:08pm

What the hell …

I wanted to change the workgroup name.

Is Active Directory on?

Uwe_Ganswig · October 21, 2016, 6:30pm

No. And it does not matter if samba runs or not.

Flyer · October 21, 2016, 6:53pm

Sorry @Uwe_Ganswig, my fault (and I can’t solve it by now because github is down)

If you can : pls edit opt/rocksotr/src/rockstor/smart_manager/views/samba_service.py
line 72 and change it with adconfig = None

This is a workaround, will patch it asap (@suman pls wait with new release / or patch it if you get github access and no PR from me). Sorry again, my dev env had an ad config field filled or {}, but not Null so I didn’t catch it

M.

Uwe_Ganswig · October 21, 2016, 6:55pm

OK, thanks for now… Hope it works all right after restart

Flyer · October 21, 2016, 7:13pm

Hi @Uwe_Ganswig, got an on the fly test: with that line change setting workgroup works fine, meanwhile github up again

Cooking time, bye

Uwe_Ganswig · October 22, 2016, 8:55am

Hope your food was delicious.

So wtf. Started today the machine, open the webui, open the services and what should i say? Samba does’nt run.

Here are the error message that comes, if I try to activate them:

Good : workgroup working
Bad : nmbd not working

Let’s check it:
cat /var/log/samba/log.nmbd and
journalctl -u nmb.service

Add: are you running a Realtek Nic? I don’t like that r8169, had it on Debian, had it on Centos and always had to move to r8168 (r8169 is a well known buggy one). Here a small howto http://unix.stackexchange.com/questions/108952/realtek-r8169-not-working-in-centos-6-5

Ok, let’s see if the onboard network adapter is the bad boy.

I test it now with a USB network adapter

Uwe_Ganswig · October 22, 2016, 10:33am

Unfortunately, it is not the onboard adapter. Also with the USB-NIC comes the error message.

Ok, can you please post here your etc/samba/smb.conf file?

I don’t think (hope) this to be strictly related to Rockstor code

What if samba starts before network is ready?

sfranzen · October 22, 2016, 11:39am

That’s what I was thinking too, but the problem is I don’t know what the problem is at the moment. It keeps complaining about smb.conf, but I don’t see anything wrong and neither did testparm.

Flyer · October 22, 2016, 11:40am

Nice question: googling found some people having same issue because of samba starting before network is ready. No network -> samba dies

Flyer · October 22, 2016, 11:56am

Does writing smb.conf via Rockstor WebUI kill samba? NO, had it now more than twice without issues
Is workgroup correctly defined via Rockstor ? YES, my last patch.

Related to samba? maybe
Related to samba/nic? maybe

Suggestions: how is your Rockstor network configured? static or dhcp? try moving to static with a dns
checking samba version (smbd --version): my smbd is 4.2.10, you should have same

Another test: try add this to samba configuration (via Rockstor WebUI)
local master = no

We force samba/nmb not to ask to be elected as master browser

EDIT:
pls tail -n 100 /var/log/samba/log.smbd too (shell or Rockstor log manager too )

EDIT 2:
samba custom config, add log level = 10 - you’ll get a f…antastic huge amout of logs, but maybe this will let us better understand both smbd and nmbd
