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

Uwe_Ganswig · October 19, 2016, 1:03pm

Hello everybody, the localization faults seem to be solved after patching the mashine.

Now, the next error.

After adding two more hdds as raid0 pool and apend as a share I would do a samba share. After clicking submit the errorbox comes.

Hi @Uwe_Ganswig can you please post here journalctl -xe

Had a new samba share and it seems ok/not related to locale

Can you please provide systemctl status smb.service too? thx

What happen if you start/stop samba service from Rockstor Web UI?

Flyer · October 19, 2016, 2:08pm

Addendum: had same command on a python shell with env hack and it exited 0 without problems, so not related to new run_command hack

Uwe_Ganswig · October 19, 2016, 3:37pm

Hello @Flyer at this time I’ve a new problem. After install MariaDB, I can’t connect to any service nor webui. And system restore option, tell me, after a short time, that there are no linux filesystems found.

And these errormessage came at start samba too.

I think I must reinstall rockstor and patch it again. Please stay tuned

Thanks for now

Flyer · October 19, 2016, 3:53pm

?? Are you having MariaDB directly over Rockstor??
My suggestion: have it in a Rock-on

Flyer

Uwe_Ganswig · October 19, 2016, 4:30pm

No, I’ve had as Rock-on

Flyer · October 19, 2016, 6:02pm

Ok, wait.
This is related to rock-ons and better to ask other users (@phillxnet, @sfranzen, @bug11 ) having more confidence with rock-ons.

Back to samba / errors / etc:
Is your Rockstor environment ok with patch & without rock-ons?

Mirko

Uwe_Ganswig · October 19, 2016, 6:19pm

Hi Mirko, I’ve a big problem. After fresh install all seem ok.Samba run and shares are working.
After reboot samba give me a shoot in my heart.

If I try to activate SMB under services the known error message comes.

Here the status message

sfranzen · October 19, 2016, 7:07pm

Ok, so SMB fails consistently but for unknown reasons. Could you check if /var/log/samba/log.smbd contains more specific info?

Thx @sfranzen!
Next step: cat /etc/samba/smb.conf

It seems samba doesn’t like your conf file

sfranzen · October 19, 2016, 7:53pm

Getting somewhere! Another useful utility for samba is testparm, it should tell you what is wrong with it.

Flyer · October 20, 2016, 6:01pm

Hei @Uwe_Ganswig,
no news good news?

Uwe_Ganswig · October 20, 2016, 6:29pm

No, Samba will not start. Not in the WebUI and also not at the console.

    log file = /var/log/samba/log.%m

Uwe_Ganswig · October 20, 2016, 7:21pm

In my despair, I have now seen some configuration files.

In the samba_service.py I marked two entries as a comment at the end of the file. Samba is still not started, but the error box does not come anymore

  else:
            try:
                if (command == 'stop'):
                    systemctl('smb', 'disable')
                    systemctl('nmb', 'disable')
                else:
                    systemd_name = '%s.service' % service_name
                    ss_dest = ('/etc/systemd/system/%s' % systemd_name)
                    ss_src = ('%s/%s' % (settings.CONFROOT, systemd_name))
                    sum1 = md5sum(ss_dest)
                    sum2 = md5sum(ss_src)
                    if (sum1 != sum2):
                        shutil.copy(ss_src, ss_dest)
                    systemctl('smb', 'enable')

        return Response()

Flyer · October 20, 2016, 9:03pm

Ok tomorrow going to check systemctl command (maybe missing env)

M.

Flyer · October 21, 2016, 7:26am

Hi @Uwe_Ganswig you don’t have errors because errors are inside systemctl restart eheh
…but having no systemctl smb and nmb don’t restart (that’s why you don’t have samba)

It’s really strange, actually had my dev env out of Active Directory running simple samba and it seems fine. Are you on stable branch or testing branch?

M.

Uwe_Ganswig · October 21, 2016, 7:42am

I don’t know witch branch I use. I use the install.iso from the web side, and so, I think it should be stable.

You wrote, that my settings have no systemctl restart. Should i change

systemctl('nmb', command)  <-- here the first
systemctl('smb', command)  <-- and the second

to

systemctl('nmb', restart)
systemctl('smb', restart)
