Zentyal locks during boot
« on: March 20, 2017, 02:45:35 pm »
Hi All,
since this morning, zentyal is completely lock during plymouthd process.

Here's end of boot.log (after waiting 55 minutes)

Code: [Select]
.....
[  OK  ] Started ISC DHCP IPv4 server.
[  OK  ] Started BIND Domain Name Server.
[  OK  ] Reached target Host and Network Name Lookups.
         Starting Cleanup of Temporary Directories...
[  OK  ] Started Cleanup of Temporary Directories.
[  *** ] (1 of 2) A start job is running for Zentyal start/stop task (55min 58s / no limit)

I try some commands
zs dns status
=> [STOPPED]
But I cannot restart dns
zs dns start=> this never ends

Here's the end of zentyal.log :
Code: [Select]

2017/03/20 13:03:14 INFO> DNS.pm:91 EBox::DNS::appArmorProfiles - Setting DNS apparmor profile

DNS problem, Apparmor problem ?
Any idea will be welcome

Thx

Hi,
here's a simple way to reproduce problem

  • do a fresh install
  • select module to install
  • let zentyal apply updates
  • reboot
  • ...

It was apparmor in my case. Try add the following to /usr/share/zentyal/stubs/dns/apparmor-named.local.mas:

Code: [Select]
/usr/lib/x86_64-linux-gnu/ldb/modules/ldb/** rm,
also alter 'Access to kerberos keytab' to '/var/lib/samba/private/dns.keytab rk,'.

There are other modules namely, mysqld ejabberdctl, complaining at boot time.
For mysqld add the following to /usr/share/zentyal/stubs/dns/apparmor-mysqld.local.mas:

Code: [Select]
/sys/devices/system/node/** r,
@{PROC}/@{pid}/status r,

For ejabberdctl:

Code: [Select]
profile su {
/run/samba/winbindd/pipe rw,
}

to /etc/apparmor.d/local/usr.sbin.ejabberdctl

Thanks for reply,
It's not possible for me to test your reply (I've reinstalled everything  :'().

But I think you find the problem.

I identify that apparmor may be the cause, but hard to find a fix.

Thanks
Best regards

Same issue for me, but it starts complaining at BIND and this fix didn't work. I know this is an old dead topic but I'm dead in the water right now.
Rolling back the server to this morning didn't work.

<UPDATE> I had to roll the server WAY back to get it working again. I'm going to have to redo my system.
