Installing FhGFS-client on CentOS7: helperd does not start upon boot

[Greipel...@mh-hannover.de]

FhGFS 2014.01, CentOS7(RHEL7)

I installed the FhGFS client (fhgfs-helperd and fhgfs-client)on CentOS7
(RHEL7) and everything worked fine. Unfortunately when the system is
rebooted, the fhgfs-helperd is not started automatically. When I checked
with chkconfig --list the helperd and the client are "on". The fhgfs-client
automatically starts up, but of course without the helperd the FhGFS mounts
are not present.
After manually stopping the running client, starting the helperd and
starting the client again, everything is working again.
This procedure repeats with every reboot...
I already installed the client on CentOS 6.5 and SLES11SP3 in the past and
never hat this kind of problems.
Am I missing something important? Any hints?

Hi Joachim,

did you find a fhgfs-client logfile from the start after the reboot?
Contains this logfile some errors?

kind regards,
Frank

Hi Frank,

yes, I know, I should have included this information. This logfile is very
short and concise and contains only one line. It simply states that no
Network Interface Card is found:

(0) Aug19 13:23:22 Main [App] >> Couldn't find any usable NIC

But why? May it be the result of the new "systemd" kind of initialization
introduced in RHEL7, which in this case may have initialized the network too
late? Do you have any hints?

Kind Regards,
Joachim

Hi Joachim,

one problem is a known issues also with other OS which use the Network
Manager. The Network Manager starts the network interfaces only when a
user is logged on. It is required to disable the Network Manager:
$systemctl disable NetworkManager.service
$systemctl disable NetworkManager-dispatcher.service

The new issue is network is disabled by default. Is is required to
enable the network.
$chkconfig network enable

kind regards
Frank

Hi Frank,

Thank you for the answer. Just some minutes ago I found a slightly different
workaround.
If you enable the service "NetworkManager-wait-online" the FhGFS Mount seems
to work OK upon boot:

"systemctl enable NetworkManager-wait-online.service"

For a closer description see
http://www.freedesktop.org/wiki/Software/systemd/NetworkTarget/

Nevertheless I think, this changed behaviour of "systemd" using systems
should someday be taken care of in the packages in the FhGFS repository.

Kind regards,

Joachim

I have kept this thread in mind since Joachim posted it back in August.  So far, despite the fact that BeeGFS Changelog states that there is native RHEL 7 packages for download, they are not using systemd that's the init system of all RHEL and its free rebuilds.  Is there a plan for a minor follow-up release to address this aspect?  Now that even the last hold-out, Ubuntu, has converted from its Upstart to systemd.

Hi Zack,

for us native RHEL7 package means that the source is compiled with the
compiler of RHEL7. If somebody of the community will write systemd
scripts we can add the scripts to the packages.

kind regards,
Frank

Hi,

we have in the meantime reached Version 6.11, but the issue seems still not
fixed. Is there any solution to ensure, that the BeeGFS helperd and client
start after the network is online?

Hi Joachim!

In the meantime, we have concluded that there is no safe
"BeeGFS-internal" way to work around that problem, because each Linux
distribution handles network slightly differently.

Instead we have decided to upgrade our documentation. Before it goes
online though, maybe the mailing list users want to have a glimpse at
the page and tell us if they see any problems with it.

It would be nice if you could have a look at the attached PDF and give
us some feedback!

Kind regards,
Bernd
