Hi Alex,
ok I'll check if there is a problem, but immnd is restartable and should
be restarted after the nid phase is
finished.
After the nid phase the system should be in a "well defined" state.
That was one of the
reasons fifo monitoring was added to the nid phase.

Hi Hans,
I understand. But, what if it doesn't fail in the nid phase?
If you run this command in your setup: "systemctl start opensafd;
sleep 2; pkill -KILL immnd", does immnd get restarted? And does
opensafd successfully come up according to systemd?

Hi Alex,
the reboot should only happen if REBOOT_ON_FAIL_TIMEOUT is set, (i.e.
not 0).
I checked the latest version, the reboot works fine if e.g. immnd
fails in the nid phase and REBOOT_ON_FAIL_TIMEOUT is set.
/Thanks HansN

Hi Hans,
There must be a hole here, then. Because in our setup, if dtmd or
immnd crashes early in the startup process, the node doesn't reboot,
and the executables are not restarted. If I set "Restart=on-failure"
it works fine.
Can you test this in your setup to see if you see the same thing?

Hi Hans,
I just did some tests. Maybe there is a bug in nid, but
when I do not have "Restart=on-failure", the node does not
reboot when I run the command "systemctl start opensafd;
sleep 3; pkill -KILL immnd", and opensafd times out and
fails, with REBOOT_ON_FAIL_TIMEOUT=30.
[HansN] isn't the nid phase finished before the sleep 3 command?
It is only during the nid phase that the REBOOT_ON_FAIL_TIMEOUT
is used,
After the nid phase opensaf enters "normal" operation, no reboot
will be performed as immnd is restartable. Instead of the sleep 3,
you can edit the nodeinit.conf.controller file and change the
immnd line to e.g.
"/usr/local/lib/opensaf/clc-cli/osaf-immndx:IMMND ... " then
nid should fail to start and REBOOT_ON_FAIL_TIMEOUT should work.
But, opensafd restarts every time when I run that command
with "Restart=on-failure" set.

Hi Alex,
a question, if opensafd fails, (assert or exit code ne 0)
a reboot of the node will be performed if
REBOOT_ON_FAIL_TIMEOUT
is configured, I have not checked, but how do systemd
handle the reboot request if Restart=on-failure is set?

systemd enabled [#2839]
Under certain circumstances opensafd fails to start
(immnd or dtmd crashes,
etc).
Apr 19 15:07:31 ams-idsp-46-novnfm osafdtmd[3315]:
src/dtm/dtmnd/dtm_intra_svc.cc:1778:
dtm_process_internode_service_up_msg: Assertion '0' failed.
We can tell systemd to restart opensafd if it fails to start.
