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?

Ämne: [PATCH 1/1] nid: restart opensafd on failure when 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.
