MOM fails on start up


Hi einjen,

Yeah i discovered this myself and totally agree this is not a good thing haha.

I have bumped into another small issue but pbs is not working as of yet.

Thanks for your input. :slight_smile:



Thank you for clearing this up for me this is very useful and will look forward to an official release for SELinux.

Until then i will have a look at finding some one from the UK to pester mean while i will keep working on a solution and hopefully post my positive findings in due time.


Hi all,

Wee update for you all and any help would be great.

I can load and start each service individually, example dataservice then the schd…and so on but
when i start pbs.service that fails mega style so i have turned it all off and just run the pbs.service and this is the error im getting the now…

pbs.service - Portable Batch System
Loaded: loaded (/usr/local/libexec/pbs_init.d; enabled; vendor preset: disabled)
Active: failed (Result: exit-code) since Mon 2016-12-05 11:43:11 GMT; 2s ago

pbs_init.d[43397]: Failed to upgrade PBS Datastore

systemd[1]: Failed to start Portable Batch System.
systemd[1]: Unit pbs.service entered failed state.
systemd[1]: pbs.service failed.


I think now the installation is pretty bad. It might be a good idea to
purge the PBS home and reinstall again from scratch.



would you mind telling me your best practice for this so please so you know i have done exactly what you would have done?

yum remove


so i have wiped everything i can find on the current system and reinstalled using the rpm server this time and have slowly gone through it step by step until i hit this error when it asks me to use pbs_habitat to update the database but then gives me this error…

Data service directory from previous PBS installation not found,
Datastore upgrade cannot continue
failed to upgrade PBS datastore

Now the only reason i use this is when i use pbs_ini start it tells me to update and use the pbs_habitat.

Any ideas?


Did you delete /etc/pbs.conf and /var/spool/pbs before you started the installation?


yes i removed everything.
this also happened when i installed it on a fresh build.

I commented out the code last time but this is not a solution but a mere work around which is not what i want to do for every build.
