Upgrading from v1.6¶
In v1.7 support for CentOS/RedHat 6 has been dropped
Before upgrading to v1.7, please consider the following:
If upgrading from OnDemand 1.3.x or older you must upgrade to 1.6.x before upgrading to 1.7. See directions for upgrading from 1.4 to 1.5 (v1.5 Release Notes) and from 1.5 to 1.6 (v1.6 Release Notes).
As always please update the development or test instances of OnDemand installed at your center first to test and verify before you modify the production instance.
All running PUNs must be restarted after the upgrade due to upgrading to new versions of Passenger and Ruby. It’s recommended to schedule an short outage of your OnDemand instance to perform this upgrade.
Update OnDemand release RPM
sudo yum install -y https://yum.osc.edu/ondemand/1.7/ondemand-release-web-1.7-1.noarch.rpm
sudo yum clean all sudo yum update ondemand
Update Apache configuration and restart Apache.
sudo /opt/ood/ood-portal-generator/sbin/update_ood_portal --force sudo systemctl try-restart httpd24-httpd.service httpd24-htcacheclean.service
Due to changes with
ood-portal-generatorit is necessary to run
--forceflag after upgrading to OnDemand 1.7. The RPM upgrade will generate
/opt/rh/httpd24/root/etc/httpd/conf.d/ood-portal.conf.new. If there are custom manual changes made to
/opt/rh/httpd24/root/etc/httpd/conf.d/ood-portal.confit will be necessary to merge those changes in after running
Force all PUNs to restart
sudo /opt/ood/nginx_stage/sbin/nginx_stage nginx_clean -f
Optionally remove old dependencies from prior versions of OOD if they are not used by other applications.
sudo yum remove rh-ruby24\* rh-nodejs6\* rh-git29\*
Upgrading from v1.5¶
Follow the directions for upgrading to v1.6 first (v1.6 Release Notes). After the upgrade is complete and working, follow the directions above.
Support running OnDemand with SELinux¶
Beta support for running OnDemand with SELinux has been added. Support is enabled by installing the
ondemand-selinux package. For details see SELinux
ondemand-selinux package was installed from the OnDemand 1.6 release there are several changes that must be addressed manually. Several SELinux booleans were enabled by the
ondemand-selinux package and are no longer needed by OnDemand. The following SELinux booleans can be disabled if not used outside OnDemand:
sudo setsebool -P httpd_execmem=off sudo setsebool -P httpd_unified=off sudo setsebool -P httpd_enable_homedirs=off sudo setsebool -P httpd_read_user_content=off
Update project dependencies¶
Drop EL6 and add EL8 support¶
OnDemand has dropped support for CentOS/RedHat 6 and added support for CentOS/RedHat 8.
Added the Linux Host Adapter¶
Support for running jobs directly on Linux hosts has been added. This means interactive jobs can now run on a login node instead of through a batch scheduler.
See the documentation for the LinuxHost. for more details.
Show account balance warnings¶
The dashboard can now show account balance warnings if the users’ account balance is some threshold.
See these docs for more details on how to enable this feature.
Job Composer and Active Jobs match Dashboard Branding¶
The Job Composer and Active Jobs apps’ top navigation bar now share the same branding scheme configured for the dashboard.
There’s no additional configuration required for this other than what’s documented here.
Special thanks to @zooley (Shawn Rice) for implementing this feature!
OOD can be put into ‘maintenance mode’ where it serves a static page to either all users or a subset (staff on a VPN for example). This static page informs users that maintenance is underway while administrators perform disruptive tasks.
See these docs on how to configure and enable this feature.
Documentation for Keycloak as identity broker with CILogon and Keycloak with Duo 2FA¶
Documentation for Keycloak as identity broker with CILogon has been added in the documentation entitled ‘Configure Keycloak with CILogon’.
Documentation for Keycloak with Duo two factor authentication has been updated in the documentation entitled ‘Two Factor Auth using Duo with Keycloak’.
Add Grafana support for ActiveJobs app¶
OnDemand’s ActiveJobs app can display graphs for jobs that are pulled from Grafana. Details on how to configure Grafana support are in these docs.
Improvements to ood-portal-generator¶
The ood-portal-generator app has been rewritten in Ruby and extensive testing added.
Checksums generated for
ood-portal.conf now exclude comments.
Add an ssh wrapper to the shell app¶
An ssh wrapper script can now be used instead of just the
ssh command in the
shell app. See how to configure this here.
Special thanks to @baverhey (Bart Verheyde) for implementing this feature!
Regenerate ood-portal.conf with every apache restart¶
Systemd will now regenerate the ood-portal.conf before every apache restart. This means
administrators can now edit the
ood_portal.yml configuration and then restart httpd
directly without having to do the additional step of running the
Apache httpd will read the new configuration, because a new ood-portal.conf will have been written just before restarting.
However you will have to follow the upgrade instructions (above), and then this will
be available. Specifically updating the ood portal through
sudo /opt/ood/ood-portal-generator/sbin/update_ood_portal --force.
This feature relies on checksums generated by
ood-portal-generator. If the checksums
differ (i.e., ood-portal.conf has been edited by hand, outside of the ood-portal-generator
program) this will fail and you’ll have to force an update through
Support sanitizing job names¶
Administrators can now set the
OOD_JOB_NAME_ILLEGAL_CHARS environment variable to prevent
characters from being used in job names. For example if you do not want to use
/ in job
names (as is the case with some Grid Engine versions) you would
OOD_JOB_NAME_ILLEGAL_CHARS: '/' in the
pun_custom_env attribute of
nginx_clean support for a specific user¶
nginx_stage nginx_clean command now supports a
--user option so it may
kill a specific users’ PUN. For example
nginx_stage nginx_clean -u johndoe would only
kill johndoe’s PUN and disregard all the others.
Dashboard now alerts on malformed cluster configs¶
Prior to 1.7 the dashboard would not start if there was a cluster cluster definition file
(the files in
/etc/ood/config/clusters.d/) that had invalid yaml.
The dashboard now handles this gracefully and shows an error message to the user stating that this file is unusable and should indicate the line of the file that is problematic.
Job composer now shows suggested scripts¶
When changing the job script in the job composer the user is now presented with a dropdown of ‘Suggested Files’ first along with ‘Other valid files’.
Files in folder will be suggested if they match any of these criteria:
Have one of these extensions: “.sh”, “.job”, “.slurm”, “.batch”, “.qsub”, “.sbatch”, “.srun”, “.bsub”
The file starts with a shebang line (#!)
Has a resource manager’s directive (#PBS, #SBATCH, #BSUB or #$) in the first 1000 characters.
Other valid files only have to meet a size requirement of less than
defaults to 65 (meaning 65 kb).
Reduced installation size by 30 percent¶
We reduced the size of the main OnDemand RPM by nearly 40%.
The 1.6 ondemand-1.6.22-1.el7.x86_64.rpm was 162M and in 1.7 this has been reduced by 63M to a total of 99M, split between two RPMs: ondemand-gems-1.7.10-1.7.10-2.el7.x86_64.rpm with 68M, and ondemand-1.7.10-2.el7.x86_64.rpm with 31M. This is in part due to switching to a monorepo at https://github.com/osc/ondemand and installing all the gems into a central shared location, installed using the new ondemand-gems RPM.
The resulting sizes of the two main install directories, /opt/ood and /var/www/ood/apps/sys, were in total reduced by 181M:
$ cat /opt/ood/VERSION v1.6.22 $ sudo du -h -s -x /var/www/ood/apps/sys /opt/ood 592M /var/www/ood/apps/sys 17M /opt/ood
$ cat /opt/ood/VERSION v1.7.10-2 $ sudo du -h -s -x /var/www/ood/apps/sys /opt/ood 172M /var/www/ood/apps/sys 256M /opt/ood
