jenkis-deploy user on labs should have its home in /mnt
Closed, ResolvedPublic

Description

The Jenkins slaves on labs projects (deployment-prep and integration projects) use the user jenkins-deploy to setup the instance as a Jenkins slave. The LDAP entry points the home of that user to /home/jenkins-deploy which is a GlusterFS partition for the integration project.

The slave jobs are run under /mnt/jenkins-workspace since we don't want the jobs workspaces to be on a shareable disks to avoid obvious race conditions.

To avoid relying on GlusterFS, we should get jenkins-deploy home to point to /mnt/jenkins-deploy . That needs some puppet change to create the home directory then the LDAP entry can be altered.

All instances now have a /mnt/home/jenkins-deploy homedir which belong to jenkins-deploy.

The next step is to have the jenkins-deploy user home dir to be updated in LDAP to point to /mnt/home/jenkins-deploy

Currently:

  1. ldaplist -l passwd jenkins-deploy|grep homeDirectory

homeDirectory: /home/jenkins-deploy

Then reconnect all Jenkins slaves and make sure jobs can still be triggered.

Apergos reviewed the puppet changes and Andrew updated the homeDirectory.

I have rebooted most slave instance (beside deployment-parsoid2 and deployment-bastion).

integration-slave01 Jenkins slave has reconnected and the npm command now use /mnt/home/jenkins-deploy for its cache thus solving the issue I had.

Still have to double check the other jobs/slaves.

I have disconnected and reconnected all slaves. Bye bye GlusterFS.
