[OOD-users] Underlying home directory changes

[Nicklas, Jeremy]

Hi Kevin,

Thanks for the stack trace that helps a lot. Walking through the code it seems there is a bug in the Software Collections rh-ruby22 package that you discovered. Although this bug exists, your installation of Open OnDemand should still work assuming:

- you restarted the per-user NGINX process after you changed all the home directories (try restarting your PUN, or the nuclear option restarting the whole machine)
- from the OnDemand host machine expanding the "~" gives the correct full path to your home directory

Could you confirm these?

I will try an update if you recommend that first (https://osc.github.io/ood-documentation/master/updating/update-infrastructure.html)
Thanks,

Hi all,

We have an existing OnDemand setup (based on 1.0), but recently we changed some of the backing $HOME locations (moved file mounts, etc. e.g. /home changed to /newhome-1)

This seems to generate these errors, which you may have experience with parsing (at least the Ruby part).
