Ah, this is because shared volumes (both home and project) were turned off in the project settings. We're going to have shared volumes for everyone in eqiad but that setting is still observed by some of the scripts.

I'm not sure what the proper general fix is, but in the meantime your project should be all set.

My feeling is that this is more a bug in the labsvagrant role.

If the labsvagrant class is broken then this should maybe have its own bug, or needs to be taken up with the people who wrote that class (yuvi and/or matanya). This doesn't look like a failure of eqiad, although it may have to do with the way the nfs /home share is set up.

My best guess is that this was caused by the intermittent problem of the NFS server making shared read-only due to a race in application of ACLs. Coren knows about this problem and is trying to track down it's root cause. It seems to be cache related and will typically clear after a reboot or a 10-15 minute wait.

There was a related problem that the NFSv4 server in eqiad is enforcing idmapd identities and the NFS server didn't know about the locally created vagrant user. Coren has fixed this by adding a vagrant user to the eqiad LDAP.

You may have to create the /home/vagrant directory manually at this point. This may be something that needs to be fixed in the labs_vagrant role.

In fact I had to create the /home/vagrant directory manually and fix permissions. Thus, I do not see the bug as fixed.
