A few weeks ago I changed the /home mount to be a direct, rather than an indirect, automount, which means that all of /home is mounted rather than directories for each user. I did this in anticipation of switching to glustefs for homedirs, but specifically I did it in anticipation of enabling pam_mkhomedir. Today I enabled pam_mkhomedir. So, if you log into an instance and your home directory didn't already exist in the project, the instance will create it automatically.
This is one step towards getting rid of the centralized NFS instance, which is really small, causes us performance issues, and often fills up, causing lots of annoying issues. Tuesday night (Oct 30) I'll switch the home directories over to glusterfs storage, rather than the centralized home directories. This isn't an easy switch. I'm going to take the following steps: 1. Change the NFS home directories to be read-only 2. Copy each project's data to its private gluster share 3. Change the autofs information in LDAP to point the /home mount to the private gluster share After doing so, instances will need to be rebooted to use the new mount. Until your instance is rebooted your home directories will be read-only. After all instances are switched off of NFS, I'm going to delete the NFS instance. - Ryan _______________________________________________ Labs-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/labs-l
