All home directories have finally been transferred off of PAX and onto RAHU.
With this transition, we applied filesystem quotas to all users, basing the quotas on either the group base quota or the amount of space in use (whichever was greater). These quotas were imported into the Self Service Quota tool. At this point filesystem quotas are live and functional just as they are on KE for e-mail.
With the change, we have also changed the drive mapping in the ECS domain for H: from \\PAX\Homes to \\RAHU\Homes. Although not required for data access, this makes it so that the disk size reported over SMB is the quota size. Home directories are still accessible through PAX in all the ways that they used to be.
We have also added a drive mapping for Z: which connects to \\RAHU\Backup, which is a username based share that connects to the home directory snapshot. This gives users access to the snapshot directly. Snapshots are made shortly before midnight Sunday through Friday nights.
