auto-replicate update

I just updated the auto-replicate script to add in the zfs holds function so that snapshots that have been used to replicate a file system have a hold positioned on them so they can’t be deleted.

It manages the holds so that once you’ve sent a new replication stream to a destination it will remove the old hold and add one to the latest snapshot.

This should obviate the need to deal with missing source snapshots.

Note: you can still break the system by taking snapshots on the destination volume or manually deleting snapshots on the destination. But you shouldn’t be doing that kind of thing anyway…

Migrating stuff

I’m in the process of migrating some of the stuff from the old server which is starting to show its age. In any case the auto-replicate script is now available here. New stuff will show up under the Projects section.
