Script to sequentially defrag remote servers (example: on a SAN!)

Previous years i had running several scheduled tasks on all my servers.

Recently I migrated all my Physical Large Iron Hardware (mostly servers) to Virtual Servers (VMs) in XEN. I have an OpenFiler SAN which hosts all the Storage (iSCSI storage or NFS shares).
I still had all my scheduled tasks running at all the Virtual servers, which included Backup and Defrag tasks, they all started somewhere between 02:00 and 06:00 during the night.

Because the defrag and backup tasks were now running all on the same OpenFiler SAN and all at the same time, the SAN was getting a bit slow,… as you can imagine ;)

That’s why i made a sequential defrag script!
