Should probably free this machine for repairs) * test running VMs over NFS with the images residing on ZFS on a thumper (t3fs06?) * migrate all virtual machines to this new installation *DOWNTIME* * File servers and dCache * find solution to upgrade problem %Y% * prepare new Thors for dcache * make standard configuration procedure where puppet takes over most of the config. We cannot do a full puppet host install, since there is no coupling between the JumpStart and puppet * setup raidz2 ZFS structure for the pools * install dCache and bring the Thors online with writes disabled * migrate the data to the new pools to free up servers * Reinstall the old thumpers through Jumpstart, standard config + puppet, so that we have everywhere the same Solaris version and a raidz2 configuration * Migrate dcache to Chimera * Home directories * implement daily snapshots of shome on t3fs06 (cron based script, delete older snapshots) %Y% * implement incremental snapshot transfers to a backup server * Services * convert the VM t3ui02 to a real physical machine (let's take t3wn01) %Y% * Setup a new VM for the VO-Box (mostly phedex... I think that frontier should stay on a phys host with local HD) * Lesser priority * LDAP direcetory service * should we move that onto a VM? Is the admin host indeed a good place for this? backup and failback? This is a critical system * make use of the new extension fields, so that the can be used in automated scripts * Attach system to NAGIOS (maybe a project for a practicum student?)
