Cyberdelia was VTLUUG's second-generation VM server. It has been replaced entirely by meltdown. It aimed to replace Wood in the medium-term as a host for our more critical services. It is currently running CentOS 6.7.

Dmesg indicates it is a Dell PowerEdge 2900 III with board model of 0NX642[1].

It has 2 4-core Intel Xeon X5450 @ 3.00GHz[2][3], with 48 GiB DDR2 RAM clocked at 667MHz, which are Samsung M395T5160CZ4-CE65 4GiB sticks. For reference: the processor currently (2016 March) goes for about $20 on ebay [4]

It has 4 NICs, support for up to 48GiB RAM, and up to 8 hot-swap SCSI (SAS?) hard drives. The disks are configured with 7 931GiB drives, one 278.9GiB drive, and one 67.8GiB drive. The 7 identical drives are mounted in a ZFS-raid array, the smallest drive has an lvm setup on it, and a boot partition.

The current pool is RAID-Z2, and has a total capacity of 6.31TiB, of which 4.06TiB (64.3%) are allocated (as of 2016 March)

It resides in the CVL ECE Server Closet in Whittemore.

VMs hosted

Cyberdelia has the following:

Storage

The following datasets are configured:

  • /tank/nfs/home - user home directories, available over NFS to VTLUUG machines
  • /tank/nfs/scratch - Temporary unimportant storage. Permissions are 777. No snapshots or backups.
  • /tank/nfs/share - For sharing media between users.
  • /tank/nfs/files - vtluug.org/files
  • /tank/libvirt - VM storage
  • /tank/tahoe - Tahoe-LAFS grid

Deprecation (1/19/2025)

Cyberdelia was rebuilt as an ubuntu machine mirroring Infrastructure:Dirtycow's setup in late-2024 early-2025, with 8x12TB 2x2TB RAID1 root, and 8x1TB ZFS RAIDZ2. Information about this incarnation will be found at Infrastructure:Cyberdelia.

/tank

the following list notes which files/dirs were exfiltrated to cistern. everything that was not already on cistern was copied in some capacity.

  • /tank/nfs/private/ -> /cistern/backup/private.7z
  • /tank/nfs/home
    • all homedirs presumed to be copied already, during the migration.
  • /tank/nfs/scratch
    • /tank/nfs/scratch -> /cistern/backups/tank/nfs/scratch
  • /tank/nfs/share
    • /tank/nfs/share/media/music/mhazinsk/README -> /cistern/backups/tank/nfs/share/media/music/mhazinsk/README
  • /tank/nfs/files
    • /tank/nfs/files/pxedisk.qed -> /cistern/backups/tank/nfs/files/pxedisk.qed
    • /tank/nfs/files/2012/piespy/-> /cistern/backups/tank/nfs/files/2012/piespy.7z
  • /tank/nfs/milton_srv -> /cistern/backups/tank/nfs/milton_srv
  • /tank/libvirt -> /cistern/backups/tank/libvirt
  • /tank/tahoe -> /cistern/backups/tank/tahoe

/

this stuff is almost certainly useless. copied anyway, because it feels unjust to rm it -- some fun could be had poking through it, maybe.

  • /home assumed to be copied to /tank/nfs/home, assumed to be copied to /nfs/cistern/home
  • /root -> /cistern/backup/cyberdelia-old/root
  • /opt -> /cistern/backup/cyberdelia-old/opt
  • /var/log -> /cistern/backup/cyberdelia-old/var/log

if there was anything else, it's gone now. c'est la vie.
