Infrastructure:Cyberdelia (VM Host)
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.

Deprecation (1/19/2025)

/tank
the following list notes which files were exfiltrated to cistern. everything that was not already on cistern was copied in some capacity.
- /tank/nfs/private
- /tank/nfs/private/ -> /cistern/backup/private.7z
- /tank/nfs/home
- all homedirs presumed to be copied already, during the migration. if this turns out to not be the case, and there's something super important here, feel free to rebuild the zpool from the old disks.
- /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
