'''Cronos''' (?? - 2007) was the lab's mail and lists server for a while, before it crashed in November of 2004 due to a hardware RAID controller failure. The cost of replacing the controller with the same model was too high at the time, so a new mail server was implemented. Sadly, there is no data backup of any of mail before November of 2004 - all of it was lost. After the RAID controller issue in 2004, Cronos was fixed and was relegated to hosting AFS files for the lab until retirement in 2007. Backups of Cronos user data are still in AFS, stored at /afs/csl/archive/cronos.

Cronos was a server which used to host the school's mail system, and also used to host nearly all files for the CSL (see cronos (directory)). It was temporarily decommissioned from the email system due to hardware problems, which have since been resolved. Cronos was becoming too old for reliable use, and was decommissioned. It is rumored that Cronos now resides in Lee Burton's lair.

Issues

  • For some reason, only one CPU is recognized by the kernel (possibly only one is recognized by BIOS), though we are using an SMP kernel. Both CPU fans turn on when the box is turned on; not sure what the issue is, yet.
  • The second NIC in cronos is used for a direct connection between cronos and chinstrap, so a crossover cable is needed. A normal cable doesn't seem to be working now, so it seems that cronos and chinstrap don't have internal crossover functionality. Either a NIC with internal crossover capabilities will need to be put in, or a crossover cable must be used.

Notes

  • A few modules must either be built in to the kernel or be loaded on the initrd for cronos to boot properly. Depending on which device you're booting from, you either need dpt_i2o or aic7xxx, and the necessary scsi stuff, as well.
  • Cronos is one of the oldest, if not the oldest server in the machine room.
