Disks

Keeping track of disk drives is almost as much as a headache as keeping track of systems. So here is a tally of disks, currently not up-to-date, but which will be added to as more info comes to hand.

Disks are mounted on spencer, unless otherwise noted.

Notes

  1. This disk has unrecoverable errors and has been decommissioned.
  2. This disk was purchased in Mar 2020, but was found to exhibit numerous disk errors, and was replaced under warranty (during COVID-19 lockdown restrictions!)
  3. Same story. This disk showed numerous disk errors, and is now decommissioned, along with its number. Note: in retrospect, it was a mistake to reuse the disk number. However, since both versions of the disks showed the same behaviour, this no longer seems critical to the nomenclature.
  4. replacement disk for 6007
  5. replacement disk for 6008
  6. Note that this disk is split across two chunk servers (6 & 7)
  7. has an old system (type/version unknown)
  8. keep this disk, has previous ubuntu 18.04
