Developer Playgrounds
Developer playground machines are used for developing Ceph.
All machines have cephfs mounts for accessing the teuthology, scratch, and postfile file systems. It is encouraged to use these machines to view teuthology logs as they will be significantly faster than thetext/html2024-11-21T15:42:25+0000Anonymous (anonymous@undisclosed.example.com)faq

Getting Started
This document is geared toward developers and new users of the Sepia lab. It will cover setting up an efficient workstation for use with the lab.
If you haven't already, start by requesting VPN access to the lab. This is necessary for accessing any lab machine or internal service.text/html2026-02-12T18:12:52+0000Anonymous (anonymous@undisclosed.example.com)sidebar

This wiki contains notes on managing and using the “Sepia” lab of test machines used by the Ceph upstream developers.
The target audience for this documentation is administrators and people managing the Sepia machines. If all you need is information on using the lab,text/html2026-04-03T15:12:01+0000Anonymous (anonymous@undisclosed.example.com)testnodeaccess

Testnode Access
Summary
We have about 250 baremetal testnodes that get automatically reserved (locked) and unlocked by teuthology “workers.” Workers are daemons on the teuthology.front.sepia.ceph.com VM that are fed jobs via a beanstalk queue. This page will cover setting up your workstation to lock and unlock testnodes as well as schedule teuthology suites.text/html2022-06-28T14:53:04+0000Anonymous (anonymous@undisclosed.example.com)testnodereimage

Reimaging Testnodes
Summary
mira, smithi, and gibba are automatically reimaged by FOG when locked using teuthology-lock.
Prior to 2018, we didn't have FOG and testnodes would need to be reimaged every so often using cobbler when the OS would get too mangled to re-use. The dhcp server is configured to point smithi and mira to thetext/html2026-02-23T14:22:01+0000Anonymous (anonymous@undisclosed.example.com)vpnaccess

Wireguard Access
Summary
For now, this is a manual process to access the “new” Sepia lab in Poughkeepsie, NY.
How To
Overall flow:
