Service: Continuous integration (target for Jenkins Zuul migration)
scandium.eqiad.wmnet currently has two 160GBytes SSD: Intel SSDSA2M160 (sata, 2.5 inches, multi-level cells, 160GB).
We are going to migrate the CI systems (Jenkins/Zuul) from gallium to scandium and would need more disk space to host the new software and most importantly the Jenkins build history and artifacts.
The partitions are using LVM with:
| Partitions | Raid | Mount point | Size |
|---|---|---|---|
| sda1 sdb1 | raid 1 - md0 | / | 10 GiB |
| sda2 sdb2 | raid 1 - md1 | [SWAP] | 1 GiB |
| sda3 sdb3 | raid 1 - md2 | /srv/ssd | 149 GiB |
300 G disks would be ideal and give us enough room. To accomodate for Jenkins / Zuul we would need to slightly adjust the partitioning scheme:
| Partitions | Raid | Mount point | Size | Note |
|---|---|---|---|---|
| sda1 sdb1 | raid 1 - md0 | / | 20 GiB | Grow from 10 to 30 GiB |
| sda2 sdb2 | raid 1 - md1 | [SWAP] | 1 GiB | |
| sda3 sdb3 | raid 1 - md2 | /srv/ssd | 149 GiB | Shrink to 19 GiB |
| sda4 sdb4 | raid 1 - md3 | /var/lib/jenkins/builds | 200 GiB | NEW, Jenkins artifacts |
Leaving 50 GiB for room to grow a partition (if at all possible) and eventually add a second zuul merger instance (the purpose of /srv/ssd right now).
Additional disk space is a blocker for phasing out the Precise host gallium and moving Jenkins/Zuul to scandium.
