add ssds to wdqs2003
Closed, ResolvedPublic


This task will be used to coordinate a time between @Gehel and @Papaul to add the new disks to wdqs2003, purchased on T198654.

Adding the disks (not replacing existing) shouldn't result in any downtime, but we should watch it carefully just to be certain. Then @Gehel will need to take over on manually extending the software raid/lvm onto the new disks to use the space.

@Papaul: we'll start by reimaging wdqs2003 (wdqs200[12] to follow). We'll reimage them one by one, to ensure that we have at most 1 host down in the cluster at any time.

@Papaul: ping me when you are around, and I'll depool / shutdown wdqs2003 to let you add the disks. I'll take it over for reimaging and data import.

New SSD in place, server reimaged and data reimported. We're all good!
