Nodepool quota bump

Description

The Nodepool pool tends to be quite busy during peaks hours. Over the last three weeks or so it has been quite noticeable. This task is to raise the pool from 19 instances to 25. New quotas should be:

Instances29
RAM118784 kB
Cores58

details

I got the list of current quotas from labnodepool1001.eqiad.wmnet via:

become-nodepool
nova absolute-limits

Instances are m1.medium: 4GB RAM, 2 CPU, 40GB Disk

MetricCurrent+New
Nodepool max-server19 625
Snapshots22
Quota skew22
Total23 629
OpenStack quotaCurrentNew
Instances23 629
RAM102 400k 16 384k118 784k
Cores44 1458

RAM detail:

  • 102400 kB = 25 instances * 4 GB/inst * 1024kB/GB
  • 118784 kB = 29 instances * 4 GB/inst * 1024kB/GB

This task is to raise the pool from 19 instances to 25

Instances 29

102400 kB = 25 instances * 4 GB/inst * 1024kB/GB
 118784 kB = 29 instances * 4 GB/inst * 1024kB/GB

Is the request here a bump to 25 or 29?

I gave too much details I guess. The request is to bump the quota of instances to 29. That will let us have 25 instances + 2 snapshots +2 extra for potential quota madness.
