Could you describe them for the error?

Mayur B

10/31/2023, 10:52 AM

You are deploying it in gke?

Kalman Speier

10/31/2023, 10:53 AM

yes, gke autopilot cluster

Mayur B

10/31/2023, 10:53 AM

Just describe the pods for the error

Kalman Speier

10/31/2023, 10:53 AM

which one?

Mayur B

10/31/2023, 10:53 AM

The one thats crashing

Kalman Speier

10/31/2023, 10:54 AM

Kalman Speier

10/31/2023, 10:54 AM

and what part of the describe is interesting?

Mayur B

10/31/2023, 10:54 AM

Does your cluster has necessary IAM permissions for accessing the storage?

Mayur B

10/31/2023, 10:54 AM

The end part where events are described is fine

Kalman Speier

10/31/2023, 10:55 AM

ok. for example: Events:

I dont see any error here. Any clues from logs?

Kalman Speier

10/31/2023, 10:56 AM

necessary IAM permissions for accessing the storage?

how can i check this?

Im not familiar with gcp, so i dont know how. Maybe you can check with your admin

Kalman Speier

10/31/2023, 10:57 AM

by storage you mean gcp storage classes?

Mayur B

10/31/2023, 10:57 AM

Yes

Kalman Speier

10/31/2023, 10:57 AM

should be ok, i have other apps installed with storage works fine

Kalman Speier

10/31/2023, 10:58 AM

i have a cockroachdb cluster with

premium-rwo

runs fine

Kalman Speier

probably the root cause of the issue is that clickhouse not running?

oh yes, it should be running

Mayur B

10/31/2023, 11:00 AM

Why isnt clickhouse running?

Whats the memory of your cluster nodes?

Kalman Speier

10/31/2023, 11:03 AM

it’s autopilot

probably it’s the resource request for clickhouse in the helm values are not enough

Kalman Speier

10/31/2023, 11:06 AM

but there is no limit set in the yaml, so it should be fine. i don’t know.

Mayur B

10/31/2023, 11:06 AM

https://github.com/SigNoz/charts/blob/main/charts/signoz/values.yaml#L157 Maybe try removing the limits or scale up your nodes

Mayur B

10/31/2023, 11:06 AM

Limits are set i have shared the link

Kalman Speier

10/31/2023, 11:07 AM

limits are commented out. no ?

Mayur B

10/31/2023, 11:07 AM

Oh yea Sorry

Kalman Speier

10/31/2023, 11:09 AM

either way i try to set higher resource requests and will see..

I fixed this by increasing the memory of clickhouse to 2gb
