@lidw 

Thank you for the logs and required outputs. I suspect we are unable to write to the persistent volumes for catalog, grafana , job.

Troubleshooting & Analysis:-

  • Can see persistent volume claims were created 
  • Following errors were seen in the pods which are in crashloopbackoff 

Errors -

Catalog Pod:- 

"cause":{"message":"mkdir /mnt/k10state/kasten-io/catalog: permission denied"}}}

 

Grafana Pod:- 

chown: changing ownership of '/var/lib/grafana': Operation not permitted

 

Jobs Pod:- 

"cause":{"message":"failed to create directory for store","function":"kasten.io/k10/kio/modelstore.(*ModelStore).openDataStore","linenumber":718,"file":"kasten.io/k10/kio/modelstore/store.go:718","cause":{"message":"mkdir /mnt/k10state/kasten-io/jobs: permission denied"}}

 

Next Steps:- 

Can you check from Isilon side if you are able to write to the directories where this Persistent Volume Claim Exist ?

Regards

Satish

@Madi.Cristil might need to move this to Kasten board for help.

@lidw 

Thank you reaching out to us . 

There are multiple reasons the pods are in failed condition. To troubleshoot more , we need to look at the debug logs. Can you upload them here or if you would like you can open a free trail support ticket and upload the logs to it . so we will have a look 

Command for Debug Logs:- 

curl -s https://docs.kasten.io/tools/k10_debug.sh | bash;

 

Thanks
Satish

@lidw 

Thank you for the logs and required outputs. I suspect we are unable to write to the persistent volumes for catalog, grafana , job.

Troubleshooting & Analysis:-

  • Can see persistent volume claims were created 
  • Following errors were seen in the pods which are in crashloopbackoff 

Errors -

Catalog Pod:- 

"cause":{"message":"mkdir /mnt/k10state/kasten-io/catalog: permission denied"}}}

 

Grafana Pod:- 

chown: changing ownership of '/var/lib/grafana': Operation not permitted

 

Jobs Pod:- 

"cause":{"message":"failed to create directory for store","function":"kasten.io/k10/kio/modelstore.(*ModelStore).openDataStore","linenumber":718,"file":"kasten.io/k10/kio/modelstore/store.go:718","cause":{"message":"mkdir /mnt/k10state/kasten-io/jobs: permission denied"}}

 

Next Steps:- 

Can you check from Isilon side if you are able to write to the directories where this Persistent Volume Claim Exist ?

Regards

Satish

@Satish  Through the storage manufacturer's after-sales optimization and adjustment, it is indeed the storage volume permission problem, we have solved it, thank you
