Description of problem (please be detailed as possible and provide log snippests): while installing with i3en.2xlarge instances, default installation is with 3 OSD's (one on each node) while the nodes have 2 NVMe devices, which is waist o storage that already paid.
Hi Avi, Is that a documentation gap? I know we can use the 2 devices in deployment so where the gap is?
Hi Raz, It is a documentation gap, since the doc instruction is for using only one device.
Thanks, Moving accordingly
@orit, can you please provide here the required information to doc team and QE? (here and in the Jira document - https://issues.redhat.com/browse/KNIP-1233)
In Section 1.2.4 "Creating OpenShift Container Storage cluster on Amazon EC2" the instructions and the examples are for a single OSD deployment. we should change them to two OSDs for each i3en.2xl node. The local-storage-block.yaml should have 6 devices listed and the outputs of the get pods, get pv should be updated. In ocs-cluster-service.yaml you need to update the storageDeviceSets count to 2 We need to add a paragraph explaining that has the instance has two disk (that is included in it's cost) we are using both.
Hi, Overall looks good. There are 2 changes need to be made: 1) In chapter 1.2.4. (Creating OpenShift Container Storage cluster on Amazon EC2), the instance type should be mentioned explicitly. So please change: "1.2.4. Creating OpenShift Container Storage cluster on Amazon EC2" To: "1.2.4. Creating OpenShift Container Storage cluster on Amazon EC2 Storage Optimized - i3.2xlarge instance type" 2) I think the part of using 2 devices in each node is not highlighted enough. Please highlight it as explained by Orit in comment #6: (In reply to Orit Wasserman from comment #6) > We need to add a paragraph explaining that has the instance has two disk > (that is included in it's cost) we are using both.
Suggestions from comment #10 have been added: 1.2.4. Creating OpenShift Container Storage cluster on Amazon EC2 storage optimized - i3en.2xlarge instance type And "The Amazon EC2 storage optimized - i3.2xlarge instance type includes two non-volatile memory express (NVMe) disks. The example in this procedure illustrates the use of both the disks that the instance type comes with."
