Created attachment 1720264 [details] Screenshot from UI on selecting 3 nodes Description of problem: --------------------------------- Currently, in Create Storage cluster page, if the aggregated CPU <24 and memory is <66 GiB, the creation of storage cluster proceeds. The warning message in the UI is following, which may confuse users that atleast minimal deployment would work and setup would be up. ``` The selected nodes do not match the OCS storage cluster recommended requirements of an aggregated 42 CPUs and 102 GiB of RAM. If the selection cannot be modified, a minimal cluster will be deployed. ``` But ideally, OCS deployment should be blocked and no attempt for minimal deployment should also be triggered in this case. Reason: Some pods would be in pending state and deployment will never succeed, not even minimal deployment(with reduced CPU for RGW, OSD and MDS) Version-Release number of selected component (if applicable): ----------------------------------------------- OCS 4.6 and OCP 4.6 and above How reproducible: ----------------- Always Steps to Reproduce: 1. Create an OCP cluster with worker nodes, say 4 CPU and 16 GB memory. 2. In create storage cluster page, select minimum 3 worker nodes, making sure that total CPU is still less than 24 . 3. Check that we are able to click on create, even though ultimately OCS installation wont succeed and pods would be in pending state due to "Insufficient CPU" Actual results: --------------------- Storage cluster creation proceeds but does not succeed due to Insufficient CPU for PODs Expected results: ---------------------- UI should disable Creation of storagecluster if the aggregated config is less than minimal requirement (1 OSD cluster) Additional info: --------------------- $ oc get pods -o wide -n openshift-storage|grep -v Running NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES rook-ceph-mds-ocs-storagecluster-cephfilesystem-a-898765765brpl 0/1 Pending 0 51m <none> <none> <none> <none> rook-ceph-mds-ocs-storagecluster-cephfilesystem-b-5df979496vppt 0/1 Pending 0 51m <none> <none> <none> <none> rook-ceph-osd-prepare-ocs-deviceset-gp2-0-data-0-xdqbz-mdc2r 0/1 Completed 0 52m 10.128.2.21 ip-10-0-160-43.ec2.internal <none> <none> rook-ceph-osd-prepare-ocs-deviceset-gp2-1-data-0-fp25p-8qm8q 0/1 Completed 0 52m 10.131.0.17 ip-10-0-162-122.ec2.internal <none> <none> rook-ceph-osd-prepare-ocs-deviceset-gp2-2-data-0-cvlp8-qpvpr 0/1 Completed 0 52m 10.129.2.28 ip-10-0-225-47.ec2.internal <none> <none> ---------------------------------------------------- $ oc get pods -o wide -n openshift-storage|grep rook-ceph rook-ceph-crashcollector-ip-10-0-160-43-55d7cf6798-wz6zw 1/1 Running 0 53m 10.128.2.20 ip-10-0-160-43.ec2.internal <none> <none> rook-ceph-crashcollector-ip-10-0-162-122-dff975798-25497 1/1 Running 0 54m 10.131.0.20 ip-10-0-162-122.ec2.internal <none> <none> rook-ceph-crashcollector-ip-10-0-225-47-58c86c4c88-lhnm4 1/1 Running 0 54m 10.129.2.27 ip-10-0-225-47.ec2.internal <none> <none> rook-ceph-drain-canary-ip-10-0-160-43.ec2.internal-7dfdd6cw2m2m 1/1 Running 0 52m 10.128.2.22 ip-10-0-160-43.ec2.internal <none> <none> rook-ceph-drain-canary-ip-10-0-162-122.ec2.internal-6785f4txcdf 1/1 Running 0 52m 10.131.0.18 ip-10-0-162-122.ec2.internal <none> <none> rook-ceph-drain-canary-ip-10-0-225-47.ec2.internal-77f949csnbwk 1/1 Running 0 52m 10.129.2.29 ip-10-0-225-47.ec2.internal <none> <none> rook-ceph-mds-ocs-storagecluster-cephfilesystem-a-898765765brpl 0/1 Pending 0 52m <none> <none> <none> <none> rook-ceph-mds-ocs-storagecluster-cephfilesystem-b-5df979496vppt 0/1 Pending 0 52m <none> <none> <none> <none> rook-ceph-mgr-a-6d6c7b5dcc-2g2lz 1/1 Running 0 53m 10.131.0.16 ip-10-0-162-122.ec2.internal <none> <none> rook-ceph-mon-a-95fc68d88-jf75v 1/1 Running 0 54m 10.131.0.15 ip-10-0-162-122.ec2.internal <none> <none> rook-ceph-mon-b-86497d6d5f-vpjnf 1/1 Running 0 54m 10.129.2.26 ip-10-0-225-47.ec2.internal <none> <none> rook-ceph-mon-c-7f66df684b-gm9lc 1/1 Running 0 53m 10.128.2.19 ip-10-0-160-43.ec2.internal <none> <none> rook-ceph-operator-6f4458c7c7-tv7w8 1/1 Running 0 74m 10.131.0.5 ip-10-0-162-122.ec2.internal <none> <none> rook-ceph-osd-0-544658dc6-mztgh 1/1 Running 0 52m 10.128.2.23 ip-10-0-160-43.ec2.internal <none> <none> rook-ceph-osd-1-5944897dd-bdnr7 1/1 Running 0 52m 10.131.0.19 ip-10-0-162-122.ec2.internal <none> <none> rook-ceph-osd-2-78cf556fb7-b5cfp 1/1 Running 0 52m 10.129.2.30 ip-10-0-225-47.ec2.internal <none> <none> rook-ceph-osd-prepare-ocs-deviceset-gp2-0-data-0-xdqbz-mdc2r 0/1 Completed 0 53m 10.128.2.21 ip-10-0-160-43.ec2.internal <none> <none> rook-ceph-osd-prepare-ocs-deviceset-gp2-1-data-0-fp25p-8qm8q 0/1 Completed 0 53m 10.131.0.17 ip-10-0-162-122.ec2.internal <none> <none> rook-ceph-osd-prepare-ocs-deviceset-gp2-2-data-0-cvlp8-qpvpr 0/1 Completed 0 53m 10.129.2.28 ip-10-0-225-47.ec2.internal <none> <none> [nberry@localhost ocs47-ui-bug]$
