       The failed task in the block: "Install fluxtoolkit via helmrelease"

k8s/pods/powerflex/helmrepo-0/nginx_logs.txt:2024/08/28 19:35:30 [error] 27#27: *7 open() "/mnt/helmrepo/flux-toolkit-v0.21.2-29.5bac964.tgz" failed (13: Permission denied), client: 10.43.0.81, server: helmrepo, request: "GET /helmrepo/flux-toolkit-v0.21.2-29.5bac964.tgz HTTP/1.1", host: "helmrepo:30036"

 

Impact 

Unable to deploy PFMP.

Cause

CMO requires UMASK 022 for the proper setup of the Helm charts. UMASK 027 provides root with rwx permissions, the group with r-x permissions, and no permissions for others.

Resolution

Modify the umask values on all three MVM (PFMP) nodes by following this KB - PowerFlex: How to allow different umask values on PFMP hosts | Dell India 

After the values have been modified, reset the PFMP installer, set it up, and initiate the PFMP install, by running the following scripts in order:

# /opt/dell/pfmp/PFMP_Installer/scripts/reset_installer.sh
# /opt/dell/pfmp/PFMP_Installer/scripts/setup_installer.sh
# /opt/dell/pfmp/PFMP_Installer/scripts/install_PFMP.sh
 

The Dell PowerFlex 4.6.x Release Notes, page 18, state the following:

Symptom: The PowerFlex management platform installation process requires that the umask be set to the Linux default (022). If you have changed the default umask setting, the helm images do not have the correct permissions when it comes time to pull the images. 

Recommended action: Change umask to 022.
