RMD bootstraping fails.

1. Additionally change in golang version upgrade to go1.13.14 in openness configuration required.
2. I also see mismatch in code vs rmd-pod.yaml. /etc/rmd/rmd.toml: sysresctrl = "/sys/fs/resctrl"

rmd/src/utils/proc/proc.go … 63 // IsResctrlMounted Checks if ResCtrl is mounted and if the path is valid 64 func IsResctrlMounted(flag string) bool { 65 f, err := os.Open(Mounts) …
263 //check if resctrl is mounted 264 isresctrlenabled := IsResctrlMounted(ResctrlPath) 265 if isresctrlenabled != true { 266 fmt.Println("Resctrl mount or Mount path failed:", isresctrlenabled)

rmd-pod.yaml … volumeMounts:

• mountPath: /sys/fs name: resctrl volumes:
  • name: resctrl hostPath: path: /sys/fs

Mounting resctrl didn't help. mount -t resctrl resctrl /sys/fs/resctrl

Hi @discoveravis ,

This problem because of the mount issue can be resolved by doing below workarounds.

1. Run the cleanup script first.

2. Append rdt=l3cat to the correct grub config on the node. (openness-experience-kits/group_vars/edgenode_group/10-default.yml ). _default_grub_params: "default_hugepagesz={{ hugepage_size }} hugepagesz={{ hugepage_size }} hugepages={{ hugepage_amount }} inteliommu=on iommu=pt rdt=l3cat"

3. Addition of resctrl /sys/fs/resctrl resctrl in /etc/fstab (for fixing the mount issue)

cat /etc/fstab

resctrl /sys/fs/resctrl resctrl

Please let me know if this fixes your issue.
