Dell NativeEdge: Recommended Changes for Filesystem Notifications for Orchestrator Deployment

NativeEdge Orchestrator needs a change in filesystem notifications to operate correctly.

Not implementing this change may cause issues with system resources and stop NativeEdge Orchestrator software components from loading.

For example, the following errors can be seen in /var/log/syslog:

cat /var/log/syslog | grep "Too many open files"

Jul 10 23:30:01 user systemd-networkd-wait-online[2229946]: Could not create manager: Too many open files
Jul 11 00:19:33 user systemd[2310112]: Failed to create control group inotify object: Too many open files
Jul 11 00:19:33 user systemd[2310112]: Failed to allocate manager object: Too many open files

NativeEdge Orchestrator requires system changes to allow for a larger amount of open files.

To prevent this issue from occurring, NativeEdge engineering recommends increasing the limits of filesystem inotify parameters.

As documented in the NativeEdge Deployment Guide, in the section Prepare Kubernetes for a NativeEdge Orchestrator deployment

Adjustments to the fs.inotify settings:

fs.inotify.max_user_instances = 1024
fs.inotify.max_user_watches = 1048576

 
Once completed, then run below command to process the changes.
