Command Reference: edf startup {pause | resume}
The edf startup pause command flags core HPE Ezmeral Data Fabric on Kubernetes components, such as CLDB and MFS, such that they will to enter
into a nonfunctional state when they restart. The pods resume their startup sequence only after
the edf startup resume command is executed.
Syntax
edf startup {pause | resume}Description
The edf startup {pause | resume} command pauses or resumes the restart of
core HPE Ezmeral Data Fabric on Kubernetes cluster components, such as CLDB and MFS pods.
Parameters
pause-
Pauses the startup of certain HPE Ezmeral Data Fabric on Kubernetes components, such as CLDB and MFS pods. When you
run edf startup pause, there is no impact to a running pod. When one or more pods of this type are restarted (either manually or automatically by Kubernetes due to an issue), the startup sequence for the pod is paused. The pods wait for theedf startup resumecommand to be issued to complete the startup sequence and become functional again. resume-
Resumes the startup sequence of certain HPE Ezmeral Data Fabric on Kubernetes components, such as CLDB and MFS pods. The command does not reboot pods.
Usage
This command must be executed from the admincli pod of the HPE Ezmeral Data Fabric on Kubernetes.
The edf startup pause command is intended for use when troubleshooting
HPE Ezmeral Data Fabric on Kubernetes, in situations where you want the core component
pods to enter into a nonfunctional state when they restart. This command does not stop pods
that are currently running.
To perform an orderly shutdown of a Data Fabric cluster,
see the edf shutdown cluster command.
Use the edf startup resume command to resume normal operations on a
cluster after the edf startup pause or the edf shutdown
cluster command has been executed.
You can check the status of the pods by executing the edf report ready
command.
