Provision Disk Space on PCA Storage Systems for Core Dumps Created By Compute Nodes For Virtual Machines (Doc ID 2272195.1)

Last updated on MAY 26, 2021

Applies to:

Private Cloud Appliance - Version 2.0.1 and later
Linux x86-64

Goal

 A supported procedure for PCA's is required to enable compute nodes to create core dumps of virtual machines to a filesystem other than the default location of a compute node's local filesystem. Typically there is insufficient space on a compute node's local filesystem for this.

 

Note: Virtual Machines should not be enabled for "kdump".
For further information on setting up a virtual machine to capture a core dump, refer to "How To Automatically Generate A Memory Dump When A DomU VM Guest Crashes (Doc ID 1167163.1)"

 


There are a number of ways to resolve this, using either an external ZFS storage appliance, or the internal ZFS storage appliance that is part of the PCA.

For external storage, the options are:

External storage options are not discussed further in this document.

For the internal ZFS appliance - which is a core component of the PCA - the options are:


This document focuses on provisioning for core dumps on the internal ZFS appliance.
