Consider the following recommendations for the Dell PowerFlex CSI driver installation for Azure:
- Make sure volume snapshot CRDs (Custom Resource Definitions) and volume snapshot controllers are installed irrespective of the number of CSI drivers that are installed in the cluster.
- The PowerFlex CSI driver pods evict once the ‘root’ and ‘/var’ file system hits its eviction threshold of 85%. Make sure to expand the ‘root’ and ‘/var’ partitions for Azure Linux VMs with more disk space to resolve “DiskPressure” on the node.
