Supported Drive Movements

IN THIS ARTICLE 

Outlines the drive movements that Qumulo supports within a cluster

REQUIREMENTS

• Cluster running Qumulo Core

DETAILS

In the course of a cluster's lifetime, you may need to perform testing or complete lab tasks that require the removal and reinsertion of a drive in the same bay or a different slot on a node.

While it is not typically recommended to move drives around in a cluster, the following drive actions can be performed safely if the need arises.

NON-ENCRYPTED CLUSTERS

Remove and reinsert

• A drive can be removed and reinserted into the same slot on a node. If reprotection of that data has not completed, the cluster will reuse what data it can from the drive.

Move a drive to another drive bay within a node

• A drive can be removed and inserted into a drive bay within that node if it is the same drive type. Swapping an SSD with an HDD or SSD data drives (including the boot drive) is not supported. If reprotection of that data has not competed, the cluster will re-use what data it can from the drive.

HPE ENCRYPTED CLUSTERS

IMPORTANT! Due to the nature of the hardware encryption system used on HPE encrypted clusters, drives cannot be moved around. As soon as a drive is removed from a cluster, the drive is immediately failed out and cannot be re-inserted without formatting the drive.

ALL FLASH CLUSTERS

IMPORTANT! Drives in the Qumulo P-series 2U platforms are hot swappable and do not require a power shut down. Operations can continue while the drive carrier is being replaced. Due to the nature of NVMe hot swap technology used in Qumulo P-series all-flash clusters, a drive may not be recognized after swapping. In the rare case that this occurs, reboot the node to complete drive detection.

RESOLUTION 

You should now be able to safely perform supported drive movements on Qumulo platforms
