How to replace a NVME Caching device on a Storage Spaces Direct Cluster

After my initial failure of replacing a NVME Caching card and hitting a bug in the 2016 version i was on, i replaced another one today. As we where starting our cluster out with Intel 750 drives, and these NVME PCIe cards only have 70gb of write’s pr day. So i decided to replace them with the Intel DC P3600. The first failed as can be seen here.

Step 1

Drain the node and Pause it, then shut it down

Step 2

Replace the NVME Card and boot it back up

Step 3

Open PowerShell and type to see the new NVME card.

Now let’s set the old NVME¬†card in Status retired.

This will retire the disk run

Now let’s add the new NVME disk

Now let’s set the disk as Journal drive and see how it looks after. S2D might even do this automaticaly

Now run this command

Now it’s added and you can resume the node. Then pause the node and resume it again and the disks will go out of maitenance mode.

If you run you will see that the retired disk is gone.

After you enable the node again the storage rebuild job will run. This needs to finish before you replace another drive. And you won’t be able to pause a node before it’s finished.
