SSD is Opertional Dead or Error in VSAN



Oh shucks, if you are just noticing your available VSAN capacity decreased by an entire disk group then you probably lost a SSD drive in your VSAN cluster.  By design, if a SSD drive dies then the entire disk group goes for a coffee break.  Let’s start off by verifying how clairvoyant I am, time for a heat check.

Browse to the vCenter Web Client, Select your cluster > Manage > Disk Management 

If you see “Dead or Error” under Operational then your SSD is hurting.


I know this part might be painful for most but now you’re on the first step of recovery.  Just know, if you have at least 2 other VSAN hosts then you’re safe.  I’m assuming all your VMs have at least a failure policy of 1 host. Unless you’re the type that enjoys freebasing then none of your were VMs were  hanging around with a failure policy of 0.

From here, remove the disk group by Select the Remove Disk group icon under Disk Groups.



Now that you’ve removed the disk group, you can replace the SSD and recreate the disk group like nothing ever happened.  If you don’t have any SSD drives to replace it with then you may want to take the time to see if the SSD is recoverable.  If the drive is still readable by the host then you might be in luck.  The SSD drive just may have went suicidal on you and just blasted away its own partition table.

I only wish I could yank the SSD drive out and bring it back to life by blowing on it like a Nintendo cartridge.  Bro, I don’t care what you say – Excitebike was the best.
