  • You're probably aware of this, but the Samsung 850 series are 'consumer grade' SSDs and as such not recommended by either Microsoft or HP for this use case. Particularly note that non-HP hard drives are known to behave unpredictably in proliant servers. Jun 1 '17 at 9:02
  • yes i'm aware of them being consumer grade Jun 1 '17 at 9:58

Hello from what I am seeing, I assume that your original storage space is corrupt. I would recommend manual rebuilding.

By the way, because of these hiccups with S2D, we don't use it

  • how do i do manual rebuild? and what do u use instead of s2d? May 31 '17 at 17:27
  • does manual rebuild issue any interruption? May 31 '17 at 17:58
  • If you're stuck now you won't rebuild... Get your data to backup destination, devastate your S2D pool, create new one from scratch, create new virtual disk from pool occupying your expected capacity and get your data back from backup destination. Jun 6 '17 at 13:56

Does manual rebuild issue any interruption

You can interrupt manual rebuild, and continue after an hour, for instance. However I can't be sure about S2D proper functioning if you would stop the rebuild prosses.

And what do u use instead of s2d?

If you are building a compact 2-node HA cluster, there are better solutions available on market to ensure storage availability, for example, HPE Store Virtual VSA and Starwind VSAN. They are designed to handle multiple drive failures by utilizing replication along with hardware RAIDs for local redundancy. Both of these solutions in 2-node configurations allow you to lose a whole node plus a pair of drives on the other node and still be up and running.


Transient error could be a few things. Are these the old failed disks or the new one?

If you have replaced one and one. Added the new disk retired the old and let it rebuild inbetween replacing of disks?

Run a get-physicaldisk

Also turn off all vms and take the virtual disks offline and run repair-clusters2d -verbose This will repair s2d setup.

Is your virtual disks onlie bdw? Run a get-virtualdisk

  • these are new one. i just replaced the retired physical disk with new one. i didnt do any manual rebuild Jun 1 '17 at 8:16
  • I added the result of get-virtualdisk and get-physicaldisk Jun 1 '17 at 8:24
  • Have you tried the repair-clusters2d command? Id recomend stopping all vm's that are running when running it. You can use -node to just do it on 1 node. If that does not help, id recomend getting another new disk. And replace only 1 disk untill it's finished rebuilding. Then take the disk you took out. Put it into another computer and run the clear-s2dconfig.ps1 script to clear any S2D config on it. You can get it here tinyurl.com/zndvqd7 Make sure to retire the old disk as well. So when you remove it it will have lost communication. Jun 2 '17 at 2:12
  • Just noticed you are running samsung 850 drives. These do not have power loss protection. This might be the cause of your issues. Id recomend getting some other drives like the samsung sm863 or pm863. Sm863 for better write performance. To use them replace one and one disk. Takes a while but. Jun 2 '17 at 9:11
  • Also you only have 1 virtual disk for hyper converged? Recomended is q virtual disk pr node. Jun 2 '17 at 9:12
