‘Physical Disk’ name in Storage Spaces RRS feed

  • Question

  • Last week, we replaced a failed disk in our JBOD, with the help of this excellent guide - https://hodgkins.io/replace-failed-disk-in-storage-spaces-pool-with-powershell

    Our situation was slightly different from the scenario in the guide, in that the disk that was replaced was already in a ‘retired’ state. Simply from following the guide, this led us to ask the question – is there an auto setting that controls whether to auto-retire failed disks? We’re running Server 2012 on the SOFS nodes.

    Another thing we noticed, is that the ‘Physical Disk’ name column (when viewing the disks within a pool) in server manager, isn’t always tied to a specific disk. So say for instance, ‘Physical Disk 2’ may be linked to a different disk over the course of a few days. Is this normal?

    Many thanks.

  • Hi MR JH,

    Thanks for your post.

    The default policy for handling a physical disk that goes missing from a storage pool (-RetireMissingPhysicalDisks = Auto) simply marks the disk as missing (Lost Communication), and no repair operation on the virtual disks (storage spaces) takes place, if you're using existing disk capacity instead of a hot spare for virtual disk repairs.

    You could refer to the article below

    It is strange. In normal, it shouldn't point to different disk. Could you please install all the hotfix then have a check.
