    Storage Spaces 2-way mirror Vanished! RAID 1


    Setup:

    • Windows 10 Pro updated to 20H2
    • 1x 600GB HDD with OS Win 10 Pro, updated to 20H2 - all fine
    • 2x 4TB HDD in RAID 1 two-way mirror using Windows Storage Space -ERROR

    All worked fine for 8 months, but while moving system to a new case, all of a sudden mytwo-way mirror drive has VANISHED & storage pool gives an error saying:

    "Drive or storage pool issues"

    DiskManagement shows that the "OK" disk as Storage Pool, Healthy Storage Spaces Protective Partitionand the other disk doesn't show at all.

    Both 4TB show in Bios

    Both 4TB drives show in Device Manager.
    CrystalDiskInfo shows all drives to be in good condition.

    In an Admin PowerShell prompt I get the following info:


    PS C:\WINDOWS\system32> get-disk

    Storage pool Degraded Warning False False 7.28 TB 5.09 TB



    Possible cause:
    Whilst moving the system to a new case and experimenting with cable routing, I likely hibernated the system and swapped the SATA port that the drives plug into. I'm not sure if this has confused Storage Spaces about the pool?


    Any way to recover this, as it suggests that the pool is "ok"?


    Many thanks

    :)

    Software Raid 1. Can not Add Mirror !

    Solved

    I don't use software raid 1 anymore. Instead setup Storage Spaces (Two-way mirror)

    Software Raid 1. Can not Add Mirror !

    Hi there

    I believe to use mirror / striping in RAID 1 configuration on Windows you need to use Storage spaces - so set the 2 HDD's into a storage space and then you can adjust striping / mirroring.

    Windows Storage Spaces -- Replacing a Failed Disk [Two-way Mirror]

    Thought I'd pass along some testing I recently performed with Microsoft's Storage Spaces on Windows 10. I wanted to see the process of replacing a 'failed' drive in a Two-way mirror. The good news is that it's pretty simple.

    I started out with a Windows 10 Home Desktop with an existing Two-Way mirror. The Desktop computer was configured with three drives -- A single 500 GB SSD hosting the operating system and two identical 1 TB SSDs hosting my data on a Microsoft Storage Spaces Two-way mirror.

    In looking at Control Panel; Storage Spaces... This was the original set-up...


    Storage Spaces 2-way mirror Vanished! RAID 1 [​IMG]


    From here I simulated a disk 'failure' by disconnecting one of my 1 TB SSD's [SamsungSSD2] from my Desktop's motherboard SATA port. This created a 'Notification' about the Storage Space


    Storage Spaces 2-way mirror Vanished! RAID 1 [​IMG]


    Although now 'missing' SSD2, the Storage Space could still be accessed normally thru Explorer and you could read/write files as needed without any problems. No changes were evident in Disk Management either.

    Now on to installing a replacement drive. In my case a duplicate SSD which I had available for this 'test'.

    In looking at Control Panel; Storage Spaces you can see that the Desktop computer was operating with a 'Reduced Resiliency' Two-way mirror Storage Space. With the specific problem being 'SamsungSSD2'


    Storage Spaces 2-way mirror Vanished! RAID 1 [​IMG]


    At this point I attached the replacement SSD to the computer followed by selecting 'Add drives' in Manage Storage Spaces


    Storage Spaces 2-way mirror Vanished! RAID 1 [​IMG]


    Storage Spaces automatically found my replacement drive which I added to the Pool. Manage Storage Spaces reflected the increased Pool capacity due to the added drive which it recognized with a status of 'OK'

    Need to clean-up the configuration by deleting the failed SamsungSSD2 disk from the Two-way mirror Storage Space.


    Storage Spaces 2-way mirror Vanished! RAID 1 [​IMG]


    Manage Storage Spaces is now showing the 'new' configuration with SamsungSSD1 and the replacement 'Samsung SSD 860 EVO 1TB' Physical Drives


    Storage Spaces 2-way mirror Vanished! RAID 1 [​IMG]


    Now we're off and running with a repaired Two-way mirror and our replacement drive
