Storage spaces in read only after multiple drive failure, is there any way to repair the storage pool?

Question

Thank you in advance if you're looking at this!

Windows 10 Pro -Version 10.0.19045

I had multiple drive failures in my storage pool, and it is currently read only, I am unable to add disks to it (I have a couple just ready and waiting). 2 of the failed drives may be salvageable, their status is a little confusing; disks 1 and 7 show "{Failed Media, IO Error, OK}" and retired (get-physicaldisk output at the bottom).

the datastore-repair job shows as suspended:
Name IsBackgroundTask ElapsedTime JobState PercentComplete BytesProcessed BytesTotal

---

DataStore-Repair True 02:01:47 Suspended 22 1.88 TB 8.19 TB

The Storage pool has 2 storage spaces in it, one has no resiliency, and is inaccessible, the other does have resiliency, and is accessible.

I have attempted to set the space to read/write via powershell, however it does not seem to work:

PS C:\Windows\System32> Set-StoragePool -FriendlyName "Storage Pool" -IsReadOnly $False

PS C:\Windows\System32> get-storagepool

FriendlyName OperationalStatus HealthStatus IsPrimordial IsReadOnly Size AllocatedSize

---

Storage pool Read-only Unhealthy False False 48.2 TB 37.07 TB

Primordial OK Healthy True False 89.25 TB 70.95 TB

I have removed a couple of terabytes to other storage from the accessible pool in hopes that the repair job could proceed, as but that doesn't have seemed to have helped, as the job isn't starting.

I have also attempted to reset the two drives, and gotten similar results; they stayed in their current state

PS C:\Windows\System32> Reset-PhysicalDisk "WDC WD102KRYZ-01A5AB0"

Hello,

Thank you for posting your query in the community.

It seems that you want to repair your storage pool after multiple drive failures. Here are some things you can try:

First of all, make sure that all f your data is backed up properly. Then follow these steps:

1. Check Drive Status: Use the following PowerShell command to check the status of your physical disks: Get-PhysicalDisk (This will help identify which drives are failed or degraded.)
2. Remove Failed Drives: If you have identified failed drives, you can remove them from the storage pool using:
3. Remove-PhysicalDisk -PhysicalDisks "DriveLetter" (Replace DriveLetter with the actual drive letter of the failed drive.)
4. Replace Failed Drives: If the failed drives are replaceable, physically replace them with new drives. Ensure that the new drives are the same size or larger than the original drives.
5. Add New Drives to the Pool: After replacing the failed drives, add the new drives to the storage pool using: Add-PhysicalDisk -StoragePoolFriendlyName "YourPoolName" -PhysicalDisks "NewDriveLetter" (Replace YourPoolName with the actual name of your storage pool and NewDriveLetter with the letter of the new drive.)
6. Repair the Storage Pool: Use the following command to repair the storage pool: Repair-StoragePool -FriendlyName "YourPoolName" (This command will attempt to rebuild the data on the failed or degraded physical disks.)
7. Check the Status of the Storage Pool: After repairing, check the status of the storage pool again using: Get-StoragePool (Look for any alerts or warnings indicating that the pool is still in a degraded state.)
8. Set the Storage Pool to Read/Write: If the pool is still read-only, you can try setting it to read/write using: Set-StoragePool -FriendlyName "YourPoolName" -IsReadOnly $False (This command should allow you to access the storage pool again.)

Hopefully it will help to repair the storage pool.

Appreciate your understanding and patience.
