storage spaces direct - virtual disk repair error

Question

Hello! We have s2d cluster with 4 nodes. After reboot one node - some off virtual disks was degraded operational and health status.

When we try start repair virtual disk manual - received error

And see suspend storage-jobs

But all PhysicalDisks in storage pool is ok

I think that this error is due to the fact that the free space on the storage pool is less than 20%, since restarting the node 2 weeks ago, when the free space on the storage pool was more than 20%, there was no such error

Please tell me how you can solve the problem without adding physical disks or removing virtual disks

Answer 1

Hi,

restarting the node 2 weeks ago, when the free space on the storage pool was more than 20%

Just curious about why restart node 2 makes the free space on the storage pool more than 20%? Do you mean restarting freed up some space?

As far as I'm concerned, firstly, we need to check if the error is due to the 20% free space, please check when the issue occurs, does the S2D meet the Fault tolerance:

https://learn.microsoft.com/en-us/windows-server/storage/storage-spaces/storage-spaces-fault-tolerance

If the issue is really due to that we need to have 20% free space while the S2D is running out of space, I'm afraid to say if we don't have more slots, we are unable to add space to the space pool.

Thanks for your time!
Best Regards,
Anne

No, I mean that 2 weeks ago there was more than 20% free space in the storage pool, and when I rebooted node, I did not have such problems. In any case, the
version about 20% free space was wrong. New information:
At last week i delete one of virtual disk and after run command Get-StoragePool S2D | Optimize-StoragePool, virtual disks with warning health status was repairs.

But wow we have more 35% free space in storage pool but i have a same problems after rebooted another node.

All nodes up

All disks ok and healthy

We don't understand what's going on, please help us

All nodes have the same disks configuration
2 nvme and 22 hdd

Also i find errors 300, 301 on node which own storage pool :
