Hi everyone,
I've ran into a problem for the second time now after I already considered it fixed.
I have a storage pool (Windows Server 2016, thin provisioning, mirror layout) with one volume and one disk. I deleted the whole thing originally because I couldn't extend it beyond 16TB. I created a pool with 43,7TB and a virtual disk with 20TB and was happy that it worked. However, the last days I've reached about 16,4TB and started to receive in-app error messages when trying to save more data on the volume, programs crashing etc. So, in the end the problem is still there and I have no idea how to solve it. I've tried to create another virtual disk on the pool (4TB) and that worked. So I have the feeling it's not an error with the pool. But how can I make this thing to work with more than 16TB?
A summary on the configuration:
1 storage pool (43,7TB) with 6 Disks (2x12TB, 4x6TB) - ignore the 4TB system and 18TB backup disk.
1 virtual disk (capacity 20TB, allocated 16,4TB))
