Hello,
All of your Pools and disk-groups are seen as healthy and not in a degraded state. So the drive failure is not currently playing a part in your issue. That being said you should get a replacement drive in the system and assigned as a global spare.
You have 3594.9GB of space allocated and 3594.9GB provisioned. When you disable the over committed feature there is not enough space to move from thinly provisioned to fully provisioned. Which means there is likely some data that is not yet fully committed.
I suggest you add more capacity to your existing disk-groups, allow the over provisioned space to move, and then you will be able to move from thinly provisioned to fully provisioned.
Cheers,
Shawn
