I have an array that was being decommissioned from production and re-purposed to a test environment. I removed it from the storage pool and... waited. Then I waited. Then I realized it had stalled for whatever reason. There were no network issues and the remaining member has more then adequate storage. 

Regardless, I decided to cancel the process and approach it from a different angle. I cancelled the process only to find that it then stalled at 0% while "cancelling". I received advice from a fellow admin that I should leave it as it could take quite a bit of time. That was several months ago and I can safely assume that this isn't expected behavior.

I'm deathly scared that I'll lose data if I don't approach this properly and these arrays are running critical systems. Can anyone provide any insight or advice? I'm unsure of where to turn or how to proceed.
