I have a pair of exchange 2013 database servers running in a DAG on a vmware cluster. I have plenty of transaction log and mailbox database space available (dedicated iSCSI Luns mounted to the servers for these drives) but the problem is that my C: OS drive was created when space was tight. I want to expand this volume (its using 59gb of 70 approx) and ive cleaned up installation files from IIS etc but thats just a band-aid.
My question is this: I can expand this OS Volume if i convert it from basic to dynamic and its pretty simple. ive actually been able to clone my machines and test this in a non-production environment without any major issues. I know microsoft recommends Basic and i dont know the long term drawbacks potential problems of doing this from an exchange server (if any) Has anyone actually done this and use exchange with dynamic disk in a production environment? Should i use another "PE" type software to expand the drive and leave it Basic or will it not matter at all? Just looking for any real world experiences that may help me decide what i want to do and i am fully able to test these without impacting prodution.
