Windows Mount Points and Host Volume Free Space

Posted on 2011-10-04

Hi, planning to use mount points for Exchange 2010.  Question: What happens if the drive where the mount point resides fills up? For example, let's say I have a D: drive and within the drive I have D:\MountPoint.  If D: ran out of space, would D:\Mountpoint still be accessible?  Thanks.

    Yes, the mountpoints do operate seperatly.
    The best thing you do is create a small D-drive (few 100 mb's) as a 'root' disk and have mountpoints mapped on this disk 1 for a mailbox db and 1 for the logdisk.
    Note that if you have a slow 'root' disk, the mountpoint will suffer from the low performance of the root disk, but for diskspace reporting, this shouldn't be a problem.
