StableBit DrivePool DrivePool 2.2.0.701 Beta running on Windows 2012 R2 Standard with 2 Pools.
One pool containing 4 harddisk partitions (on 4 separate harddisks) which works perfectly.
One pool containing 2 SSD partitions (on 2 seperate SSDs) with (VDI) deduplication enabled, Bypass fill system drivers is disabled.
Pool is configured to mirror one specific directory containing VHDx files which deduplicates quiet nicely:
FreeSpace SavedSpace OptimizedFiles InPolicyFiles Volume
--------- ---------- -------------- ------------- ------
190.59 GB 166.58 GB 9 9 E:
120.26 GB 166.38 GB 9 9 F:
Since the moment that {SavedSpace of E: and F:} > {FreeSpace of E: and F:} DrivePool no longer shows Statistics. It says 'Statistics are incomplete' and I am never able to rebalance anything because of this.

Both Read Striping and duplication is working so it seems it is just a cosmetical error.
I actually think I understand what is happening here, probably DrivePool does not expect there to be more data on the drive than can physically fit.
Is there any way to fix this issue?
