Problem with big File in Pool

Hi

I was using Drivepool (V.2.1.1.561) for aprx. 3 Month without any Problems. Last Week I copied a big File (800GB in one File) to my Drivepool, and Drivepool is not able to balance the Pool.

My Drivepool use 2 Disks (1T each named CACHE A and CACHE as cache, and 2 Disks (8T each named “ARCHIV A 1” and “ARCHIVE B 1”).  I use only the “SSD Optmizer” as Balancer.

I am able to copy the big file to the pool without any problem. I can see the file on the 2 CACHE Disks. After finishing the copy, the pool start to balance.  (I can see the activity Led’s on the 2 Disks (one ARCHIV & one CACHE)) The Progress continues to something about 2% then restarts without any error again with 0.2% and so on. If the Process starts again the Target Drive is changing (I can see this on the Activity Led of the Drive.)

In the Log File I can find a Warning like:

DrivePool.Service.exe  Warning              0             [FileMover] Error moving '\\?\Volume{9bd3e1c2-cfee-4611-8d32-3d37ba293688}\PoolPart.aaa84030-e4de-4a84-ac23-09c7c2711284\Archiv\Backup Veeam\PAP Alle Produktiven VM2016-04-10T143651.vbk' to '\\?\Volume{514e8456-d9c0-4fe7-870d-b082b2fc97b5}\PoolPart.838af591-1ccb-410d-9658-06ec3463365d\Archiv\Backup Veeam\PAP Alle Produktiven VM2016-04-10T143651.vbk'. Falscher Parameter                2016-04-10 17:37:17Z     45157247662

If I delete the big file, select “Neu erfassen…” in the Pool Options, my cache drives are empty, and the pool seems to be ok.

The Service Folder as zip file is attached.

Thanks for Help

Best Regards from Austria
