DPM Storage Pool disk utilization

  Hi Everyone,

   

  I currently have a client who is running DPM 2010 on Server 2008 R2 SP1, they have a storage pool configured with 5 disks

   

  Disk Total Capacity % Unallocated

  Disk 1  8TB 7%

  Disk 2 2TB 12%

  Disk 3 2TB 51%

  Disk 4 2TB 3%

  Disk 5 3TB 6%

   

  Disk 4 is causing backups to fail as there isn't enough space for new backups. I need a way to move some of the backups from Disk 4 to Disk 3, I've had a look at the powershell script MigrateDatasourceDataFromDPM however I don't have enough space to relocate an entire disk of replicas to another disk, I only want to move a small portion of data sources on one disk to another.

  They currently have just one Protection Group that has 106 members so I can't migrate the data based on the Protection Group

  I've had a look at a few powershells commands and the one that seems most relevant in Get-Datasource what I'm hoping to do is filter that to only list the datasources on Disk 4 and then from that, filter it again so that I can move a few of the items from Disk 4 to Disk 3

  If someone can please point me in the right direction I would really appreciate it as the client is starting to miss backups.

  As a side note I found a script to shrink the dynamic disks using DiskPart which I've run and recovered some space on several datastores however that isn't a long term fix, the short term protection is set for 5 days then it is written to tape so I can't shorten the retention period either.
