Fragmented MBS storage RRS feed

  • Question

  • Hi I have problem with MBS on latest DPM 1807, MBS REFS volume got 100% fragmented, but when I try to defragment volume it stall in 100% analyzed and nothing is happening, then optimize disk process is consuming about 30 % of cpu time and 5GB memory, and nothing happening it about 24 hours, volume has 5 TB and is half full. What should I do to defragment volume.

    Thanks osozu

  • Hello Osozu,

    You could try to manually optimize / defrag the volume, below are two ways of doing it:

    Method 1 - PowerShell

    1. Open a PowerShell.

    2. Write and execute the following command:

    Optimize-Volume -DriveLetter E -Defrag -Verbose

    Method 2 - GUI

    1. Open a File Explorer.

    2. Right Click on the volume and choose Properties.

    3. Go to the Tools tab.

    4. Click on Optimize.

    5. Select your drive and then click on Optimize.

    See whether any of these methods works out for you!

    Best regards,

  • Hi Leon i have already try gui and cmd but it always hangs at message 100% analyzed and nothing happened, defragmentation doesn't start, its still wants to analyze volume even if i run only optimization

  • It does this by design by analyzing the disk first, did you try with the PowerShell method to see if there's any difference?

  • Make sure the console isn't just "stuck", press any key to see whether it has finished or not.

    I do believe larger volumes, especially ReFS might take longer to analyze/optimize but it shouldn't still take too long.
