Test driving DP. OFP and file placement rules expected behavior?


scutzi128

Question

Hi I'm test driving DP and I'm trying to use the OFP balancer along with file placement rules. Basically I want 2 specific folders to only be placed on specific drives that are faster then the drives in the rest of my pool and I want those drives to be balanced so that they obey the OFP rules. It seems like the drives with file placement rules are ignoring the OFP balancer. Is this expected behavior? Also the green bar at the bottom says file distribution not optimal but when I try to select re-balance it says balancing but comes back to the same message after some time.

I have a feeling that the balancing ratio is the issue here.  Try setting that to 100% instead of 1% (1% means it is very "lazy" about balancing, while 100% means that it's very aggressive) 

 

 

 

If that continues, please grab the Public Beta build, as there are a number of improvements to the measurement and balancing system that may fix this issue (and may make it easier to identify if it doesn't).

Unfortunately it seems that this behavior has continued with both the 100% setting and upgrading to the beta.

 

 

I had the exact same issue for the first time in several years of using DrivePool a couple of days ago.

Whatever I tried it always came back to "file distribution not optimal."

So is your machine on 24/7? If it is then try a reboot. Having planned to reinstall DrivePool to try and fix the issue on my days off from work, some other software gave me reason to reboot. Sure enough the balancing displayed as optimal straight after that.

Definitely worth a try. :)

I am using the latest beta btw.

What seems to be happening is any file moved to the folders with file placement rules it spreads the files across all the disks rather then filling up one then moving to the next. Is that working as designed? Also I noticed that when files are copied to the downloads folder for instance, the files are first saved to the the 4TB green drive then moved to the drives that have the folder placement rules. Thiis makes no sense to me. Why would it not just save to the correct drive to begin with and why save to the 4tb Green? Its down the list in the priories for the balancer.

Yes, basically.  

 

The Ordered File Placement balancer limits new file placement by using the "Real Time Placement Limiters" (the red arrows on each disk). Since you're ignoring these to force the file placement rules to place the files/folders on the "correct" disks that you want, it's reverting to the default file placement strategy, which is to place files on the disk with the most available free space.  And this sounds like it is exactly what you're seeing. 

 

Since I can't see the settings for it, are you using the "only affect new file placement" option, or for all files?

It is set to control new files and move existing files into predefined order. The other weird thing is that it always says that the file distribution is not optimal even after I manually tell it to re-balance. I find it odd also that new files added to the pool are being sent to the 4tb green drive, when it is not the next drive in the priority list.
