Pool won't finish rebalance

[RobbieH]

Is there a way to find out why my pool won't finish rebalancing? I know I had this problem on another server where I had SQL Server running, but that problem was solved, and this one isn't running anything I can think of that would interfere with Drivepool. 

Version 2.2.0.906 if it matters, Windows 7...

Try installing this version, as it may help:

Also, try setting the balancing ratio 100%. 

[RobbieH]

It is still getting stuck at the same place. I would estimate it at about 60%.

I don't think it makes any difference, but so you understand my environment, I have two fast drives that act as my main drives, then a third drive that acts as the duplication drive. So, under Drive Use Limiter the two, fast 4TB drives are set up only for Unduplicated. Then, the 8TB shingled drive is set only for Duplicated.

That shingled drive is the one that went to RAW on me a while back, so I only want it to act as a backup drive.

Could you make sure that you're on the latest version (linked above), enable file system logging, and then rebalance?

After doing that, run the StableBit Troubleshooter on the system:

Sent. Thanks!

[RobbieH]

Chris, just checking to see if you got those logs. I did validate the version number and sent the troubleshooter files.

[Christopher (Drashna)]

If you sue the "rebalance" option in the UI (at the bottom), does that help?

 

Otherwise, all I'm seeing is "Cannot balance. Immediate re-balance throttled", which may be due to your balancing settings. 

[RobbieH]

No, it will move for a few seconds, then stop and say balance isn't optimal (or whatever that message is)

There are some additional changes, please download this version:

[RobbieH]

Just got to it today. I travel a lot for work sometimes, and this is one of those periods when I'm gone a lot.

It now says version 2.2.1.922. If I force a rebalance, it still doesn't get past 0.0% and stops.

[Christopher (Drashna)]

Could you enable tracing, and then force a rebalance?

And then run the StableBit Troubleshooter:

And what settings are you using for the balancer, or file placement rules. 

[RobbieH]

I have sent these files.

Regarding settings, here's what I said above. There's really nothing else to it than this.

I don't think it makes any difference, but so you understand my environment, I have two fast drives that act as my main drives, then a third, shingled drive that acts as the duplication drive. So, under Drive Use Limiter the two, fast 4TB drives are set up only for Unduplicated. Then, the 8TB shingled drive is set only for Duplicated.

[RobbieH]

Hey Chris, did you notice I sent those files last week?

[RobbieH]

Hey Chris, you can call this one "done". Yesterday the 8TB shingled drive started showing drive errors in Drive Scanner. I ran some normal stuff such as chkdsk /f and some other things and no errors were found. I don't know what happened last night but the drive went to RAW and I lost the partition. No biggie, it was the duplication drive, so I did not lose anything. This is the second time this has happened with this drive, and I don't know what's going on but SeaTools finds no errors. Anyway, case closed, bad drive. Since I pulled it, the balancing completed across the remaining drives.

[Christopher (Drashna)]

Oh no! I'm sorry to hear that.  But that could definitely cause this sort of behavior.
