Pooled Drive becomes unusable and Drivepool can't balance or duplicate files any longer


notrix

Question

Hey,

I added a new drive last week and for the last couple of days I notice strange issues.

First, there are times when I'm not longer able to write to or read files from the Pooldrive. Only option is to restart the server. But after some time the issue rises again.

Second, Drivepol is not able to balance or duplicate files in the pool any longer, everytime it tries to do so or when I force the rebalance, there are just errors noting: "Cannot balance. Immediate re-balance throttled."

Also, when the Pool becomes unresponsive, i see a lot of "[FileMover] Error moving '\\?\Volume........................."  -> System Cannot Find File Specified. (I hope that I translated that right, since it's German for me). Additional I can see a lot of "[DuplicationTagsConsistency] Error clearing destination read-only attribute from " and "[DuplicationTagsConsistency] Error copying alt. stream from".

The strange thing is that these errors happen on different drives, so I don't think it's a harware issue. Also Stablebit Scanner says everything is OK with the drives

Hope someone can point me in the right direction.

And if it is important: I'm on Server 2019 with no updates installed the last 3 weeks, so I can exclude that as an issue.

I also installed the newest (stable( Version of Drivepool just to make sure.
