Array Usage of Disks

[toolmanz]

I have an unraid instance running on a Dell R710 server. It has 5 disks of various sizes plus the 8Tb parity disk.

 

I recently started getting a warning on the size of one of the disks that it was around 75% full.

 

The main screen bears that out. 

 

That's ok - but I have a disk with 4Tb that hasn't even been touched - it remains empty.

 

Does this represent a problem? 

 

Are there settings that distribute disk space evenly over my 5 disks? 

 

Kinda lost here.

 

Is there a direction I should look into to find out what the problem is.

 

Any help is appreciated.

 

Thanks

How files are distributed depends on the settings you have set for your User Shares.

 

you should post your system’s diagnostics zip file (obtained via Tools -> Diagnostics) so we can see how you have things set up if you want any sort of informed feedback.

Thanks.

 

I should know to do this - I've done it before. Doh! 😵

 

Ok I will upload the zip file. Attached

 

Thanks

I didn't want to wade through all 47 of the share .cfg files in those diagnostics. Do you really have that many user shares? Probably not but unfortunately no way to know from diagnostics, without opening each of them, which actually correspond to existing user shares and which were created (perhaps accidentally) at some time in the past but are no longer used.

 

In any case, what you have seems like the expected Highwater allocation. When that disk gets past 75% I would expect it to reevaluate and choose disk7 (or maybe disk8) for a while.

Disk2 was 72% in those diagnostics so maybe you moved some files off it yourself.

This is a pick of the shares currently. As expected.

 

 

 

I checked out the contents of each one and they are as expected with the shares that are below.

 

 

So no issues to be concerned with?

Oh forgot to add the highwater mark is 70% on disk 2.

 

Does that trigger changes in unraid that cause the system to change where the files are stored?

I think you must be referring to threshold, not highwater. There is no way for you to set Highwater.
