Shouldn't Unraid load-balance the data between drives?

[JP]

I just received a utilization warning for Drive 1 from Unraid.  I don't think I've ever had one before.  I took a look and as you can see below, something doesn't feel right.  All data seems to be loading up on Drive 1 and I can't figure out why.  I've had Unraid I think running for over a decade and I'm sort of stickler for leaving everything at default.  Basically, I'm not going into Unraid and asking it to put specific data on a specific drive or anything like that.  I've always let Unraid decide that for me.  Is this normal, and if not, is there something I should do to resolve it?

The default is high-water, if a share is set to say split between disk1 and disk2 it'll start writing on disk2 once free space on disk1 is less than half the free space of disk2.

So looking at that screenshot if it was the case above it'd start writing on disk2 pretty soon, seems normal.

You can read about the different allocation methods here:

So if I'm reading this correctly, my Disk 2 has 2 TB of free space.  Half that is 1 TB.  Once Disk 1 reaches 1 TB of free space it will start to fall over to Disk 2.  Is that accurate?

 

If that is accurate, then I guess this is all normal, which is awesome news.

Yep, assuming high-water is selected.

Thank you!  Yes, High-Water is selected for all my shares.

Thanks for this.  I guess I need to bite the bullet and find a way to get away from REISERFS.  These instructions should help me.  Thanks again.
