Hi all,

 

Still a newbie and sorry for any confusion, or repeated queries that others might have before me.

 

Tower diagnostics attached*

 

My setting for the share is:

Allocation method: High-water

Split level: Automatically split any directory as required

Minimum free space: 48.8 GB

 

 

My files are still all stored on disk 1 (750 GB/ 1TB used) and disk 2 (693 GB/ 1TB used)

and rest of my disk 3,4,5 (500 GB each) are not utilized.

 

My understanding of high-water is that when disk reached half way (disk 1 at 500 GB), it'll then store the files into disk 2, until 500 GB is reached.

Then, it'll move on to store files at disk 3. 

 

Is my understand inaccurate?

 

Thank you once again for your help! Welcome any feedback for other improvements too (I mainly use this for storage and will setup container to run apps in the future).

Since the other disks are smaller, it will only write to them once disks 1 and 2 are over 75% used:

The cutover point is not a percentage of the disk but based on the actual size of the largest data disk.    The largest disk is 1TB so the first cutover  point would therefore be 500GB and at point the remaining disks are not larger than this so are not used.  The next cutover point will be 250GB so disk1 and disk2 will be used until they get down to this, and then disk3 will start being used.

Thank you both for your help! I really appreciate it and now I fully understand how High-water allocation works.
