Hi Team, Im getting a notification that one of the disks is at 71% use, Im not sure why the data is not balanced or managed across all the drives.  Should I do something to make sure its not an issue?

How storage is used is determined by a combination of a number of share settings such as allocation method, split level, minimum free space, included/excluded disks, etc.

 

You should read up on these settings from User Shares section of the linked manual in the bottom right of the GUI.

 

Mine is setup :

 

Since you have quite small disks, i'd change that Minimum free space to something like 10GB; or your disks are going to stop allocating data with 58GB free on them. 

 

As to the allocation; you're using High-water so it will try to fill up the disk to 50% then move to the next and do the same...then cycle back through them again. 

It does this progressively though; so if youre copying a large directory to the array it will allocate it all to the disk its currently targeted with High-water. 

 

You can read more about it in the docs here: https://docs.unraid.net/unraid-os/manual/shares/user-shares/#high-water-method

 

Do you have other shares as well on these disks?

The allocation is a per share setting; if you have other shares that are using Primary Storage "Array" then they will also affect how full the disks get in total

 

Edit: If you want them to be as equal as possible; then change it from High-water to Most-free

With high-water allocation then the relative size of disks can become relevant as the high-water cutover points are based on the largest drive but your screenshot does not show the sizes so we cannot see if the behaviour is what should be expected.
