August 4, 20232 yr Is this normal to have a share set to high water mark and files never being written to it. As you can see Disk 5 is not touched. Share Settings. I would expect all disks growing evenly. Any thoughts on what the array is doing.
August 4, 20232 yr Community Expert Looks to me like it is working correctly ? Are you sure you know how high-water works? It is described here in the online documentation accessible via the ‘Manual’ link at the bottom of the GUI or the DOCS link at the top of each forum page. Quote https://docs.unraid.net/unraid-os/manual/shares#high-water the high water mark is based on the largest drive (13.8 GB). That drive will therefore be used until next high water point of 6.9GB is used) and then disks are used in turn until they drop below that. Next high water mark is 3.45 GB and disks are used in turn until that point reached. At the moment that phase has only got as far as disk4.

Parity array disks are not pooled at a bit level, each one can have different filesystems if desired, and are independent from each other, and can be read separately if needed.
August 10, 20232 yr Author Thanks for the information. I changed the share to most-free and now all my zfs disks are growing evenly.
