highwater not working?

[RTOuk]

hi, i have my new unraid box set up now and have been copying my data across from my drives which i shall then add to the server once they have been copied. the problem is i have one share set up that i point my media centre and windows pcs to. which is set up as highwater, the split level is left blank as i dont care about where things end up. but it doesnt seem to be working, the biggest drive just keeps getting used.

 

as you can see in the attached screenie the 1tb drive has been used to to point of only having 300+gb left. shouldnt it have moved onto another drive by now? im wonder if it might be bacause i have left a gap as the drive im goint to install into the second postion is the one im currently moving data from (im trying to keep them in size order so i can find the smallest easily when i upgrade)

 

other than that everything is running great

 

any suggestions?

update:

 

the server has now started using the 500gb drive when the 1tb drive hit 243gb (about 1/4of the size). it was my understanding that the highwater was set at 50% of the largest drive? it seems to have been set at 25% in this case. has the highwater mark level been changed? im curently using the 4.5.3

 

thanks

The split is between disk1 and disk3. I believe unRAID will fill the drive with the most empty space until 1/2 of the free space on the next drive in line is more than the remaining space free on the drive in use.

 

In other words, disk1 had the most space so it filled disk1 until the remaining space on disk1 was less than 1/2 of the empty space on disk3. Next it might only fill disk3 to about 75gig before it begins to fill disk5.
