I have set Split Level 0 meaning i have to manually set the folder structure on the various disks. and have set high-water as the allocation method along with min-free space as 10mb (for testing on 3x 250MB Virtual HDD's)

 

I have setup UNRAID in a VM to test the allocation method as started above, Before playing with my real server

 

I have one issue.

 

I have both;

disk1\media\tv shows\ (disk is 250MB)

disk2\media\tv shows\ (disk is 250MB)

 

with a usershare of \\tower\media\tv shows\ (disk is 500MB Combined Space)

 

now if I create a folder in the usershare for "Lost" and then a "Season 01" folder, then copy 3 dummy files (50mb files) Lost.S01E01.DMG etc. to the share and they copy to the created folder and end up on disk1 which is fine. now what happens when disk1 is full (i have min-free space as 10mb for testing) i expected it to go, right i will have to break split level to continue adding files and then create another "Lost" folder on disk2 and copy the other files to it.

 

 

 

At the moment it seems high-water works if i have two different shows (lost and Prison Break, for instance) but the show is confined to the initial drive that the "Lost" folder is created. This actually works ok for me, I just need to move the show to another drive later if I run out of free space on a drive.

 

This post is more of a sanity check. So any info on the above and insight would be greatly appreciated!

 

cheers.

The high water allocation method will fill 1/2 of the disk that has the most free space first...

 

so it will fill disk1 until there is only 75mb left on the disk, then it will move to disk2, and fill that until there is 75mb left on that disk.

 

Next it will go back to disk1, and since there is 75mb free, it will fill half of that again.  So it will write until there is 37.5mb free, and once again move back to disk2....

 

so on and so forth...

 

is this what you are asking or looking for in an answer?

thanks mate, that cleared up high-water which I was 99% sure on. it is more the fact of what happens when there is no freespace on disk1 (say it has just filled drive1 to 75% and only has 75MB free, then i go to copy an 80mb fileto the usershare. knowing that disk2 has 150MB freespace and due to high-water it should start filling disk2 to 75% etc. But during testing i just get a "no freespace error" in OS X. is this because high-water wont use disk2 for a TV Show if the show folder already exsists on Disk1 eg;

 

 

RED = Split Level 0 (manually set by me), Green = Controlled by High-Water

 

 

Disk1\Media\TV Shows\Lost

 

Should it, after Disk one filling up, create the show folder on disk 2 as well like so

 

Disk2\Media\TV Shows\Lost

 

 

thanks for your help so far

Alright, I'm not an expert...

 

But, did you change your split level allocation?  Cuz you said in the 1st post that it was at 0.  I think with it being at 0 YOU have to put the drives in the SPECIFIC disk.  I don't think it will change disks for you, but someone correct me if I'm wrong. 

 

As for the above...split level 2 would Keep each TV show directory within the same disk...I think that's what you want...

sorry, I still have Split Level 0, let me correct my post above to better describe my setup but my worry is what happens if i fill both drives and then add a third. will the TV Show folder eg, "Lost" be automatically created on disk3 as disk 1 and 2 are full?

Ok I'm not sure with a manual split-level if it will overflow onto a full disk...

 

TTT for you for an answer...

No. Split level zero means that you manually must create all directories. If you create the directories on the empty disk then the allocation method will choose it.

So.... if i wanted Lost to spill over to Disk3 i would need not only the top level folders /Media/Tv Shows/ but also the "Lost" folder. would it then split "Lost" over to disk3 as new episodes were to be added?

 

i think im finally beginning to understand this
