RGauld Posted March 29, 2017 Share Posted March 29, 2017 I have unRAID Server Plus v6.3.2 and I'm trying to setup my TV Series share... I have about 8TB (361 Folders, 15,085 Files) to copy to my 12TB array... I have setup the share to use the High-water allocation method, with a Minimum free space setting of 30GB (as my largest file is about 14GB), and the Split level is set to Automatically split only the top three directory levels as required. My question is, If I copy all of these files at once (using Windows 8.1 SMB copy to my mapped network TV Series Share), how can I insure that the files are spread evenly across my 9 hard drives? Do I have to copy them in chunks, or can I simply copy them all at once? I want to ensure there is at least 15% free space on each hard drive. Link to comment
RGauld Posted March 31, 2017 Author Share Posted March 31, 2017 can anyone help me with this? Link to comment
digitalfixer Posted March 31, 2017 Share Posted March 31, 2017 If your files and folders are in ShowName/Season X/filename.ext then I would only split the top two levels. This keeps a whole season together on one disk. Kevin. Link to comment
RGauld Posted March 31, 2017 Author Share Posted March 31, 2017 Yes, but the folder structure is as follows: Media2\TV Series 2\ShowName\Season XX\filename.ext As they are 3 levels down, I was under the impression that I had to split the top 3 levels... Link to comment
JorgeB Posted March 31, 2017 Share Posted March 31, 2017 Split level 3 is correct for your folder structure. Link to comment
tdallen Posted March 31, 2017 Share Posted March 31, 2017 Two points. First, unRAID won't fill drives evenly as the copy is underway with high watermark - that will be the end result, but with high watermark it will fill one drive to the high watermark, then the next, etc. If you want to see it fill drives evenly then you'd use most free, but that spreads your files all over the place. High watermark is preferred. Second, if you really want to guarantee 15% free space then you'll need to adjust the minimum free space. The traditional role of minimum free space is the biggest single file size you intend to copy to the share. But that's eventually going to fill the drive up to 99.9%. Is there a reason you want to keep 15% free? That's pretty generous. Link to comment
RGauld Posted March 31, 2017 Author Share Posted March 31, 2017 I found that filling a hard drive to more than 85-90% capacity tends to slow the drive down... Also, most hard drive manufacturers recommend not filling your hard drive to 99.9%... I'm just trying to distribute the 8TB of data evenly across all 9 hard drives.... Is there no way to do this?

Most free on the allocation method. (Split level on the shares will take precedence over it though) Link to comment

RGauld Posted April 1, 2017 Author Share Posted April 1, 2017 All seems rather confusing.... I guess I'm going to stick with the "High-water" allocation method... Link to comment
