May 3, 200818 yr I just built my new unRaid Server, running ver. 4.3.beta6. I'm still a little confused as to how the user shares/split level works. I have 3 - 1TB hard drives (2 data, 1 parity) installed and configured. Given the following example of how I'd like to set up my directory structures, what would be the proper User Share/split level configuration needed? Disk1 | Videos (User Share) THIS WILL SPAN DISKS | --Movies (Directory) | --DVDs (Directory) | --[Movie Title 1] (Directory) | | | VIDEO_TS (Directory) | .VOB file | .VOB file | --[Movie Title 2] (Directory) | --VIDEO_TS (Directory) .VOB file .VOB file Disk2 | --Music (User Share) WILL NOT SPAN DISKS | --[Artist] (Directory) | --[Album 1] (Directory) | | | .mp3 file | .mp3 file | --[Album 2] (Directory) .mp3 file .mp3 file The Videos share would need to span multiple drives as my DVD collection grows. It's okay for the Videos, Movies, DVDs directories to be split across drives, but obviously I would need the Title directory to not be split (thus keeping each title and its corresponding .VOB files intact). I currently have allocated the following for this, and have begun copy of Movie Titles directly to the DVDs subfolder: Share Name: Videos Comments: Allocation method: High-Water Split level: 3 Included disks: disk1,disk2 Excluded disks: Export mode: Export read/write If this is correct, I could do the same thing with the Music share, setting split level to 2? I want to be sure the split level is correct. Also, am I correct in assuming that a new Videos directory will not be created on disk 2 until the high-water mark is reached? Thanks for all the expert help in forums and wiki so far!
May 3, 200818 yr To answer your question I added the level number to the left: 0 Disk1 | 1 Videos (User Share) THIS WILL SPAN DISKS | 2 --Movies (Directory) | 3 --DVDs (Directory) | 4 --[Movie Title 1] (Directory) | | | VIDEO_TS (Directory) | .VOB file | .VOB file | 4 --[Movie Title 2] (Directory) | --VIDEO_TS (Directory) .VOB file .VOB file You want split level set to 3 so that any object created in either the Vidoes, Movies, or DVD directories will be allocated to a disk according to current allocation method. Hence, when you create a movie title directory, say, "Aliens", since this is being created in a parent directory at level 3, the system will choose which disk to create the "Aliens" directory according to allocation method. But when you create any object within the Aliens directory (or below), that object will be created on the disk that the Aliens directory happens to be on. For your Music share, since you don't want it to span multiple disks, you set up the share config as follows: Share Name: Music Comments: Allocation method: High-Water [doesn't matter] Split level: 0 [actually doesn't matter what you set here] Included disks: [set this to the disk you want the Music share to be on] Excluded disks: Export mode: Export read/write Also, am I correct in assuming that a new Videos directory will not be created on disk 2 until the high-water mark is reached? Correct!
May 4, 200818 yr Author Thanks for the visual clarification. It helps me to understand split level much better.
July 18, 200817 yr I have a similar question to Rob's inquiry. I just installed unRAID a couple of days ago and was wondering what the best split level for me was. Here's my config: 3x 1TB drives, 1 parity, 2 hds in the array: Disk 1 | Media | Movies | -Directory1 -Directory2 -Directory3 -File A -File B -File C -File Z I created a user share named 'Media' and chose High-Water and split level 2. I then started copying about 500GB of files over to it. Today, I noticed that all 500GB saved to disk1. Can someone tell me if that's the correct behavior with the High-Water / Split Level 2 combination? I was expecting for Directory2 and Directory3 to go across both disks as well as some Files A through Z. Thanks!
July 18, 200817 yr Can someone tell me if that's the correct behavior with the High-Water / Split Level 2 combination? I was expecting for Directory2 and Directory3 to go across both disks as well as some Files A through Z. Thanks! The idea behind high water is that it will fill up disk 1 to 50% then move on to disk 2 and fill it up to 50%. So, since you have 1TB data disks it should write 500GB to one disk before moving on to the next disk. Once both disks have reached the "high water mark", it will repeat the process going through the disks filling up 50% of the available space. So, the second time around it will fill each disk to the 750GB mark before moving on. That is my understanding of how it works.
July 18, 200817 yr I realized I didn't address the split level portion of your question. When disk1 reaches its high water mark then new files and directories in your Media folder will be created on disk2. However, files you copy into your existing disk 1 directories inside Media should still be written to disk 1 because you have split level 2 set.
March 20, 200917 yr I had questions and meant to respond here but ended up making a new topic here: http://lime-technology.com/forum/index.php?topic=3509.0 Sorry. Hopefully you guys can answer my questions, thanks.
