December 8, 201510 yr I'm probably doing something stupid... I have 4 drives, 1 parity, and 3 data discs. In the Shares tab, for example, the "Music" share is setup as following: Allocation method: Fill-up Split level: Automatically split any directory as required Included Disks: All Excluded Disks: None Enable COW: Auto I'm copying from my Linux machine where the unRAID share is mounted as NFS to /mnt/user/Music. The first drive is almost full, and copying stops soon as it is completely filled up. As far as I can tell, unRAID mounts specific disks under /mnt/disk[x], and the "pooled" view is mounted under /mnt/user/Music. I temporarily disabled parity, just to see if it would make a difference or speed things up -- but no difference in terms of splitting data. I read the wiki, I can't figure what I'm doing wrong here. I have the 12 drive license, not that it would or should matter since the data is simply on the first drive and not going anywhere else... Help!
December 8, 201510 yr Community Expert What have you set as the Minimum Free Space level? You should set it to be at least the size of the largest file you will copy. This will stop unRAID selecting a disk that does not have space for the file.
December 8, 201510 yr Community Expert Since v5 never heard of COW ... Enable COW: Auto ... moving this to v6 support.
December 8, 201510 yr This is because of your allocation setting: Fill Up. Read: http://lime-technology.com/wiki/index.php/Un-Official_UnRAID_Manual#Allocation_method
December 8, 201510 yr This is because of your allocation setting: Fill Up. Partially true. It's not actually because of the "fill up" setting -- it's because you don't have a minimum free space setting (as Itimpi noted). UnRAID NEVER splits a file across drives (as your title implies you expected) => it selects the disk to write a file to based on your allocation method; but once selected if it runs out of space it will fail. With "high water" or "most free" allocation methods, this isn't likely to cause an issue, since the disk selected will generally have plenty of space; but with "fill up" you need to be sure you set a "minimum free space" value that's as large as the largest file you'll be copying to the array. Then UnRAID will select a different disk if there isn't enough space on the disk for your copy.
December 9, 201510 yr Author Thanks for the clarification. I'm above to copy now, I just selected highwater.
