I've created a backup UnRAID server. I has two data disks (parity will come later, after copy done).
I've noticed a difference in behaviour about where files go depending if I'm copying the files from Windows or Linux (specifically, another UnRAID server). All computers are on the local network. The destination server has a Media share set to Split first two levels (within the share I have Movies and TV Shows directories, then under that a folder holding each movie or TV series). Method is Fill Up, 10G minimum space, but the same behaviour is seen regardless if this is High Water. Included disks All, Excluded None, use cache disk No, Security Public, Enhanced OS X No.
What I'm seeing is that when copying via rsync from the other UnRAID machine, only disk 1 is used, and the copy continues until there is no space left, ignoring both the allocation method and minimum free space settings. When copying the same files from Windows, the copy spills over to use disk 2 when the minimum space is hit and the copy continues as expected. Even if allocation method is high-water, rsync will totally fill disk 1 and error out about no space left, when disk 2 is sitting there unused. I copy some files from Windows to the same share and now I see files going to disk 2.
rsync is writing to /mnt/user/Media, the same share I'm writing to when I using WIndows (via SMB to Media share). I notice there is also a /mnt/user0/Media - maybe I should be using that directory instead of /mnt/user/Media?
Anyone else notice this behaviour?
