I've got a very specific task I'm trying to do, and I've got a number of different threads with things I've tried to get this to work, but none have so far.

 

Before I forget I'm currently running UnRAID v4.5.1.

 

Essentially what I'm trying to do is this:

 

I have an existing share over multiple drives. I have a database update I need to write to this share a couple of times a week. However, I need to write the database files to one specific drive in the share and I'm trying to find a way to "force" UnRAID to write ONLY to that drive (disk8). I've since discovered that's a very difficult thing to do - especially as the drive I wish to write to is the SMALLEST drive of the entire array.

 

Due to limitations in the database software (among MANY other limitations I've found) I MUST write to the media share , NOT specifically to drive/media share path.

 

The last way I thought of that might work is by (just prior to writing the update) going into the UnRAID web interface, opening the shares directory, going to the share and specifying ONLY disk8 in the included disks dialog. After applying that change, stopping and restarting the array the change does not seem to have made any difference. I also tried putting the other disks into the excluded list, but that didn't work either. I read and re-read the online UnRAID manual section on included and excluded drives and I can't find anything to explain why what I tried did not work so I'm asking the question here. Here's where I was reading....

Why, for an existing share, does altering the included (or excluded) disks not work? I might be wrong but, either I've found a bug, or a gap in the online documentation.

I'm not certain, since I've never used the included/excluded disk fields, but they may determine if a user-share-named directory will exist on a given disk.  If the directory already exists, it might use it for a file.

 

You might need to delete the empty directories it created on the other disks you do not want to write to.
