I have a few questions on how a cache drive will function in the following situations:

 

Specs: My cache drive is 80gb and my data drive is 1tb (only one, so the files won't be spread across multiple disks).

 

1)  I have a bunch of data that has already been written to the main drive.  It's roughly 200gb worth of files, about 1mb per file.  I want to move all of these files from one folder to another, within the same user share (from \share\unprocessed to \share\[year] to be precise).  Will this cause the cache drive to be used, or will it all happen in place on the main drive?

 

2)  I have a bunch of files that are already written to the main drive and I have newer copies of each file (on my main PC, not on the unraid) that will be replacing them.  This will write the files to the cache, and if they are accessed before the transfer from the cache to the main disk then the newer files are the ones that will be accessed from the user share, correct?

 

Thanks for any info on this!

First of all, are you using a parity drive?  If not, then there is no reason to use a cache drive, as there will be no benefit from it.  You will be better off using that 80 GB drive as a data drive, or not using it at all.

 

If you are using a parity drive in addition to your 1 TB data drive and your 80 GB cache drive:

 

1) Yes, the cache drive will be involved in this transfer.  You should go into your settings page and manually disable it until all your large transfers are complete.

 

The other way around this is to do the move via the command line, but I don't know enough about that to guide you.  A hero member can help.

 

2) Correct.  If you are overwriting files on your server with newer versions of the files, then the overwrite will happen immediately, whether or not you are using a cache drive.  As soon as you have finished transferring the new files, the old ones will be inaccessible. 

Yes, I'm using a parity drive, forgot to mention that (it's a duplicate of the 1tb drive).

 

Thanks for the info!
