Hi Guys,

 

If I want specific files to be on the cache drive for best performance (for example video files for use in a video editing project), how do I temporarily move just those required files to the SSD cache drive? At the moment all those files are on user shares that are set to Cache > Array.

 

As far as I understand, I can set the share that those files reside in to be set from Cache > Array to Array > Cache (and then run the mover?), but what I don't understand is, that share may have XX TB of data on it, whereas my SSD drive is only 500GB. When set from Array > Cache does it just load the individual files into the cache drive when I access the individual files on the array, like adding them to the media bin in my project? 

 

If I have 1TB of video files that I may or may not end up using in my project, does that mean I'd need a 1TB cache drive to be able to load them all into cache to enable the best performance when doing the editing? 

With my current 500GB SSD, I assume I'd have to load half of them, work with those first and then move those files back to the array to empty the cache drive, to load the second half?

 

Thanks

There is no setting that will do exactly what you want.

 

A workaround would be to have a special share that is set to only be on the a pool, and then put the files in that share when you want to work on them, and then when you are finished put them back into a share that is set to finish on the array.

 

Another possibility is to simply not have such files on the main Unraid array at all, and have a redundant pool (probably ZFS format as that will give good performance) to hold the relevant share(s)

Generally these files wont be accessed regularly except for when I am working on the project that demands them. So would you say the first suggestion of moving files into a share that only uses the pool is the best option here?

 

I'm assuming most people would want performance when using certain files on their server, is that what most people would do? transfer them to a share that resides in cache only?

I am not sure that there is a 'most peoples' solution at all as people's work patterns can vary so much.
