Ice_Black Posted January 13, 2016 Share Posted January 13, 2016 A feature of Real-time cache to array support would be awesome, in other word - real time mover. Basically in the share setting, we enable cache "Use cache disk" to Yes and have another field called "Real-time Mover". If "Real-time Mover" set to Yes: 1. Copy a file to array Share 2. It get stored on the cache disk 3. unRAID somehow detect if a file is successfully copied and then instantly move to Array. Quote Link to comment
John_M Posted January 15, 2016 Share Posted January 15, 2016 I'm not sure I see what the advantage would be compared with simply not having a cache at all! Now, if you were to suggest an intelligent mover - one that ran whenever the cache is more than x% full (where x is a user setting) and/or when it detects that the sever is idle and/or the relevant disks are spun up - you'd get my vote. Edit: Apologies, I didn't really think it through before replying. I suppose a real time mover would still speed up write access to the server. Like having a write cache on a hard disk. Yes, I support that idea. Quote Link to comment

limetech Posted October 31, 2016 Share Posted October 31, 2016 Yeah it's a good idea. It's been on my "todo" list for ages. I call it "continuous move". Quote Link to comment
bonienl Posted November 1, 2016 Share Posted November 1, 2016 Perhaps I can help out. I created a "Continuous" mover setting (see attachment). The principle is based on "inotifywait" which monitors the cache drive for newly added files, and checks if files need to be moved to the array as soon as they are completely received on the cache disk. I have a working solution, but it is beta state. E.g. no full checking is done yet, script expects cache device to be present. Also setting won't survive a system reboot. If any interest I can make it available as a test plugin. Quote Link to comment
Guzzi Posted November 3, 2016 Share Posted November 3, 2016 Nice one - would drastically reduce the time data on cache drive is unprotected (if cache is not mirrored) :-) Quote Link to comment
