April 9, 201115 yr Hey all, Something has been bugging me, has been happening since I started using unRaid but only now have I got the time to do something about it. When watching a movie or listening to music, and a drive spins up, then the stream will pause while it waits for this to happen. Is it a caching issue on unRAID's side of things? Doesn't really matter which program is in use, it will always happen. Happens in both SMB and AFP, so appears to be separate from sharing protocol. If I have something shared off my other Hackintosh with AFP, and I spin up another drive there's no issue. Ideas? Cheers!
April 9, 201115 yr While weird that it doesn't affect your other systems, this is totally normal with unRaid. If reading off disk1 and suddenly it needs to read from disk2, the feed does have to pause while disk2 spins up. Just the way it is. There is no "caching" on reads from unRaid itself. I would says adjust your Split Levels so files within a a folder like this are not spread among multiple disks. Or, create a Spin Up group - so all the disks associated spin up at the same time, this would also alleviate this issue. Shawn
April 10, 201115 yr Is the drive that's spinning up also containing the data being streamed? If so, then the split-level settings are there to allow the data to be placed all on one disc as needed to prevent that problem. If the drive is spinning up because it contains some other data that is needed, perhaps by another user, and if that is then interrupting the streaming, that would suggest a lower level problem within unRAID or its settings. Certainly with my server I can cause a drive to spin up (for audio streaming) while I am serving video to XBMC somewhere else and the video streaming is not held up during the spinup time of the audio drive. I would therefore think that it is the split-level settings that you need to look at. Of course, if you make changes then data already on the server will not be moved - you'd need to manage that separately.
April 10, 201115 yr Author Usually just affects music stream. Have all my music on one drive, and movies / tv shows on the others. If, for example, plex media server starts a library update then it will spin up the other drives and there will be a delay in the music stream until they have spun up. This is happening on the same computer, with the same user. Don't have additional machines that connect to unRAID usually.
