jtcweb Posted June 6, 2015 Share Posted June 6, 2015 I've tried reading up on docker, but the beginner guides I've found seam to start a step or two beyond where I am. On my webGui I don't have a docker tab like the instructions I find. I'm running version 6.0-rc4, upgraded from version 5. I read about the appdata share and there is talk about putting it on the cache drive, however I'm not running a cache drive as I do mostly reading as this is a media server. Plus I only have 5 physical places for drives in my server so I don't really have space for a cache drive. Do I have to have a cache drive to use docker? Is there a "Start from the very beginning" guide that I can read/follow? Is there somethign I have to do since I upgraded from v5? Thanks, Jerry Quote Link to comment
HellDiverUK Posted June 6, 2015 Share Posted June 6, 2015 I'm pretty sure you do need one. Why not pick up a cheap SSD? Even a little 32GB one would do the job. There's usually lots of used Intel SSDs on eBay that are more than suitable for a cache drive. Or you could use an old 250GB HDD? I've run an old 500GB WD Blue as a cache before and it worked just fine. Quote Link to comment
trurl Posted June 6, 2015 Share Posted June 6, 2015 Dockers and other apps write often to whatever disk you put them on. If you use a parity-protected disk for this, it will keep both that disk and parity disk active. This is the main reason most people use a cache drive for this, but it is not strictly required by unRAID to use cache for this. Quote Link to comment
jtcweb Posted June 6, 2015 Author Share Posted June 6, 2015 Could I use something like a 32 or 64GB flash drive as a cache drive? My biggest problem is I do not have space or SATA slots in my server for an additional drive. Quote Link to comment

My biggest problem is I do not have space or SATA slots in my server for an additional drive. The cache drive must be SATA. SSDs don't take much space, they don't really need a drive bay. If you don't have any SATA ports then that is a problem. Do you have any expansion slots to add ports? You could also move files around to free up a drive, maybe upsize a drive if necessary to make room (as long as parity is large enough). Quote Link to comment
