tucansam Posted December 6, 2022 Share Posted December 6, 2022 I've finally upgraded my server after 10+ years. My final task is to copy the contents of an old Evo 850 SSD to two new m.2 SSDs. Is it worth placing docker.img and appdata on different SSDs, for the sake of performance? Thanks. Quote Link to comment
JonathanM Posted December 6, 2022 Share Posted December 6, 2022 Maybe? I have my docker.img on the same drive with my staging and unpacking downloads, and appdata on a different one. My reasoning wasn't so much performance as tiered risk, I don't need to bother backing up downloads in progress or the docker.img, but the appdata gets backed up daily. Quote Link to comment
tucansam Posted December 6, 2022 Author Share Posted December 6, 2022 You're backing up appdata daily? How many docker applications are you running? My appdata directory is 102GB, and the Plex instance alone is several million files. I'm backing it up weekly. Five or six dockers running, the usual suspects I suppose. And docker.img is not super critical? Where is the config data for each (sab, plex, etc) stored -- appdata or in the docker.img file? Quote Link to comment

Unless some dockers are not properly configered and write their config data in the image. Quote Link to comment

Just select apps that I would be ticked if I lost a whole weeks worth of changes. I have CA Backup doing a weekly, and I script daily backups for the critical stuff. Also, I don't plex, so my ENTIRE appdata backup archive is less than 40GB. Quote Link to comment

tucansam Posted December 6, 2022 Author Share Posted December 6, 2022 Unfortunately docker won't let me set the appdata path. I'm in the docker tab in the web gui. I was able to set the path to "/mnt/disks/ssd1/docker.img" for the docker file, but its giving me a "path doesn't exist" error for "/mnt/disks/ssd2/appdata." When I browse from that form field, it only shows me directories in /mnt/user -- it will only look to the array for an appdata path. Is it possible to store the appdata on an ssd mounted with unassigned devices, not in the user shares? Quote Link to comment

With the advent of multiple pools, why would you want to use unassigned devices for a critical part of unraid? UD's primary purpose is transitory media, not permanent storage. Quote Link to comment
tucansam Posted December 6, 2022 Author Share Posted December 6, 2022 I don't know any other way. What's the best method? Quote Link to comment
JonathanM Posted December 6, 2022 Share Posted December 6, 2022 Add 2 pools each with a single SSD in them. Quote Link to comment
tucansam Posted December 6, 2022 Author Share Posted December 6, 2022 No idea whatsoever what that even means, but I'm off to research. Quote Link to comment
