monkiefone Posted October 9, 2017 Share Posted October 9, 2017 HI Everyone. I'm asking for help again! All my docker apps disappeared after a power cut here last week. I followed Squids excellent advise to delete the corrupted Docker image and reinstall the apps. All worked fine for a week or so until all the docker apps stopped and would not restart. I deleted the docker image again and started reinstalling the apps but I now get an error when installing.

monkiefone Posted October 9, 2017 Author Share Posted October 9, 2017 Further to this, when the mover runs I get this error for what looks like every file on the array! Quote Link to comment

MowMdown Posted October 9, 2017 Share Posted October 9, 2017 (edited) Quote devid 1 size 55.90GiB used 55.90GiB path /dev/sdg1 This tell me that the cache has been fully allocated ^ You'll need to run: btrfs balance start -dusage=5 /mnt/cache and once that is finished, run the previous two commands and post the results again. Edit: Here is an explaination on whats happening. Edited October 9, 2017 by MowMdown Quote Link to comment

Not combined. Quote Link to comment
JorgeB Posted October 9, 2017 Share Posted October 9, 2017 Your out of space on your cache, when using different size devices the free space is incorrectly reported, your max usable space is 60GB. 1 Quote Link to comment
MowMdown Posted October 9, 2017 Share Posted October 9, 2017 (edited) I see whats going on, You're running RAID1 which is mirroring, your smallest disk is a 60GB disk and you've used 55.9GiB which is pretty much 60GB not sure why 90GB is shown but I don't belive that is accurate, it should read 60GB Paging @johnnie.black, he might have a solution to regain your cache. I don't use a cache pool (single 250Gb for me) Edit: Johnnie beat me too it. Edited October 9, 2017 by MowMdown Quote Link to comment
JorgeB Posted October 9, 2017 Share Posted October 9, 2017 If you want to keep the raid1 profile free up space or convert to single profile and you can use the space of both combined: Quote Link to comment
monkiefone Posted October 10, 2017 Author Share Posted October 10, 2017 Thank you, everyone. I have sorted it! I have taken the cache pool out of Raid 1 and put it in Raid 0 for now. I've changed where Plex now stores its metadata and I've just ordered a new 1tb SSD as a new cache drive as these are far too small. Quote Link to comment
JorgeB Posted October 10, 2017 Share Posted October 10, 2017 Raid0 doubles the available space, but note that you'll only have 120GB usable and the free space will still be incorrectly reported, only the single profile can use the combined 180GB. 1 Quote Link to comment
monkiefone Posted October 10, 2017 Author Share Posted October 10, 2017 Thank you. I'm only going to run this setup for a couple of days until the new drive shows up. thank you again for your help. Quote Link to comment
