B_ISC Posted January 21, 2020 Share Posted January 21, 2020 I'm running the latest 6.8.1 (problem existed in 6.8.0) and have a btrfs cache pool (mirrored identical 120GB SSDs) that initially showed 75GB used, I confirmed they are almost EMPTY through the SMB cache share and through SFTP...I first ran the mover script a few times, still no change, then thinking it could just be a glitch, I rebooted unraid, and it now shows 111GB USED...verifying through the SMB cache share, still only a few GB are used. Is this a BTRFS issue or an unraid issue? Are there files on the share that possibly would not show up in an SMB listing or an SFTP? listing? Quote Link to comment
bonienl Posted January 21, 2020 Share Posted January 21, 2020 (edited) What is the output of df -H /mnt/cache And this btrfs filesystem show /mnt/cache Edited January 21, 2020 by bonienl Quote Link to comment
B_ISC Posted January 21, 2020 Author Share Posted January 21, 2020 Thank you for the help...The df works, but I used "sudo du /mnt/user/system..." for each of the folders on the cache and found the full size docker image being recreated, it looks like the the docker image is not counted in the file size listing via smb/sftp, and somehow (me or automatic) the docker image initial size was set to 100GB (which explains the reboot, but not before the reboot). I disabled docker, deleted the image and everything is empty again. does docker.img have different permissions causing smb shares not to list it? For the future, is there an easy way to store the docker image/each docker data to the array instead of the cache drive? Thank you for your help! Quote Link to comment
B_ISC Posted January 21, 2020 Author Share Posted January 21, 2020 NM...batting a thousand this afternoon...settings for storage locations right in the docker settings...oops. Quote Link to comment
bonienl Posted January 21, 2020 Share Posted January 21, 2020 You want to keep the docker image on your cache (SSD). If placed on the array it has a significant impact on the performance of the docker applications. Usually a size of 20GB is more than enough for the docker image. Quote Link to comment
B_ISC Posted January 21, 2020 Author Share Posted January 21, 2020 If a docker app stores it's data in the appdata location, what else would be stored in the docker image? Quote Link to comment
