October 3, 20178 yr I've noticed that on my 250GB Samsung Evo cache drive that 104GB is used at all times. There is nothing that I can see that has to be moved to the array. I've used the likes of cadvisor to see if there were rogue log files building up etc but it doesn't show anything out of the ordinary. I've also ssh ed into the server and used various commands to list biggest files on the server etc but again nothing seems to be showing up. Is there something blatantly obvious that I'm missing? I am only running five docker containers which are as follows: Sabnzbd Sonarr Couchpotato EmbyServer cadvisor Here is a attachment of my container mappings? Maybe I've mapped something incorrectly? If anyone can help me solve this it would be very much appreciated.
October 3, 20178 yr The only thing I see is that CP, SAB & Sonarr all point to /mnt/cache/Downloads are you sure they're not busy filling up the disk with downloaded files?
October 3, 20178 yr Hi, There's a few things I'd look at to check the issue. I'm not sure what commands you have run, but I'd start by ssh root@servername and login. Then I'd look at the file sizes specifically for the cache drive. First I'd see what you get when you type: df -h /mnt/cache This should give you info about the disk in standard numbers (-h human readable) I don't use a cache drive but I'd expect it will show you that you've got a 250GB(ish) drive and however much is used/free. Next to figure out what is using this data (provided the drive shows up as expected above.) du -h --max-depth 1 /mnt/cache This should list the size of the directories on that drive - hopefully this will get you closer. If you note a specific directory which looks strangely large you can use that same command on that directory, so for example: du -h --max-depth 1 /mnt/cache/appdata (or whichever folder seems to be the issue.) Obviously, you can adjust the --max-depth number to suit your needs. Hopefully this will help you narrow down where your drive space is going. Del Edited October 3, 20178 yr by Delarius
October 4, 20178 yr Author @DelariusIve run the command and I still dont see anything overly out of the ordinary. Here is the output from two variations of the command. Would you be able to have a look at this for me? du -h --max-depth 1 /mnt/cache 4.6G /mnt/cache/appdata 1.3G /mnt/cache/Downloads 16G /mnt/cache du -h --max-depth 3 /mnt/cache 896K /mnt/cache/appdata/sabnzbd/admin 0 /mnt/cache/appdata/sabnzbd/logs 916K /mnt/cache/appdata/sabnzbd 1.2M /mnt/cache/appdata/cache/images 1.4M /mnt/cache/appdata/cache/python 3.2M /mnt/cache/appdata/cache 0 /mnt/cache/appdata/backup 0 /mnt/cache/appdata/logs 80K /mnt/cache/appdata/database/_indexes 1.9M /mnt/cache/appdata/database 4.0K /mnt/cache/appdata/custom_plugins 264K /mnt/cache/appdata/db_backup 79M /mnt/cache/appdata/sonarr/MediaCover 8.2M /mnt/cache/appdata/sonarr/Backups 2.5M /mnt/cache/appdata/sonarr/logs 111M /mnt/cache/appdata/sonarr 12M /mnt/cache/appdata/couchpotato/database 166M /mnt/cache/appdata/couchpotato/cache 4.0K /mnt/cache/appdata/couchpotato/custom_plugins 7.1M /mnt/cache/appdata/couchpotato/db_backup 200K /mnt/cache/appdata/couchpotato/logs 184M /mnt/cache/appdata/couchpotato 4.0K /mnt/cache/appdata/scripts/nzbget 4.0K /mnt/cache/appdata/scripts/sabnzbd 16K /mnt/cache/appdata/scripts 5.3M /mnt/cache/appdata/EmbyServer/logs 2.0G /mnt/cache/appdata/EmbyServer/cache 456K /mnt/cache/appdata/EmbyServer/config 80K /mnt/cache/appdata/EmbyServer/localization 154M /mnt/cache/appdata/EmbyServer/data 4.0K /mnt/cache/appdata/EmbyServer/ssl 88M /mnt/cache/appdata/EmbyServer/ffmpeg 16K /mnt/cache/appdata/EmbyServer/root 2.1G /mnt/cache/appdata/EmbyServer/metadata 1.2M /mnt/cache/appdata/EmbyServer/plugins 0 /mnt/cache/appdata/EmbyServer/transcoding-temp 116K /mnt/cache/appdata/EmbyServer/fonts 0 /mnt/cache/appdata/EmbyServer/sync 4.3G /mnt/cache/appdata/EmbyServer 4.6G /mnt/cache/appdata 12K /mnt/cache/Downloads/downloads/incomplete 1.1G /mnt/cache/Downloads/downloads/complete 1.2G /mnt/cache/Downloads/downloads 0 /mnt/cache/Downloads/tmp/transcoding-temp 0 /mnt/cache/Downloads/tmp 1.3G /mnt/cache/Downloads 16G /mnt/cache
October 4, 20178 yr Author Hi, @tdallenthanks for taking a look. df -h /mnt/cache Filesystem Size Used Avail Use% Mounted on /dev/sdg1 233G 181G 52G 78% /mnt/cache At the moment there is a 52gb linux iso() downloading to the cache drive.
October 4, 20178 yr That all looks good. I think there’s something else that’s marked as deleted but isn’t. Could you try: lsof | grep /mnt/cache With luck that’ll show all files open on that drive - see if that helps. You could also check for files that are tagged as deleted, lsof | grep -i deleted If that doesn’t help, try fsck on that drive? I think you can also check btrfs from the GUI under disk management when array is in maintenance mode. Edited October 5, 20178 yr by Delarius Fixing words

October 5, 20178 yr Author UPDATE I took a notion to stop the array and start it again in maintenance mode and ran "Check Filesystem Status" and magically my 100GB appeared back. It now shows I'm only using 23gb which is about right. Don't understand how or why but I'm just glad the missing space is back. Thanks very much for all of the assistance guys. This forum is one of the main reasons I use unRaid, the support network is phenomenal. Thanks again!
