May 16, 20197 yr not sure what happened but overnight a cache drive got dropped from pool when i rebooted i got a message about too many profiles and my 500gb cache pool was now 1TB so i found a topic that stated to run a balance. after 1st balance nothing happened so i rebooted. when system came back up a 2nd balance started and when completed was back at 500gb. although all my containers/shares kept saying low on storage when more than half should be avialable. i rebooted once more and now my cache pool is 250gb with a 3rd balance started. not sure whats going on lol is this something common or something i shouldnt be to worry about?? if anything i could just wipe drives clean and start anew EDIT: 4th balance completed and rebooted and still stuch at 250gb heres what i have at the moment btrfs fi df /mnt/cache Data, DUP: total=228.86GiB, used=215.57GiB System, single: total=32.00MiB, used=64.00KiB Metadata, DUP: total=3.00GiB, used=2.56GiB GlobalReserve, single: total=352.70MiB, used=0.00B Edited May 17, 20197 yr by Furby8704
May 16, 20197 yr Community Expert Looks normal to me: Filesystem Size Used Avail Use% Mounted on /dev/sde1 466G 272G 193G 59% /mnt/cache Can you post a screenshot of the main GUI page?
May 16, 20197 yr Author main gui of cache and nzbget stats are attached both showing 250GB with 13gb left also dashboard shows cache 2 in pool is in stand by Edited May 16, 20197 yr by Furby8704
May 16, 20197 yr Community Expert Currently only one device is part of the pool, despite two being assigned, and it's using the DUP profile, hence the half space. Stop the array, unassign cache2, start the array, stop the array, re-assign cache2 and start the array. After Unraid finishes balancing convert pool to raid1: btrfs balance start -dconvert=raid1 -mconvert=raid /mnt/cache

May 17, 20197 yr Community Expert do you know what happened or what i did to have caused this?? Not sure since the logs don't cover it, but problem likely started because cache2 dropped offline, but Unraid would't convert the cache to DUP profile on its own.
