April 14, 20197 yr Hello. My cache drive is throwing "no space left on device". When I do a df -h, I get: Filesystem Size Used Avail Use% Mounted on /dev/sdb1 239G 85G 0 100% /mnt/cache It's running btrfs. I have done a trim, did a btrfs scrub. No luck. Any thoughts?

April 14, 20197 yr What version? There's other manual commands you need to run on older unraids for BTRfs since it really wasn't ready for general use. Newer kernals with newer BTRfs may have addressed that issue. Then again, it might be some other BTRfs issue. I'm sure @johnnie.black will drop his knowledge on the issue(s) when he can.
April 14, 20197 yr Also, these cmds are more meaningful for BTRfs since its special... btrfs fi us /mnt/cache btrfs fi show /mnt/cache btrfs filesystem df /mnt/cache ....... Also, I think Johnnie will have you run some sort of cmd that looks like the following, I dint know their exactness but this is something to give you a heads up. Caveat: dont run these specific examples that I typed out but wait for the exact cmds from Johnnie. btrfs balance start -m /mnt/cache Btrfs balance start -dusage=5 /mnt/cache
