Still, 45 gigs should be free there. If those 45 gigs aren't really there then it shouldn't say they are there, imho. > That said, I'd be interested to know why btrfs fi show /dev/sda3 shows > 412.54G used, but btrfs fi df /home shows 379G used... The former also says "bytes used 371.11GB" and there's not *that* much difference between "371.11" and "369.61" gigs. The devid line seems to always say "412.54GB used 412.54GB" no matter how much is actually in use. I have no idea what these numbers actually mean. > On 02/25/2014 11:49 AM, Marcus Sundman wrote: >> Hi >> >> I get "No space left on device" and it is unclear why: >> >>> # df -h|grep sda3 >>> /dev/sda3 413G 368G 45G 90% /home >>> # btrfs filesystem show /dev/sda3 >>> Label: 'home' uuid: 46279061-51f4-40c2-afd0-61d6faab7f60 >>> Total devices 1 FS bytes used 371.11GB >>> devid 1 size 412.54GB used 412.54GB path /dev/sda3 >>> >>> Btrfs v0.20-rc1 >>> # btrfs filesystem df /home >>> Data: total=410.52GB, used=369.61GB >>> System: total=4.00MB, used=64.00KB >>> Metadata: total=2.01GB, used=1.50GB >>> # >> >> So, 'data' and 'metadata' seem to be fine(?), but 'system' is a bit >> low.
