hi,
I have an 80GB external HDD with one btrfs partition. Latest kernel
module and btrfs-progs from "unstable" git repos.
# mount
[...]
/dev/sdb1 on /media/coolermaster type btrfs (rw)
# df -h
[...]
/dev/sdb1 75G 61G 15G 81% /media/coolermaster
It seems like i have 15GB free space on the btrfs formatted partition,
but when i try to create a file of 4GB on the btrfs filesystem i get the
following error:
root@alderaan:/media/coolermaster/tmp# dd if=/dev/zero of=foobar.img
bs=1024 count=4000K
dd: writing `foobar.img'': No space left on device
3372894+0 records in
3372893+0 records out
3453842432 bytes (3.5 GB) copied, 321.087 s, 10.8 MB/s
syslog:
Dec 8 10:35:46 alderaan kernel: [30716.434747] device fsid
46489b7e62f254e0-e306291dd7724d8f devid 1 transid 283 /dev/sdb1
Dec 8 10:35:50 alderaan kernel: [30720.457774] space info full 36
Am i missing something (e.g. reserved space for root, etc.) obvious
here?
Thanks,
