Message-ID: <20170628055914.GA11753@localhost> (raw)

Hi! I test on my host and find below issue, i want to know how can fix it?

root@ubuntu ~/xfstests# ./check generic/015
FSTYP         -- btrfs
PLATFORM      -- Linux/x86_64 ubuntu 4.12.0-rc6
MKFS_OPTIONS  -- /dev/sda2
MOUNT_OPTIONS -- /dev/sda2 /fs/scratch

I print _free to log and find after rm, the space do not free:

root@ubuntu ~/xfstests# cat log
/dev/sda2      btrfs       51200 16416     46052      27% /fs/scratch

/dev/sda2      btrfs       51200 46144     17348      73% /fs/scratch
17348

It makes me confused, and i am sure the file has removed and can not create size over 17348 file.
Is it a bug or something wrong with my host?

Thanks
Dai Xiang
