I have cephFS cluster. Below is the df from a client node. Question is why does the df command when mounted using ceph-fuse or ceph-kernel mount shows "used space" when there is nothing used(empty -- no files or directories)
[root@storage ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/centos-root 45G 1.4G 44G 4% / devtmpfs 28G 0 28G 0% /dev tmpfs 28G 0 28G 0% /dev/shm tmpfs 28G 17M 28G 1% /run tmpfs 28G 0 28G 0% /sys/fs/cgroup /dev/xvda1 497M 168M 329M 34% /boot /dev/mapper/centos-home 22G 34M 22G 1% /home tmpfs 5.5G 0 5.5G 0% /run/user/0 ceph-fuse 4.7T 1.5G 4.7T 1% /mnt/cephfs [root@storage ~]# [root@storage ~]# ls -larth /mnt/cephfs/ total 512 drwxr-xr-x. 3 root root 19 Mar 17 12:36 .. drwxr-xr-x 1 root root 0 Mar 23 22:20 .
