This is kind of strange (kernel 4.6.3, Ubuntu 16.04):
# mount -t btrfs /dev/sda4 /home
# echo $?
0
# dmesg -c
[382148.588847] BTRFS info (device sda4): disk space caching is enabled
[382148.588851] BTRFS: has skinny extents
So it worked?
# ls /home
<empty, should be showing data>
# df | grep home
# mount | grep /home
# lsof -n | grep /home
All give no output.
So, weird, isn't it?
Now, let's try to mount to /home2:
# mkdir /home2
# mount /dev/sda4 /home2
# mount | grep home
/dev/sda4 on /home2 type btrfs
(rw,relatime,space_cache,subvolid=5,subvol=/)
# dmesg -c
[382190.199363] BTRFS info (device sda4): disk space caching is enabled
[382190.199370] BTRFS: has skinny extents
What's wrong there?
