Host operating system:

Linux css 4.4.68-nx #122 SMP Mon May 15 09:46:11 KST 2017 x86_64 GNU/Linux

node_exporter version:

  build user:       root@bb6d0678e7f3
  build date:       20170321-12:12:54
  go version:       go1.7.5

Are you running node_exporter in Docker?

yes

What did you do that produced an error?

With given query below

node_filesystem_size{instance=~"(css).*",fstype=~"(ext4|xfs)",mountpoint!~".*mapper.*",device!~".*mapper.*"}

Result is

node_filesystem_size{device="/dev/sda1",fstype="ext4",instance="css:9100",job="node",mountpoint="/rootfs"}	21003628544
node_filesystem_size{device="/dev/sda3",fstype="ext4",instance="css:9100",job="node",mountpoint="/rootfs/home"}	857421250560
node_filesystem_size{device="/dev/sda3",fstype="ext4",instance="css:9100",job="node",mountpoint="/rootfs/home1"}	857421250560

Actually second record is bind mounted point. If I can get mount options it would be helpful, to exclude the record.
