[Linux-cluster] gfs_tool df question

[Bowie Bailey]

I am trying to understand the information provided by "gfs_tool df".

When I run it on my system, I get this:

  Type           Total          Used           Free           use%
  ------------------------------------------------------------------------
  inodes         2697580        2697580        0              100%
  metadata       104195         21410          82785          21%
  data           290040505      23167          290017338      0%

I figured out that the data row is reporting used and free space in
blocks and the inode row is self-explanatory, but what is "metadata"?
Do I need to be concerned that metadata is 21% used while data hasn't
even hit 1% yet?
