Hello,
currently, I suffer of a weird problem with a btrfs filesystem: ~> uname -r 4.0.9 ~> stat -f / File: "/" ID: a446833a80ceeb6a Namelen: 255 Type: btrfs Block size: 4096 Fundamental block size: 4096 Blocks: Total: 128472 Free: 41964 Available: 42981 Inodes: Total: 0 Free: 0
As you can see, f_bavail is slightly bigger than f_bfree. As I understand the values, f_bavail should be never bigger than f_bfree.
Currently that breaks check_disk from nagios.
How can that happening? I found a thread about some try to make f_bavail more accurate in 2014 but nothing about f_bfree.
What I didn't try until now, is, if that problem also happened with the most recent kernel version but this will be my next step.
Please forgive that I don't read lkml regularly. Please keep me in Cc for this reason.
