    Description

      File creates are not tracked on the MDS in the md_stats file:

      # lctl set_param mdt.*.md_stats=clear
mdt.lustre-MDT0000.md_stats=clear
# touch /mnt/lustre/newfile1
# lctl get_param mdt.*.md_stats
mdt.lustre-MDT0000.md_stats=

open                      1 samples [reqs]
close                     1 samples [reqs]

setattr                   1 samples [reqs]
getxattr                  1 samples [reqs]
setxattr                  1 samples [reqs]

      If you call mknod() with S_IFREG to create a file, it is tracked as a mknod. Most file creates are from open with create intent.
