[LU-1319] MDT getattr stats not getting updated

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.3.0, Lustre 2.1.2
• Affects Version/s: Lustre 2.0.0, Lustre 2.1.0, Lustre 2.2.0, Lustre 2.3.0, Lustre 2.1.1, Lustre 2.1.2
• Severity: 3

Description

The MDT getattr statistic in procfs is not incremented when clients perform stat operations on files. For example,

$ echo clear | sudo tee /proc/fs/lustre/mdt/lustre-MDT0000/md_stats
clear
$ grep getattr /proc/fs/lustre/mdt/lustre-MDT0000/md_stats
$ sudo touch /mnt/lustre/test
$ ls -l /mnt/lustre/test
rw-rr- 1 root root 0 Apr 12 17:42 /mnt/lustre/test
$ grep getattr /proc/fs/lustre/mdt/lustre-MDT0000/md_stats
$

Should getattr get incremented in this case?
