Description

We have a process that periodically does a lfs quota throughout the day to monitor the usage on our file system. Recently we have started observing that while the usage numbers are being reported, the number of files that are reported for a given user went from a given number (e.g., 100,000 files) to 0 or 1.

This has persisted through system reboots and a OS/Lustre update. Once the given user's file count is reported as 0 or 1 it never changes. However checking the quota for the user's GID will generate a file count.

Anecdotally, it appears that only users that are affected are those that have files that have mixed user and group IDs.

All the normal checks have been performed (i.e., consistency of UID/GID in the password files between the file servers and clients, checking the MDT for ownership, checking file count with ls -l, etc.). It almost appears that an error condition is being flagged that needs to be cleared.
