[lustre-discuss] the .lustre/fid special directory

Greetings Assembled Wisdom!
I have a question regarding the special directory found on a Lustre File
System mount point ".lustre/fid".
I have several Lustre File Systems currently running
2.7.19.8-3.10.0_514.2.2 on CentOS 7.3.1611 each of which has its Lustre
mountpoint, say /mnt/Dev1, /mnt/Dev2, for example.
On each of these mount points I have the special directory:
/mnt/Dev1/.lustre:
dr-x------ 2 root root 25088 Jan 1 1970 lost+found
d--x------2 root root 25088 Jan 1 1970 fid
drwxr-xr-x 7 root root 25088 Jan 19 21:11 ..
Yes, each Lustre mount point has the "Jan 1 1970" date on those dirs.
The command "ls -l /mnt/Dev1/.lustre/fid" returns nothing, not even a
permission error.
I am asking because my newly upgraded version of Robinhood Policy Engine
3.1 (from 3.0), now shows an error "_set_mount_point | Error: failed to get
FID for special directory </mnt/Dev1/.lustre/fid>: Permission denied when I
execute a "rbh-report" command.
Other than this new error on the Robinhood server, everything else is
occurring normally. I am seeing what I believe to be correct Robinhood
database information.
- Is this /mnt/Dev1/.lustre special directory supposed to have these
unusual dates associated with the directories?
- Is this /mnt/Dev1/.lustre special directory supposed to have the unusual
permissions associated with sub-dirs?
Could this be related to LU-10243? (I cannot get to that bug to view any
details yet.)
Cheers,
megan
