[lustre-discuss] Strange lustre 2.7 client behavior

[Jérôme BECOT]

I have downgraded machines causing the issue to 2.7.0.1 client

It doesn't have the folder issue, but

in 2.7.65 : The ls -l command issued in a script by the nrpe agent cause 
the "lustre-MDT0000-mdc-ffff88032e4cb000: operation ldlm_enqueue to node 
10.0.1.60 at tcp failed: rc = -14" error in the logs
in 2.7.0 : The command doesn't cause the error on standard client, 
however clients with a preceding 2.7.65 version still triggers this 
error until the servers are restarted

The ls -l launched several times in a terminal does not triggers the 
error nor the nrpe script with a simple ls.

As I didn't have any answer for the ldlm_enqueue error in my precedent 
email, I do not expect any answer though I just want to give an update 
(if someone else face this problem some day)

Regards
