      Description

      Since we upgraded Sherlock compute nodes from Lustre client 2.12 LTS to Lustre client 2.13.0, we're seeing the following error messages on the 2.13 clients:

      It is only happening with Oak which is still running Lustre 2.10.8 (servers), not with Fir which is running Lustre 2.12.3_4 (servers).

      It's unclear if this has a negative impact. Oak is accessible and seems to work as expected. The error messages are a bit annoying though.

      Thanks!
