[LU-9310] kernel update [RHEL7.3 3.10.0-514.10.2.el7] for lustre 2.7 client

• Type: Bug
• Resolution: Fixed
• Priority: Major
• Affects Version/s: Lustre 2.7.0
• Environment: RHEL7 clients with a file system based on RHEL6 servers.
• Severity: 3
• Assignee: Bob Glossman (Inactive)
• Reporter: Frederik Ferner (Inactive)

Description

We are now deploying the first production servers (lustre clients) based on RHEL7 and would want to update to the latest RHEL7 kernel (3.10.0-514.10.2.el7) but trying to build lustre 2.7-fe for this kernel fails with the error below. We have successfully build the client RPMs for earlier kernels (tested up to3.10.0-327.36.3.el7) .

As our file system currently is 2.7(.3) based, we would quite like to continue deploying 2.7 clients but need help identifying the necessary patches.

Build error for latest kernel:
