[LU-11133] lustre-ldiskfs-dkms package does not provide the ldiskfs kernel module

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.12.0
• Affects Version/s: Lustre 2.11.0, Lustre 2.12.0, Lustre 2.10.4
• Environment: RHEL 7.5, dkms
• Severity: 3
• Assignee: Nathaniel Clark
• Reporter: Sebastien Piechurski

Description

While experimenting with the dkms package for lustre to implement a patchless server, I saw that the lustre-ldiskfs-dkms package does not provide the ldiskfs.ko module. It does provide the osd-ldiskfs module however.

When playing the "dkms build" command, the logs  show that the module is actually generated, but not copied in the dkms tree after that.

It would seem the following lines are missing to the dkms.conf file:
