[lustre-discuss] Lustre 2.10 and RHEL74

[Riccardo Veraldi]

I have the kabi whitelist package on hte system:

kernel-abi-whitelists-3.10.0-693.1.1.el7.noarch

I also built the rpm without ldiskfs support because I Am using ZFS.

the problem seems to be with  kmod-lustre-osd-zfs

If so, then you can either remove the “vfs-project-quotas-rhel7.patch” from the patch series for the server kernel (which will remove project quota support), or disable the kabi check when compiling the kernel.
