Summary0016046: libvirt not recognising GPFS as shared filesystem
DescriptionAfter our migration to CentOS 7.6, we are no longer able to do live-migration for VMs with our OpenStack installation, due to the fact that GPFS is not recognised as a shared filesystem in pre-migration steps anymore.

The same issue was there for Ceph, and was fixed already via Patch (see https://git.centos.org/rpms/libvirt/blob/c7/f/SOURCES/libvirt-virfile-Detect-ceph-as-shared-FS.patch)
For GPFS there is also a upstream bug-fix available (see https://github.com/libvirt/libvirt/commit/d163b940a73a0d6b8277a4bccef2b60936933cf0)

The logs that we receive within OpenStack:
