Description of problem:
If glance is deployed with NFS backend the mounts are dropped during FFU. The issue is not immediately apparent as /var/lib/glance from local disk will be used, however as the image does not exist on all controllers deploying VM instances will fail randomly (succeeds if it happens to pull the image from the controller that it was uploaded to).
I assume nova-compute has a similar issue when using NFS backend.
After controller 17.1 upgrade:
[cloud-admin@controller-2 ~]$ cat /etc/fstab
UUID=a978a857-eaf9-4fec-a61d-0b790b27f097 / xfs defaults 0 0
UUID=7B77-95E7 /boot/efi vfat defaults,uid=0,gid=0,umask=077,shortname=winnt 0 2
172.22.0.1:/home/nfs/glance /var/lib/glance/images nfs _netdev,bg,intr,context=system_u:object_r:svirt_sandbox_file_t:s0 0 0
After leapp RHEL 9.2 upgrade:
[cloud-admin@controller-2 ~]$ cat /etc/fstab
UUID=a978a857-eaf9-4fec-a61d-0b790b27f097 / xfs defaults 0 0
UUID=7B77-95E7 /boot/efi vfat defaults,uid=0,gid=0,umask=077,shortname=winnt 0 2
