Hm... It seems that I missed the complain about libibverbs.so.1 which is part of package libibverbs-22.1-3.el7.x86_64 .

Once I have deployed that, no more issues are observed.

I guess there is a missing dependency.

Hello Community,

I was waiting for 7.7 to come up before I upgrade my lab.

The engine got upgraded  without issues, same for OS - but after the system powered up I receive the  following:

[root@ovirt1 ~]# ssh engine root@engine's password: Last login: Wed Sep 18 19:48:32 2019 from ovirt1.localdomainnet_mlx5: cannot load glue library: libibverbs.so.1: cannot open shared object file: No such file or directory net_mlx5: cannot initialize PMD due to missing run-time dependency on rdma-core libraries (libibverbs, libmlx5) PMD: net_mlx4: cannot load glue library: libibverbs.so.1: cannot open shared object file: No such file or directory PMD: net_mlx4: cannot initialize PMD due to missing run-time dependency on rdma-core libraries (libibverbs, libmlx4) net_mlx5: cannot load glue library: libibverbs.so.1: cannot open shared object file: No such file or directory net_mlx5: cannot initialize PMD due to missing run-time dependency on rdma-core libraries (libibverbs, libmlx5) PMD: net_mlx4: cannot load glue library: libibverbs.so.1: cannot open shared object file: No such file or directory PMD: net_mlx4: cannot initialize PMD due to missing run-time dependency on rdma-core libraries (libibverbs, libmlx4) [root@engine ~]#

Anyone else experiecing this  ? I can't find libmlx4  or libmlx5 in the repos.

P.S.: I have a gluster  snapshot, so I can rollback if needed. For now I will postpone  my hosts' upgrade.
