Hi Christoph,
I am able to reproducibly kernel panic CentOS 7 clients with native
kernel (3.10.0-1160.76.1.el7) when accessing CephFS snapshots via SMB
with vfs_shadow_copy2. This occurs on a Pacific cluster. IIRC accessing
the snapshots on the server also lead to a kernel panic, but I'm not sure.
Running a mainline kernel from elrepo prevents this issue.
I imagine that you might possibly run into these issues with a Quincy
cluster as well, if you are using CephFS snapshots at all.
Cheers
Sebastian

Hello all,
i would like to upgrade our well running Rocky 8.6 based bare metal cluster
from Octopus to Quincy next few days. But there are some Centos7 Kernel
based clients mapping RBDs or mounting CephFS in our environment.
Is there someone here who can confirm Centos 7 clients
(3.10.0-1160.76.1.el7.x86_64) working with Quincy?
Best regards,
Christoph
