Kernel panic on DRBD 9.2.11 #198

Closed maxpain closed 4 days ago

maxpain commented 5 days ago

I have kernel panic almost every day. In rare cases, it happens on multiple nodes at the same time. I use the DRBD 9.2.11 extension in Talos Linux v1.8.2 (Linux 6.6.58) on bare metal nodes (Dell R6615) with NVMe SSD. I use Piraeus Operator on my Kubernetes cluster.

For the network, I use Broadcom 2x25G (50G in LACP bonding) with MTU 9000 (jumbo frame). Linstor satellite pods are deployed with hostNetwork: true.

I'm unsure where to create an issue, so I've created there as well.
