Hello All :)

Completely newbie in terms of PMVE virtualization world I inherited a two node proxmox ve environment with ZFS storage replication between those two. Everything went smoothly until yesterday when I had to power off both hosts. After powering on I get into weird situation where:
1. PM01 started and I could ssh into but when going to web console I was unable to login because of "login failed" message
2. PM02 tried to start but constantly get into Kernel Panic (I restarted it like 2-3 times):

But when I started it from different kernel (?) where I chose Advanced options for Proxmox VE at start and then chose PX VE with Linux 5.15.30-2-PVE I got this:
PM02 aleternate kernel started.png

and suddenly everything start working - I was able to web login to PM01and PM02 also started fully and I was able to login into web console. All VMs on both nodes are running now.
Can You support me and tell what in fact happened or where to check it ?

best regards
