Hi,

You need three nodes for a cluster. With two nodes, and a reboot of one 
of the two, the remaining node has no quorum and will do nothing.

Best solution is to get a third node, or external vote support : 
https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_corosync_external_vote_support

Also, check the shutdown policy: 
https://pve.proxmox.com/pve-docs/pve-admin-guide.html#ha_manager_shutdown_policy

Good luck!

Subject [PVE-User] 8.2.2 - limited cluster functionality

>Hello to all,
>
>I've installed PVE cluster (ver 8.2.2) , two nodes : pve01 / pve02 put in HA group G1
>
>Every VM has "started" state ..   When i.e. PVE02 node  restarts , it's VMs are not being migrated to PVE01 node, but they get in "freeze" state in stead of being (online) migrated to PVE01 node ... Syslog messages are "shutting down"
>
>  ....  VMs are started again just after PVE02 node boots up ... So , real downtime can be experienced
>
>Otherwise , manual online migration works correctly (zfs storage replication)
>
>  Could somebody check this ?

>Thank you very much in advance
