Tips and Trics

Hostname & FQDN

Make sure the hostname and fqdn are properly set. If this is not set properly this might result in performance degradation or ghost services; for example Ceph Monitor, Manager and Metadata Servers.

$ hostname
pve0
$ hostname -f
pve0.siempie.local
$ hostname -d
siempie.local

Maintenance mode

sudo ha-manager crm-command node-maintenance enable pve0

sudo ha-manager crm-command node-maintenance disable pve0

Show running VMs

sudo qm list
