Syslog errors when creating a cluster. How can i stop from flooding my log file ? Mar 1 20:20:57 host153 pmxcfs: [status] crit: cpg_send_message failed: 9 Mar 1 20:20:57 host153 pmxcfs: [dcdb] notice: cpg_join retry 1740 Mar 1 20:20:57 host153 corosync: [TOTEM ] Totem is unable to form a cluster because of an operating system or network fault. The most common cause of this message is that the local firewall is configured improperly. Mar 1 20:20:58 host153 pmxcfs: [dcdb] notice: cpg_join retry 1750 Mar 1 20:20:59 host153 pmxcfs: [dcdb] notice: cpg_join retry 1760 Must be my firewall. But it seems Totem is trying form a cluster. How can i stop this process ? Also get error No ticket (401) When start a VM !?? unable to open file '/etc/pve/nodes/host153/qemu-server/100.conf.tmp.1034226' - Permission denied ???
