sorry i can't post output of `pveversion -v` but i can't run df on the main node . the node he can' see any disks mounted or her disks local ! maybe it is the problem !?
journalctl: command not found ?
but i have in /var/log/syslog
"Load average increasing, re-enabling all cpus for irq balancing" And
"Traffic rate for "xxxxx" higher than set maximum xxx Mbit"
