3. yesterday i added a job to backup all vms at night but this morning i found my proxmox system unresponsive, i had to reset the machine.
i found that it finished with the first vm but hunged at second, left it locked.

thank you
u.
 
we will upload new package with a lot of fixes regarding backup soon (tomorrow).
 
thank you Tom,

please help me how to clean all backup jobs, i don't see them in the gui
 
after this mornings upgrade, I can now see the backup vzdump jobs, but can not edit or delete.

on pve web page: "unable to open file '/etc/pve/vzdump.cron.tmp.4323' - Permission denied (500)"

and cli listing or /etc/pve shows perms :

what is the output of

# pvecm status

(maybe you do not have quorum?)
Click to expand...


yes there was this at fbc158 console at boot:
Code: 
Starting cluster:
   Checking if cluster has been disabled at boot... [  OK  ]
   Checking Network Manager... [  OK  ]
   Global setup... [  OK  ]
   Loading kernel modules... [  OK  ]
   Mounting configfs... [  OK  ]
   Starting cman... [  OK  ]
   Waiting for quorum... Timed-out waiting for cluster
[FAILED]
Starting OpenVZ: ..done

then the data you asked for:
Code: 
root@homenet-fbc158 /etc/lvm # pvecm status
Version: 6.2.0
Config Version: 4
Cluster Name: fbcandover
Cluster Id: 37452
Cluster Member: Yes
Cluster Generation: 6656
Membership state: Cluster-Member

Node name: fbc158
Node ID: 1
Multicast addresses: 239.192.146.222 
Node addresses: 10.100.100.158

and on the other node fbc10:
Code: 
root@homenet-fbc10 /etc/pve # pvecm status
Version: 6.2.0
Config Version: 4
Cluster Name: fbcandover
Cluster Id: 37452
Cluster Member: Yes
Cluster Generation: 4

Node name: fbc10
Node ID: 2
Multicast addresses: 239.192.146.222 
Node addresses: 10.100.100.6

I see 10.100.100.6 , which is not the main address.. I added that to interfaces :
Code: 
auto vmbr0
iface vmbr0 inet static
        address  10.100.100.10
        netmask  255.255.255.0
        gateway  10.100.100.2
        bridge_ports eth0
        bridge_stp off
        bridge_fd 0



# 2011-11-26  dhcp needs
auto eth0:1
iface eth0:1  inet static
    address 10.100.100.6
    netmask 255.255.0.0

so I'll remove the 10.100.100.6 address for now. I added it to use the same dns server address on 2 different setups [ in order to try to use the same dhcpd.conf , but I'll configure dhcp differently...].
