/etc/pve: Device or resource busy

[decibel83]

Hi.
I'm in trouble using a 10 nodes PVE cluster.
All nodes seems to be correctly connected:

[B]root[/B][B]@[/B][B]ve10 [/B][B]~ [/B][B]# [/B]pvecm nodes
Node  Sts   Inc   Joined               Name
   1   M  135792   2014-01-21 21:58:03  ve2
   2   M  135792   2014-01-21 21:58:03  ve7
   3   M  135792   2014-01-21 21:58:03  ve9
   4   M  135792   2014-01-21 21:58:03  ve8
   5   M  135792   2014-01-21 21:58:03  ve1
   6   M  135792   2014-01-21 21:58:03  ve6
   7   M  135792   2014-01-21 21:58:03  ve10
   8   M  135792   2014-01-21 21:58:03  ve5
   9   M  135792   2014-01-21 21:58:03  ve4
  10   M  135792   2014-01-21 21:58:03  ve3

And the cluster status seems to be OK:

[B]root[/B][B]@[/B][B]ve10 [/B][B]~ [/B][B]# [/B]pvecm status
Version: 6.2.0
Config Version: 16
Cluster Name: mycluster
Cluster Id: 54391
Cluster Member: Yes
Cluster Generation: 135796
Membership state: Cluster-Member
Nodes: 10

Node votes: 1

Node name: ve10
Node ID: 7
Multicast addresses: 239.192.212.76 
Node addresses: 192.168.20.10

But I see all nodes with the red icon in the web interface, and I get the "Device or resource busy" when I try to make some changes to the virtual machines.

I tried to restart pvedaemon and cman but without solving the problem:

[B]root[/B][B]@[/B][B]ve10 [/B][B]~ [/B][B]# [/B]/etc/init.d/cman restart
Stopping cluster:

Could you help me please?
Thank you very much!

You need to restart the following services after restarting cman:

# service pve-cluster restart
# service pvedaemon restart
# service pveproxy restart
# service pvestatd restart
