[one-users] opennebula monitoring fails

[Nicolas Diogo]

hello

i have a three node installation:
sunstone running on: on00

and also:
on01
on02


i find that running the command:

onehost list

shows my nodes to be listed with errors - err


giving the following entries on the /var/log/one/oned.log
/

    Fri Apr 12 02:10:16 2013 [InM][E]: Error monitoring host 11 :

i figure that it has to do with the command on host on00 (sunstone):

/*scp -r /var/lib/one/remotes/. on01:/var/tmp/one*/


i have run this command as user oneadmin, and it gave me no error.

after a that everything seems to work correctly. see log entries.

i would like to know what could have caused this behaviour on the systems?

the SSH keys and config is the same on all systems - no changes at all.
it is baffling to me.


thanks a lot.

Nicolas
