Hi,

Thanks for your answer.
On the other nodes there are no errors in this period.
In the Cisco log there are only link-down errors due to the restart of 'nodo1'. There is no error before. I attach the Cisco log during this period. We use bond between nodo1 and Cisco switch. The storage is connected to another port of the same switch and is shared between all the nodes.
Is it possible that there is some bug with NFS in ovirt?

Hello, Pablo.
It looks like nodo1 have lost connection with the storage (sanlock on nodo1 
can't renew leases), then nodo1 has been reset by the watchdog.
Are there any errors in logs on the other nodes at this period (15:02 - 15:03)?
Are there any errors (near 15:02:13) in cisco9000's log (except those which was 
after 15:03:36 - when nodo1 reboots)?
Do you use bond on nodo1 for storage connection?
