Impatto

La stabilità dei servizi ScaleIO in esecuzione sull host può essere compromessa.

Cause

Problema causato da un problema software con il driver della scheda di rete integrato nel kernel Linux

Resolution

Disabilitare le funzioni di offload TSO e GSO:

# ethtool -K ethX tso off gso off

 Per una correzione permanente, aggiornare il kernel a kernel-3.10.0-514.17.1.el7 o versioni successive (vedere: i40e: Problema del driver TX rilevato, reimpostazione PF emessa - Red Hat Customer Portal
