Ursache
Bug do PowerPath.
Durante um NDU do VPLEX, um director do VPLEX travou alguns segundos depois de voltar. Isso expôs um bug no PowerPath relacionado a aberturas de dispositivos, o que resulta na emissão de uma versão extra do PowerPath. Essa versão extra resulta em uma condição de uso após liberação e em pane no kernel do Linux.

Essa versão extra resulta em uma condição de uso após liberação e em pane no kernel do Linux.
Lösung
O PowerPath 6.1 HF1 e as versões futuras do PowerPath têm uma correção para esse bug.
Weitere Informationen
Tanto a Red Hat quanto a PowerPath Engineering conseguiram recriar a condição em laboratório, independentemente de um NDU do VPLEX. Além do rastro de volta do cliente, havia vários vestígios diferentes de pânico de volta que foram vistos.
Devido à natureza do uso-pós-livre, o pânico real pode ser visto em vários lugares.
