Cause

Nie można uruchomić procesu vm-file-extractor z powodu braku pamięci w węźle wyszukiwania PowerProtect Data Manager. Minimalna wymagana ilość wolnej pamięci to 800 MB. Niepowodzenie uruchomienia vm-file-extractor spowodowało, że bit tylko do odczytu nie został prawidłowo ustawiony. Prowadzi to do błędu "Nie można zresetować dysków do trybu odczytu/zapisu po ustawieniu operacji spoczynku VSS na tylko do odczytu".

Resolution

1. Zaloguj się do urządzenia PowerProtect Data Manager za pomocą SSH, przełącz się na użytkownika root i uruchom poniższe polecenia, aby uzyskać hasło do węzła wyszukiwania PowerProtect Data Manager.

source /opt/emc/vmdirect/unit/vmdirect.env && /opt/emc/vmdirect/bin/infranodemgmt get -secret -node_type SearchNode

2. Zaloguj się do każdego węzła wyszukiwania przy użyciu poświadczeń uzyskanych w kroku 1.
3. Uruchom poniższe polecenie, aby sprawdzić użycie pamięci przez węzeł wyszukiwania.

free -m

4. Jeśli ilość wolnej pamięci jest mniejsza niż 800 MB, dodaj więcej pamięci do węzła wyszukiwania lub uruchom ponownie węzeł wyszukiwania, gdy PowerProtect Data Manager jest bezczynny, aby zwolnić przydzieloną pamięć.
5. Uruchom ponownie przywracanie maszyny wirtualnej.
