PowerProtect Data Manager arama düğümünde bellek olmaması nedeniyle vm-file-extractor işlemi çalıştırılamıyor. Boş belleğin minimum gereksinimi 800 MB'dir. vm-file-extractor ın çalıştırılamaması salt okunur bitin düzgün ayarlanmamasına neden oldu. Bu nedenle, "VSS sessize alma işlemi salt okunur olarak ayarlandıktan sonra diskler okuma/yazma moduna sıfırlanamıyor" hatasına yol açıyor.

1. SSH kullanarak PowerProtect Data Manager cihazında oturum açın, kök kullanıcıya geçin ve PowerProtect Data Manager arama düğümünün parolasını almak için aşağıdaki komutları çalıştırın.

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

2. 1. adımda edindiğiniz kimlik bilgilerini kullanarak her bir arama düğümünde oturum açın.
3. Arama düğümünün bellek kullanımını kontrol etmek için aşağıdaki komutu çalıştırın.

free -m

4. Boş bellek gerçekten 800 MB'tan azsa arama düğümüne daha fazla bellek ekleyin veya ayrılan belleği boşaltmak için PowerProtect Data Manager boştayken arama düğümünü yeniden başlatın.
5. VM geri yüklemesini yeniden çalıştırın.
