El proceso vm-file-extractor no se puede ejecutar debido a la falta de memoria en el nodo de búsqueda de PowerProtect Data Manager. El requisito mínimo de memoria libre es de 800 MB. La falla de la ejecución de vm-file-extractor causó que el bit de solo lectura no se configurara correctamente. Por lo tanto, se genera el error "No se pueden restablecer los discos al modo de lectura/escritura después de que la operación de reposo de VSS los configure en solo lectura".

1. Inicie sesión en el dispositivo PowerProtect Data Manager mediante SSH, cambie al usuario raíz y ejecute los siguientes comandos para obtener la contraseña del nodo de búsqueda de PowerProtect Data Manager.

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

2. Inicie sesión en cada nodo de búsqueda con las credenciales obtenidas en el paso 1.
3. Ejecute el siguiente comando para comprobar el uso de memoria del nodo de búsqueda.

free -m

4. Si la memoria libre es realmente menor que 800 MB, agregue más memoria al nodo de búsqueda o reinicie el nodo de búsqueda cuando PowerProtect Data Manager esté inactivo para liberar la memoria asignada.
5. Vuelva a ejecutar la restauración de la máquina virtual.
