Recovering from system drive failure and possible storage volume failure
If the system drive on a virtual Storage Node has failed, the Storage Node is not available to the StorageGRID Webscale system. You must complete a specific set of tasks to recover from a system drive failure.
About this task
This recovery procedure applies to virtual Storage Nodes only.
Remounting and reformatting storage volumes ("Manual Steps")
You must manually run two scripts to remount preserved storage volumes and reformat failed storage volumes. The first script remounts volumes that are properly formatted as StorageGRID Webscale storage volumes. The second script reformats any unmounted volumes, and rebuilds the Cassandra database on the Storage Node as required.
Restoring object data to a storage volume
After recovering a storage volume on a Storage Node where the system drive also failed and was recovered, you can restore object data to the recovered storage volume from other Storage Nodes and Archive Nodes.
Checking the storage state after recovering a Storage Node system drive
After recovering the system drive for a Storage Node, you must verify that the desired state of the Storage Node is set to online and ensure that the state will be online by default whenever the Storage Node server is restarted.
