There are several tasks you can perform to help determine the source of Storage Node related problems.
More information
Object store (storage volume) failures
The underlying storage on a Storage Node is divided into object stores. These object stores are physical partitions that act as mount points for StorageGRID system’s storage. Object stores are also known as storage volumes.
Troubleshooting SMTT alarms
If a Total Events (SMTT) alarm appears on a node, it could mean that platform services messages cannot be delivered or that a Cassandra out-of-memory error has occurred.
Lost and missing object data
Objects can be retrieved for several reasons, including read requests from a client application, background verifications of replicated object data, ILM re-evaluations, and the restoration of object data during the recovery of a Storage Node.
