There are several tasks you can follow 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 (also referred to as storage volumes) are physical partitions that act as mount points for StorageGRID Webscale system’s storage. Object stores are also known as storage volumes.
Troubleshooting SMTT Alarms
If a Total Events (SMTT) alarm appears on a Storage Node, it may be related to a failure that means that platform services messages cannot be delivered.
Lost and missing object data
Retrieval attempts are made 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.
Troubleshooting replication queues
As the ingest rate increased, the number of ingests pending and the number of ILM evaluations pending increased because the LDR and CMS services could not keep up with the increased ingest rate.
