Multi-stream read operation from a deduplicated storage policy copy that has a Silo copy configured might fail
Job fails with the following error:
Error Code: [62:2339]
Description: Failed to Copy or verify Chunk [ ] in media [CV_MAGNETIC], Storage Policy [ ], Copy [ ], Host [ ], Path [ ], File Number [ ], Backup Jobs [ ]. Error with SI Volume DB. Make sure SQLite DB is not corrupted.
When a Silo copy is created, a SIVolumeDB database file is created on the mount path of the source copy's disk library. This database file is used for read operations to determine if the data is available on the disk library or has been moved to the tape library where it would need to be retrieved. This read operations can include Auxiliary Copy operation, data verification, DDB reconstruction, restores. If a large number of streams from one of these operations tries to access the database at the same time, it can cause lock timeout errors with the SIVolumeDB.
To resolve this issue:
Configure this setting on each MediaAgent that shares the mount path.
