NOTE: Using some of the maintenance command options could result in the deletion of data. Carefully observe the warnings (for example, running the scan without running the repair). If you have questions, do not perform these DR Series system CLI command options without first contacting Technical Support.

NOTE: If you specify a command without supplying the expected value or option, you are prompted to provide the correct value or option.

maintenance --filesystem [--start_scan [verify_data | verify_rda_metadata | verify_metadata] [--storage_group <name>]

maintenance --filesystem [--start_scan [verify_data || verify_metadata] [--storage_group <name>]

Description

Starts filesystem checker to check for consistency issues in storage groups.

NOTE: Argument verify_data validates data with pre-built checksum. Argument verify_rda_metadata scans only OST and RDA containers. Argument verify_metadata scans the namespace for all containers.

NOTE: Using this command places the files system into a read-only mode and pauses all active replications. When the DR Series system enters Maintenance mode, an alert is sent that indicates this operational change.

Syntax

maintenance --filesystem --start_scan verify_data --storage_group SGTest1

Result

This operation will make the filesystem read-only and pause all active replications.
"verify_data" option will check for data consistency issues in the filesystem. This might take long time to complete.

maintenance --filesystem --scan_restart

"Operation not supported as system is not in maintenance mode.
To be able to restart scan, filesystem check must be running or waiting".
