Managing the cyclic redundancy checking (CRC) service
The cyclic redundancy checking (CRC) service is a data integrity check. Use the following procedures to manage the CRC service from the deduplication shell.
To view the status of the CRC service
- Open an SSH session to the server.
- Run one of the following commands:
To view the general status of the CRC service:
dedupe CRC state
To view the status of the fix mode on the CRC service:
dedupe CRC fixmode-state
To enable the CRC service or enable a different CRC mode
- Open an SSH session to the server.
- Run one of the following commands:
To enable the CRC service:
dedupe CRC enable
To enable fast checking, which begins the check from container 64 and does not sleep between checking containers:
dedupe CRC fast
When the fast CRC ends, CRC behavior reverts to the behavior before fast checking was invoked.
To enable fix mode, which runs the check and attempts to fix any inconsistent metadata:
dedupe CRC enable-fixmode
To disable the CRC service or fix mode
- Open an SSH session to the server.
- Run one of the following commands:
To disable the CRC service:
dedupe CRC disable
To disable fix mode:
dedupe CRC disable-fixmode
