Valid nfsdclddb subcommands are:

Downgrade the database schema. Currently the schema can only to downgraded from version 4 to version 3.
Display the contents of the database. Prints the schema version and the values of the current and recovery epochs. If the -s|--summary option is not given, also prints the clients in the reboot epoch tables.


Options valid for all sub-commands

Show the help message and exit
Open the sqlite database located at dbpath instead of /var/lib/nfs/nfsdcld/main.sqlite. This is mainly for testing purposes.

Options specific to the downgrade-schema sub-command

The schema version to downgrade to. Currently the schema can only be downgraded to version 3.

Options specific to the print sub-command

Do not list the clients in the reboot epoch tables in the output.


The nfsdclddb command will not allow the fix-table-names or downgrade-schema subcommands to be used if nfsdcld(8) is running.
