SnapRAID - Disks - Add a parity disk to an existing array

Add the proper “N-parity” option in the configuration file, and then run the “sync” command, using the “-F, –force-full” option:

snapraid -F sync

NOTE: The “-F” option tells SnapRAID to recompute the full parity.

During the process, the existing data is still protected because the existing parity is not modified.
