Using the CLI to Enable Recovery with Writes

On occasion, the data that has been disrupted is part of the file system on the disk drives. When this is the case, it is useful to run the file system repair
tools for your operating system. This requires write access to the drives
.

WARNING: Use the RGRecoverWithWrites command only when necessary, and use with caution!

Put the RAID group into Basic or Extreme recovery mode with read and write access:

set rgrecoverwithwrites r5 basic

(or extreme)

Ready.

Run the appropriate file system repair utility prior to recovering data from the drives.
