    I have a 24 drive array (3 parity, 21 data). My config file is gone due to my pirmary HD failure and my backups of the config file are too old as I've had 3 data drive replacements since I did the backup.

    Disks d3, d4 and d18 in my config file are incorrect and I wanted to know two things:

    1. Does it matter which order the disks are listed in if they are from the same snapraid setup?
    2. If it does matter - is there anything in the content file that will state what the order is?

    Thanks!

    1. Yes
    2. Yes

    -C, --gen-conf CONTENT_FILE
    Generates a dummy configuration file from an existing content file. The configuration file is written in the standard output, and it doesn't overwrite an existing one. This configuration file also contains the information needed to reconstruct the disk mount points, in case you lose the entire system.

    Example:
    snapraid -C snapraid.content

    I store the configuration file on each data disk and additionally on my system disk. I do not store on my parity disk. The additional storage used should not matter.

    Thanks for the info! It was dumb on my part to not have these files backed up away from the main drive. Oh well - lesson learned...!
