Any problem with partitioning a data disk to shrink the size of the disk?

1. offizieller Beitrag

    Hello


    I have a 8TB Western Digital external USB drive. I would like to shuck this and use this as a SATA data disk in my SnapRaid array (as I know it's a white label drive).


    Problem is that I would like to shrink it to 6TB so it matches my current WD blue label snapraid parity disk!


    Is that possible? i.e. To set it up in OMV first then partition it so it's 6TB?


    Thanks!


    Will.

    Why don't you do the opposite:


    Create the partition on CLI with only 6Tb and then add it to OMV?

    Or just leave it at 8tb. If you put too much on it, then it is possible you might fill your parity disk. Or better yet, use the 8tb as your parity disk.

    thank you Soma. Makes sense... I'll do that! :)

    That's what I was thinking but I don't use snapraid and am not super familiar with it.. but I thought one of the advantages snapraid was being able to hodge podge drives of different sizes together?

    Yep. You should just use the largest drive of your hodge podge for the parity drive. If none of the drives are completely full, it probably won't fill the parity drive though.

    Thanks for the suggestions. I just don't want to use my 8TB drive as the parity, as this is the nice WD white label drive (aka Red). So I want to use that as a data drive.


    Then my other 6TB drive is a blue label WD drive. I want to use this as parity since I would prefer that to fail (rather than a data drive).


    The rest of my WD data drives are WD Red drives.


    So my best option is to partition the 8TB down to 6TB in the CLI. I then have no chance of my parity drive getting filled!


    Phew! ;)

    Use the remaining 2TB for a second partition - you could use it for temporary storage, downloads, anything. It would just be a shame to waste it. 🙂

    thanks - good call. I will do that. :)
