raidz1 configuration

[phier]

Hello,
is it possible to mix 3x8tb drive and 1x16tb to create one raidz1 with total size 24TB, and use spare 8tb for less critical data (like backups from laptops for example...)?

thanks!

Hello,
Maybe is possible from command line but I don't think is a good thing to do.
Usually the entire disk is part of a pool.
Best Regards,

At the GUI the 16TB drive will be treated as an 8TB drive = so yes RAIDZ1 4 * 8TB wide will work.
Whilst it is then technically possible to use the remaining 8TB as a seperate Pool on its own this will require:

1. Command Line configuration
2. Acknowledgment that here be dragons and that you are way out on a limb here
3. Use of this pool will impact use and performance of the main Z1 Pool
4. This 8TB of data has no protection

Art of Server has a series called "forbidden art of ZFS" (I think) on Youtube where he demonstrates a somewhat more complex version of this scenario. So technicaly yes - advised, no
