January 24, 20251 yr Hello 👋,  I was wondering if it's possible in Unraid to change the  filesystem type so I can downgrade from Raidz3 to Raidz2 and 1 disk less.    The data settings is showing a non-editable dropdown box of my current configuration.  In theory I could just remove 1 disk (maximum failing disks in Raidz3 is 3) and ignore the OS complaining, but I don't know if that's the best approach here.  The data size would be the same as you can see in Raidz calculators so from my naive point of view there shouldn't be an issue:  I couldn't find a similar topic, so I created this topic. Thank you!
