Hi,
I wanted to create a RAIDZ1 with 6 drives (5+1), but everything I read says it needs to be N+parity drive where N is in multiples of 2s. I could never really find an explanation as to why though since FreeNAS itself allows you to create a 5+1 RAIDZ1 configuration with no warnings of any sort.
I have a DELL server with 12 drives and was hoping to create a pool with 2 x (5+1 RAIDZ1). Just want to know if it's safe or if I really need to have an even number of data drives. I would hate to burn 2 additional disks on parity by having to run a 2 x (4+2 RAIDZ2) configuration.
Does anyone have a good explanation as to why 5+1 RAIDZ1 is not good/safe?
Thanks
