When building zfs storage I've always kept to the following rule.
"The following ZFS pool configurations are optimal for modern 4K sector harddrives: RAID-Z 3, 5, 9, 17, 33 drives RAID-Z2: 4, 6, 10, 18, 34 drives RAID-Z3: 5, 7, 11, 19, 35 drives"
A recent project has caused me to question this as it would make my life easier if for example I could use 9 drives in a RAID-Z2 and not 10 due to chassis size.
I would be interested to hear your thoughts on this and if you consider this a hard and fast rule or quite the opposite just ignore it and configure your vdevs to suit your needs.
