we want to know if we can to upgrade to HDP 3.0 from HDP 2.6.4 ( regarding the disks aspect )
and we want to know if current disks configuration enable this upgrade
we have the following RAID configuration
1) Worker-> (OS) Raid1 + ( data disks ) Raid 5 2) Master -> (OS) Raid1 + ( data disks ) Raid10 3) Kafka-> (OS) Raid1 + ( data disk ) Raid10
about the kafka - each kafka has one data disk
about the workers ( data-node ) - each worker has 10 data disks
based on that configuration , can we upgrade to HDP 3.0 version ?
