That, actually, is the norm. It is NOT normal to partition a raid array.
In my understanding you are contradicting yourself here.
Is there a difference between
"create filesystem on the entire device"
and
"partition a raid array"
?
Yes, they are not the same.
"create filesystem on the entire device"
you create a filesystem on the raw device, like with "mkfs.xfs /dev/sdc"
or "mkfs.xfs /dev/md0"
a lot of people do this with raid devices, but it is rarely if ever done
directly on HDD. afaik most installers will do this with raid devices,
but never with normal HDD
"partition a raid array"
this means creating a partition table on the raid array, i.e. "fdisk
/dev/md0" and creating partitions on it.
Here opinions differ. I am someone who often does this, and has
production machines with partitioned raid :)
wols thinks it is not to be done.
