Subject: [CentOS] Software RAID complete drives or individual partitions

If you configure an entire drive as a raid device, you'd have a device
name like /dev/mdp0, which you'd then partition. I think what

RAID5 performance can be abysmal, because of the parity calculations
and the fact that each write to the array requires that all drives be
read and written.

Large drives often have 4k sectors - don't you want a 1M offset to
make sure the partition start is aligned?
256K is a multiple of 4K. sure, you could use 2048s instead if you
wanted 1M boundaries, its all good.

indeed. the primary justification for the R in RAID, Redundant, is
high availability. having the OS on a non-raid volume completely
violates this.RAID is most definitely NOT a substitute for
testing with it to possible use it for some of the clients
that the business I work for do work for for basic file server services
