[Gluster-users] Is RAID necessary/recommended?

[Juan José Pavlik Salles]

It could be both necessary and recommended, depending on what you want to
achieve. I've gone through a few awkward moments because of not having RAID
in our distribute-replicated volume, but nothing you can't solve shutting
down the node and replacing the drive. RAID will give you transparency and
tolerance to drive failures and is even better if we talk about a good HW
RAID. What about RAID 5, is that possible?
