So, what will you do? RAID1? No raid?
How does gluster detect a failed disk with no raid? What I don't understand
is how gluster will detect a failure on a disk and the reply with data on
the other server.
With a raid controller, if controller detect a failure, will reply with KO
to the operating system, but with no raid? What will happens?
Is safer to use a 24 disks server with no raid and with 24 replicated and
distributed bricks (24 on one server and 24 on other server)?
