Same here… I am using Dell R710s with 8 disks,  2 x 1TB in RAID 0 and then 6 virtual disks, one per physical disks.  I think you have to do it that way for the dell perc controller to present the disk to the OS but I haven’t actually tried not doing that so not sure.. anyway this works.

This has been very informative. 

James has only 3 nodes, but I have 5…  I have another posting about what happens when I added the two additional nodes as all the disks seem to be locked and multipath and I can’t create bricks on them.

But, once I get pas that problem, if I have 5 nodes, and I am going to create replica datasttores with 3 disks, do I just 3 nodes for each datastore?  Is there any best practice for creating datastores on any 3 nodes…

Perhaps an example:

Datastore 1 -  Node1, Node2, Node3 /dev/sdb

Datastore 2 – Node2, Node3 /dev/sdc Node4 /dev/sdb

Datastore 3 -  Node3, /dev/sdd, Node4 /dev/sdc Node5 /dev/sda

Does that make sense?  Or is there a better way?

Thanks to everyone for helping me on this, much appreciated.

Hello,

In my case I'm referring to hosts with internal disks. 

Example of my hardware config:

host0:

2x250GB SSDs in RAID 1 mirror for OS/boot disk

2x2TB SSDs in JBOD (passthrough) represented as separate disks in the OS ex. /dev/sda and /dev/sdb

host1 and host2 have identical configurations.

When you say "JBOD", are these hosts with xx number of disks or hosts with a physically attached JBOD?
