[Gluster-users] While running a rebalance, what does the metric "layout" represent

[Burnash, James]

Sure, Joe  - I will get that to you. I do have dstat on the machines.

What I'm really interested in, however is what the actual number following "layout" represents? Inodes? Blocks? Files? Any idea?

In this case, there are two HP storage servers running external enclosures with a 1.5Gb link, filled with 70 SATA 2TB drives configured as RAID 50 and running over a active / passive bonded 10Gb network connection. All servers are local to the same switches - single hop between them.

Each storage server hosts 10 bricks of 12TB each.

Does that help? It would be exceptionally cool if there was a calculator to help with all this ... I could do the math if I had to , but it's not ... my first language :-)

Thanks!

James Burnash, Unix Engineering

Rebalancing is going to be pretty intensive.  What sort of network do
you have between bricks, what sort of bricks, and how many?

Can you get dstat output on a few of the machines? (dstat is here:
