[Gluster-users] "Incorrect brick" errors

[Toby Corkindale]

I never did manage to figure this out.
All attempts to replace-brick failed inexplicably; we could add-brick 
but then still not remove-brick the old one, and the new bricks didn't 
seem to be functioning properly anyway.

Eventually we just sucked it up and caused a couple of hours of downtime 
across all production servers while we brought up a whole new gluster 
cluster and moved everything to it.

That's been the final straw for us though -- we're going to ditch 
Gluster across the company as soon as possible. It's too risky to keep 
using it.
It's been unreliable and unpredictable, and if anything version 3.3 has 
been worse than 3.2 for bugs. (And I have no faith at all that 3.4 is an 
improvement)
