Ben Corlett commented on KAFKA-6194:
------------------------------------
So the drives are EBS volumes. They are set up with lvm2 and a logical volume
formatted with ext4.
They have been set up this way and running for over a year.
I think we may end up downgrading back to 0.11.0.1 and the snapshot build of
1.0 (on broker 25) like we were at Tuesday. We'll need to bounce node 25 daily
to avoid it running out of heap, but at least the cluster will stay up.
