Hello,
In my Sanity check thread I postulated yesterday that to get the same
redundancy and resilience for disk failures (excluding other factors) as
my proposed setup (2 nodes, 2x 11 3TB HDs RAID6 per node, 2

Yeah, I saw erasure encoding mentioned a little while ago, but that's
likely not to be around by the time I'm going to deploy things.
Nevermind that super bleeding edge isn't my style when it comes to
production systems. ^o^
And at something like 600 disks, that would still have to be a

Three things come to my mind when looking at your setup/results:
1)The number of pg's. According to the documentation it should be:
(number of OSD * 100 ) / number of replicas.
Maybe playing with the number a bit would yield better results.
2) Although I am NOT using SSD's as journals, I am

So is it recommended to adjust the rebalance timeout to align with the time to
