Hi Sage,
since this problem is tunables-related, do we need to expect same behavior or

Hi Sage, Andrija List
I have seen the tuneables issue on our cluster when I upgraded to firefly.
I ended up going back
Hi Sage,
since this problem is tunables-related, do we need to expect same behavior
or not when we do regular data rebalancing caused by adding new/removing
OSD? I guess not, but would like your confirmation.
I'm already on optimal tunables, but I'm afraid to test this by i.e.
shuting down 1

after seting ceph upgrade (0.72.2 to 0.80.3) I have issued ceph osd crush

If there is somewhere else where you think a warning flag would be useful,
let me know!
Generally speaking, we want to be able to cope with

Hi,
which values are all changed with ceph osd crush tunables optimal?
Is it perhaps possible to change some parameter the weekends before the
upgrade is running, to have more time?
(depends if the parameter are available in 0.72...).
The warning told, it's can take days... we have an cluster

There are some brand new crush tunables that fix.. I don't even remember
off hand.
In general, you probably want to stay away from 'optimal' unless this is a
fresh cluster and all
Udo, I had all VMs completely unoperational - so don't set optimal for
