now i have 2 questions.
whats the right way to add another pool?

the exsisting pools were automaticly set to 4/2 after "ce

Yes, you will need to create datacenter buckets and move your host

hi there, need some help please.
we are planning to replace our rbd-mirror setup and go to stretch mode.
the goal is, to have the cluster in 2 fire compartment server rooms.
start was a default proxmox/ceph setup.
now, i followed the howto from:

i would like to know, if there are some news of your setup.
do you have replication active running?
No, there was no change at CERN. I am switching jobs as well actually
so I won't have much news for you on CERN infra in the future. I know
a problems in your tests.
i think, there are not so many people, how are using ceph replication.
for me its hard to find the right way.
can a snapshot based ceph replication be crash consisten? i think no.
thanks für any help there ...

Hi Ronny
Yes according to my test we were not able to have a good replication
speed on a single image (I think it was 30Mb/s per image something like
that). So you have probably a few image that writ
help, load stays up.
now we went back to journal, but the pool size is growing again.
does anybody use rbd mirroring?
which type are you using? what would you prefer?
we are running against walls ... so any help is welcome.
