Hi all,

our Ceph cluster is distributed across two datacenter. Due do network
maintenance the link between the two datacenter will be down for ca. 8
- 10 seconds. In this time the public network of Ceph between the two
DCs will also be down.

What can we do of best handling this scenario to have minimal or no
impact on Ceph?

We plan to set "noout", "nobackfill", "norebalance", "noscrub",
"nodeep",  "scrub" are there any other suggestions?
