hi anthony ... many thanks for that.
i did not understood, why the docu missed that part ... anyway
i checked the login and the mail adress ceph@xxxxxxxxx should be right

mode is the right way?
do you have any other ideas about disaster recovery?

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

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:
https://docs.ceph.com/en/latest/rados/operations/stretch-mode/
with the crushmap i ended in an error:
in rule 'stretch_rule' item 'dc1' not defined (dc1,2,3 is like
site1,2,3 in the docu).
my osd tree looks like
pve-test02-01:~# ceph osd tree
ID CLASS WEIGHT TYPE NAME STATUS REWEIGHT PRI-AFF
-1 3.80951 root default
-15 0.06349 host pve-test01-01
0 ssd 0.06349 osd.0 up 1.00000 1.00000
-19 0.06349 host pve-test01-02
1 ssd 0.06349 osd.1 up 1.00000 1.00000
-17 0.06349 host pve-test01-03
2 ssd 0.06349 osd.2 up 1.00000 1.00000
...
i think there is something missing.
should i need adding the buckets manually?
...
for disaster failover, any ideas are welcome.
man thanks for help and kind regards,
ronny
