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 _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
