Hi,
Following on this, are there any restriction or issues with setting a new rule on a pool, except for the resulting backfilling?
I can't see anything specific about it in the documentation, just the command ceph osd pool set {pool-name} crush_rule with the description
crush_rule
Description
The rule to use for mapping object placement in the cluster.
Type
String
Does it work equally (well) for replicated and ec, changing m/k values, etc?
Many thanks!

Just create new one with your failure domain and switch the pool rule. Then delete old rule
