Helllo,
I've reviewed some recent posts in this list and also searched Google for
info about autoscale and overlapping roots. In what I have found I do not
see anything that I can understand regarding how to fix the issue -
probably because I don't deal with Crush on a regular basis.
My particulars: I have an up-to-date Reef cluster in production with some
EC pools and some replicated pools. My error messages look like:
pool default.rgw.buckets.data won't scale due to overlapping roots: {-1, -2}
>From what I read and looking at 'ceph osd crush rule dump', it looks like
the 8 replicated pools have
"op": "take",
"item": -1,
"item_name": "default"
whereas the 2 EC pools have
"op": "take",
"item": -2,
"item_name": "default~hdd"
To be sure, all of my OSDs are identical - HDD with SSD WAL/DB.
Please advise on how to fix this.
Thanks.
-Dave
