Hello Everyone,
I have a newly re-created CEPH cluster and cannot create a new pool. I'm
using the following syntax, which has previously worked without issue in
the past:
ceph osd pool create rbd 1024 1024
The resulting error is:
"Error ERANGE: For better initial performance on pools expected to store
a large number of objects, consider supplying the expected_num_objects
parameter when creating the pool."
I have read the documentation which refers to "expected_num_objects",
but cannot figure out what the correct syntax should look like. I have
tried the following variation:
ceph osd pool create rbd 1024 1024 replicated
not_sure_what_to_define_for_the_crush_rule_set_name 0
But this results in an error stating that the crush rule set doesn't
exist. I have not had to define the crush rule set in previous testing.
If anyone can shed some light on this, I would be most appreciative.
Thank you,
Todd
