Ceph

work in progress

Here is the current, mandatory, sequence to create an erasure coded pool:

• ./ceph osd crush rule create-erasure ecruleset
• ./ceph osd pool create ecpool 12 12 erasure crush_ruleset=ecruleset

It is proposed to allow for

• ./ceph osd pool create ecpool 12 12 erasure

to be a shortcut to

• ./ceph osd crush rule create-erasure ecpool
• ./ceph osd pool create ecpool 12 12 erasure crush_ruleset=ecpool

i.e. implicitly create a ruleset named after pool, if it does not already exist.
