Re: [ceph-users] Fixing a crushmap
Here was the process I went through. 1) I created an EC pool which created ruleset 1 2) I edited the crushmap to approximately its current form 3) I discovered my previous EC pool wasn't doing what I meant for it to do, so I deleted it. 4) I created a new EC pool with the parameters I wanted and told it to use ruleset 3 On Fri, Feb 20, 2015 at 10:55 AM, Luis Periquito periqu...@gmail.com wrote: The process of creating an erasure coded pool and a replicated one is slightly different.

Re: [ceph-users] Fixing a crushmap
Oh, and I don't yet have any important data here, so I'm not worried about losing anything at this point. I just need to get my cluster happy again so I can play with it some more.

The process of creating an erasure coded pool and a replicated one is slightly different. You can use Sebastian's guide to create/manage the osd tree, but you should follow this guide http://ceph.com/docs/giant/dev/erasure-coded-pool/ to create the EC pool.
