Re: Erasure Profile Update

The erasure profile cannot be changed on a pool.  If you want to change the profile to be 5+2 instead of 3+2, then you need to create a new pool with the new profile and migrate your data to it.

Subject: [ceph-users] Erasure Profile Update

Hi,

I'm looking for the way to do erasure profile update regarding to nodes addition. Let's say on the first I have 5 OSD nodes with 3+2 erasure profile so all chunks, including the code chunks, will be spread on every OSD nodes. In the future, let's say I add 2 OSD nodes and I wan to have 5+2 erasure profile to have all chunks be spread on every OSD nodes too. How can I do that without interrupting Ceph service to clients? 

Best regards,
