Description of problem: [RFE] ceph-ansible: journal_size should have default value for example 5G. Version-Release number of selected component (if applicable): Red Hat Ceph Storage 2.0 We had some issues with customers. Where customer choose Journal size as 1024M and it created lot of issues for their deployment. As they had approx 300+ OSDs it was hard to reconfigure journal and it was like we need to redeploy the cluster. I have attached the customer case# 01518937 with this bug.
PR opened here: https://github.com/ceph/ceph-ansible/pull/902
PR merged, in the process of pushing this downstream.
This is not a blocker, let us document this var in the install guide. We can release it after 2.0
This is already documented in the install guide, so this one is more an enhancement requested by the consultants :)
It's not really deployment issues but more production stability and performance issues. I'll also highlight critical performance problems that will occur with a journal_size < 5GB.
LGTM thanks Bara!
This will ship concurrently with RHCS 2.1.
This looks like it is already in the stable-2.1 branch of ceph-ansible upstream.
