Note Pantheon is updated now and you don't have to use the Jenkins build links. Hi John, Based on https://bugzilla.redhat.com/show_bug.cgi?id=1541415#c50 and further comments, it seems that support for this feature has been provided for containerized scenario also. Can you please add the new section to container guide also ? Regards, Vasishta Shatsry QE, Ceph Hi John, Thanks for the changes. Here are another other small changes required. 1) Ref - https://bugzilla.redhat.com/show_bug.cgi?id=1652475#c6 In doc where we mention about ceph-volume lvm batch - We can mention about block_db_size which would allow users to reserve specific amount of memory for blockdb so that adding OSDs can be an option preventing maximum allocation for initial OSDs Refer - https://github.com/ceph/ceph-ansible/blob/master/group_vars/all.yml.sample#L365 2) ----- Optional, I think it would be better if we add ---- Either we can change the name of the section to "configuring osds ansible settings" on all NVMe storage or add a sentence after step 3 asking users to go back to previous section (Step 6) before which user might have come to this section. Regards, Vasishta Shastry QE, Ceph Hi John, I'm sorry (In reply to Vasishta from comment #12) > Hi John, > > Thanks for the changes. > > Here are another other small changes required. > > 1) Ref - https://bugzilla.redhat.com/show_bug.cgi?id=1652475#c6 > > In doc where we mention about ceph-volume lvm batch - We can mention about > block_db_size which would allow users to reserve specific amount of memory > for blockdb so that adding OSDs can be an option preventing maximum > allocation for initial OSDs > > Refer - > https://github.com/ceph/ceph-ansible/blob/master/group_vars/all.yml. > sample#L365 > Above point doesn't apply here where there are only NVMes. But applies when there are mixture of NVMe and HDDs. Please ignore and consider point 2 only. Regards, Vasishta Shastry QE, Ceph Hi John, Thanks for the update. Moving to VERIFIED state.
