I hope that you are using a tool like foreman or spacewalk to deploy your dev & production environments as they allow you to "freeze" your repo content. Then you deploy all your servers with the content of these repositories (you may even use lifecycles to ease dev -> test -> prod) therefore they a

Hi! AFAIK the focus is on ceph-adm to replace ceph-ansible. Today it is still missing some important features but it is just a matter of time. I don't think that the devs will do twice the work, once for cephadm and once for ceph-ansible but if someone feels the need to keep it working and impleme

A containerized environment just makes troubleshooting more difficult, getting access and retrieving details on Ceph processes isn't as straightforward as with a non containerized infrastructure. I am still not convinced that containerizing everything brings any benefits except the collocation of s

2021-08-21 Thread Teoman Onay
You seem to focus only on the controller bandwith while you should also consider disk rpms. Most SATA drives runs at 7200rpm while SAS ones goes from 10k to 15k rpm which increases the number of iops. Sata 80 iops Sas 10k 120iops Sas 15k 180iops MBTF of SAS drives is also higher than SATA ones.

2021-11-04 Thread Teoman Onay
AFAIK dynamic resharding is not supported for multisite setups but you can reshard manually. Note that this is a very expensive process which requires you to: - disable the sync of the bucket you want to reshard. - Stops all the RGW (no more access to your Ceph cluster) - On a node of the master z
