Interesting. How do you set this "maintenance mode"? If you have a series of documented steps that you have to do and could provide as an example, that would be beneficial for my efforts. We are in the process of standing up both a dev-test environment consisting of 3 Ceph servers (strictly for testing purposes) and a new production environment consisting of 20+ Ceph servers. We are using Ubuntu 22.04. -- Michael ________________________________ From: Daniel Brown <daniel.h.brown@thermify.cloud> Sent: Wednesday, June 12, 2024 9:18 AM To: Anthony D'Atri <anthony.datri@xxxxxxxxx> Cc: Michael Worsham <mworsham@xxxxxxxxxxxxxxxxxx>; ceph-users@xxxxxxx <ceph-users@xxxxxxx> Subject: Re: Patching Ceph cluster This is an external email. Please take care when clicking links or opening attachments. When in doubt, check with the Help Desk or Security. There’s also a Maintenance mode that you can set for each server, as you’re doing updates, so that the cluster doesn’t try to move data from affected OSD’s, while the server being updated is offline or down. I’ve worked some on automating this with Ansible, but have found my process (and/or my cluster) still requires some manual intervention while it’s running to get things done cleanly. > On Jun 12, 2024, at 8:49 AM, Anthony D'Atri <anthony.datri@xxxxxxxxx> wrote: > > Do you mean patching the OS? > > If so, easy -- one node at a time, then after it comes back up, wait until all PGs are active+clean and the mon quorum is complete before proceeding. > > > >> On Jun 12, 2024, at 07:56, Michael Worsham <mworsham@xxxxxxxxxxxxxxxxxx> wrote: >> >> What is the proper way to patch a Ceph cluster and reboot the servers in said cluster if a reboot is necessary for said updates?
