Peter, We're seeing the same issues as you are. We have 2 new hosts Intel(R) Xeon(R) Gold 6248R CPU @ 3.00GHz w/ 48 cores, 384GB RAM, and 60x 10TB SED drives and we have tried both 15.2.13 and 16.2.4 Cephadm does NOT properly deploy and activate OSDs on Ubuntu 20.04.2 with Docker. Seems to be a bug in Cephadm and a product regression, as we have 4 near identical nodes on Centos running Nautilus (240 x 10TB SED drives) and had no problems. FWIW we had no luck yet with one-by-one OSD daemon additions through ceph orch either. We also reproduced the issue easily in a virtual lab using small virtual disks on a single ceph VM with 1 mon. We are now looking into whether we can get past this with a manual buildout. If you, or anyone, has hit the same stumbling block and gotten past it, I would really appreciate some guidance. Thanks, Marco On Thu, May 27, 2021 at 2:23 PM Peter Childs <pchilds(a)bcs.org> wrote:

You may be running into the same issue we ran into (make sure to read the first issue, there's a few mingled in there), for which we submitted a patch: https://tracker.ceph.com/issues/50526 https://github.com/alfredodeza/remoto/issues/62 If you're brave (YMMV, test first non-prod), we pushed an image with the issue we encountered fixed as per above here: https://hub.docker.com/repository/docker/ormandj/ceph/tags?page=1 . We 'upgraded' to this when we encountered the mgr hanging on us after updating ceph to v16 and experiencing this issue using: "ceph orch upgrade start --image docker.io/ormandj/ceph:v16.2.3-mgrfix". I've not tried to boostrap a new cluster with a custom image, and I don't know when 16.2.4 will be released with this change (hopefully) integrated as remoto accepted the patch upstream. I'm not sure if this is your exact issue, see the bug reports and see if you see the lock/the behavior matches, if so - then it may help you out. The only change in that image is that patch to remoto being overlaid on the default 16.2.3 image.

I've actually managed to get a little further with my problem. As I've said before these servers are slightly distorted in config. 63 drives and only 48g if memory. Once I create about 15-20 osds it continues to format the disks but won't actually create the containers or start any service. Worse than that on reboot the disks disappear, not stop working but not detected by Linux, which makes me think I'm hitting some kernel limit. At this point I'm going to cut my loses and give up and use the small slightly more powerful 30x drive systems I have (with 256g memory), maybe transplanting the larger disks if I need more capacity.

Does the image we built fix the problem for you? That's how we worked around it. Unfortunately, it even bites you with less OSDs if you have DB/WAL on other devices, we have 24 rotational drives/OSDs, but split DB/WAL onto multiple NVMEs. We're hoping the remoto fix (since it's merged upstream and pushed) will land in the next point release of 16.x (and it sounds like 15.x), since this is a blocking issue without using patched containers. I guess testing isn't done against clusters with these kinds of configurations, as we can replicate it on any of our dev/test clusters with this type of drive configuration. We weren't able to upgrade any clusters/deploy new hosts on any clusters, so it caused quite an issue until we figured out the problem and resolved it. If you want to build your own images, this is the simple Dockerfile we used to get beyond this issue: $ cat Dockerfile FROM docker.io/ceph/ceph:v16.2.3 COPY process.py /lib/python3.6/site-packages/remoto/process.py The process.py is the patched version we submitted here: https://github.com/alfredodeza/remoto/pull/63/commits/6f98078a1479de1f246f9… (merged upstream).

Peter and fellow Ceph users, I just wanted to update this forum on our interim findings so far, but first and foremost, a HUGE thank you to David Orman for all of his help. We're in the process of staging our testing on bare metal now, but I wanted to confirm that for us at least, the showstopper issue we were having trying to add more than 25 OSDs is no longer reproducible in our virtual ceph lab. We are using Ubuntu 20.04.2 and bootstrapping off a modified image that David Orman created and shared which includes the "remoto" fix. We'll be creating our own image for production deployment, but expect to finally be able to make some progress. David: Thanks again, as it's not often that people will extend themselves to create a patched image for someone else's use. In case anyone else is hit with this same problem, and until we can get a fixed release available, when deploying your new cluster with cephadm pay special attention to the bootstrap syntax. The bootstrap command itself accepts a "--image "path-to-image" but the bootstrap command does not. As such order is important, and you will find that you need to structure as: cephadm --image "path-to-image" bootstrap --mon-ip AAA.BBB.CCC.DDD <and append any other flags you wish> Once we have verified on bare metal I'll update all again.
