Hello!
There are 3 ways to deploy crimson.
1. cephadm. Vanilla images [1] from CI/CD should work though the `cpatch`
script (and thus `cstart.sh`) is problematic as we build these images with
different toolchain / options than the classical ones.
I believe this is the least frequented way at the moment and I would be
grateful for bug reports.
[1]: eg. https://shaman.ceph.com/builds/ceph/master/9ff904a467c040321318c9ea59e04402030f190d/crimson/301113/
2. Rook. Some folks already gave it a try and the crimson support went over
a few rounds of bug fixing. The sole departure from the classical OSD
is the need to inject the `examples/osd-env-overrride.yaml` [2]
before deploying
your OSDs. This won't be necessary when we start to ship crimson images
without ASan debug facility (production images).
[2]: https://github.com/rook/rook/pull/9647/files#diff-c7f1d89eb9467c9c152c0d03f14a385ee32c889010209ddc869636d3a96a319c
3. Manual builds. I think this is the most frequented way right now.
I also wanted to mention that if you do a manual build, you can deploy
multi-node test clusters with cbt in a similar way to deploying with
classic. I was planning to do that for quincy on our 10 node mako
cluster but got sidetracked by the allocator regression we are working
on now.

I think current main should have initial crimson support in cephadm.
Radek: is that right?

Dear community,
We are working trying to working on Crimson validation and want to test the large cluster deployment and performance for Ceph Crimson.
Just a quick questions, do we have a traditional method to run the multiple node deployments for Crimson-OSD instead of vstart.sh? Looking through the Cephadm/Ceph-ansible,I don't find one can support crimson-osd.
Thanks in advance!
