Installing Ceph 5 storage using cephadm

[@hamidsafe438]

Am in debt to your insightful magnificent video. Great help to me and respect from Iran; just a note that if you guys are around countries like mine give it time as the setup preparation and pulling images not entirely reflected here for the rest of the nodes :)😍

Excited to see the rados gateway setup!

I hoped it would be out by now, but I'm tied up with a few other things that take precedence. I'll get to finishing the video as quickly as I can.

[@subhobroto]

@@OCPdude No rush. Thank you for doing these!

[@OCPdude]

Just finished.. going to edit and post today!

[@subhobroto]

@@OCPdude can't wait. Have you had a chance to look into seaweedfs?

[@OCPdude]

@@subhobroto I have not, it looks interesting though.

[@hongenyang7650]

thanks 😄 it`s easy to learn ceph

[@subhobroto]

Check out next video in the series about Configuring Ceph 5 for Object Storage (RGW/S3) kzbin.info/www/bejne/op6plaOCntWUeKM Great series!

Great video, my question is, can I use it with okd to do dynamic storage?

[@OCPdude]

You can use Ceph with OKD, no problem.

[@damianborgi8300]

@@OCPdude Do I need to install any driver for that ?

[@damianborgi8300]

The thing is that I need to create a dynamic storage with elasticsearch and Kibana in my OKD cluster@@OCPdude

[@OCPdude]

@@damianborgi8300 you’ll likely want to leverage the csi drivers. rook.io/docs/rook/v1.12/Getting-Started/intro/ unfortunately (or fortunately) I’m on holiday and unable to find a better link for you. Hopefully with research this will prove helpful.

Trying to add an OSD to the cluster. One host is running solely linux, where as the other host is running a Virtual Machine. I have two monitors, one manager, and no filesystem. Ive tried several different ways but not luck (dashboard, manual,etc...). when runnign ceph orch daemon add osd, cephAdmin:/dev/sdb I get a huge error log, but the main premise is Error EEXIST: entity osd.0 exists but key does not match. I have tried ceph orch rm 0, and it says osd.0 does not exist. Any help would be appreciated.

[@OCPdude]

you can try to remove the key `ceph auth del osd.0` and then `ceph osd rm osd.0`. good luck

[@owenhill8462]

Found that the entity (osd.0) key was being stored somewhere and I saw it when i ran ceph auth ls. Now Im having more issues when i run ceph-osd -i 0 --mkfs --mkkey , which create a data store for the OSD. I get error like unable to locate keyring at /var/lib/ceph/osd/ceph-0, although the documentation says to ensure this folder is empty uponing running said command.

[@ismaellayth]

I got "mgr is not available" error after executing "cephadm bootstrap --mon-ip " command. What is the problem? :(

[@OCPdude]

Hard to figure that out, please have a look at the GitHub script and see the setup and install instructions help. Link in the description of this video.

[@PRAVIN1CA]

Thank You, Is this community ceph ?

[@OCPdude]

Yes it is.

This kind of video in 4k is a perfect bad idea. Everyone don't have a 4k screen, 100gb of internet connection and bionics eyes. And, finally, you use less that 50% of the screen surface. Please use a 16/9 or 16/10 ratio and a 1024x720 or 1920x1080 max for screen resolution (no video resolution), it is far more readable.

Hi, the viewing quality is adjustable from 140p, all the way up to 4k on KZbin; pick what works best for your viewing. As additional information, I have included the working script (link in description).😁
