Hi Subhubroto Thank you for watching my videos. I've been asked to look into cephadm and a fully automatic install and upgrade process. In my mind it's an interesting feature that isn't there yet but might be really powerful in a couple of years. I'm also researching cluster solutions and their connection to Ceph. Best regards Daniel
Hi Daniel, again you video is super-helpful! 1 question BTW: can we use Objects Gateway on top of CephFS and therefore have access to the same files via both: CephFS and S3?
Hi Дневник No, CephFS and S3 use the same backend, Rados Object Storage. In this storage solution, you store multiple objects spread over different placement groups in a cluster of object storage devices. But the pools you set up for each solution are separate, and the two implementations are strictly different even though they use the same backend. I hope this helps. Thank you for watching my videos. Best regards Daniel
hi i try my best in understanding this whole conecpt, but i think a lot of things have changed since the tutorial and some things just dont work anymore. I have currently my master and 2 nodes but get multiple errors with the commands. Perhaps you could start over this project with the aim to create a Bucket, would be a huge help cause im really lost with the documentation from ceph themselfs
Hi. I might to a from Zero to bucket sometime. But I would suggest for you to watch the full series on how to setup Ceph. Maybe there is a step you've missed or a concept you have not grasped yet. I remember when I started with Ceph there was a lot of small details you needed to figure out but when you grasp a couple the rest fall into place. Thank you for watching my videos. Best regards Daniel
Thanks for the video, I have an openstack swift object storage server running S3 middleware. Can this RADOS GW be added to this type of configuration ? do you have any video regarding Ceph/SWIFT ??
Hi Currently I don't have any videos about Openstack Swift. Maybe I spin up a cluster in the future and look into it. But when it comes to the RADOS gateway they are working on adding more back-ends so it should be possible to use it for a wide variety of things so I would look a the documentation and see if they have added Swift yet. Best regards Daniel
Hello i've been successfully install rados gateway with cephadm shell with command: ceph orch apply rgw default us-east-1 --placement="1 server1" after that I enable ceph dashboard with "ceph dashboard set-rgw-credentials", but every time I use ceph dashboard object gateway menu, it appear error info "The Object Gateway Service is not configured Error connecting to Object Gateway", do you have any suggestion? FYI I use Ceph Pacific version after upgrade it from Octopus
ha ha ha, its solving it self after I upgrade my ceph cluster from pacific to quincy than recreate the Object gateway on quincy, I think it's bug from pacific
Hi XYZ Thank you for watching my videos. Yes, you could configure haproxy and a service like heartbeat to share an IP over servers. So when n1 is up it will have the ip. If it disappears n2 will configure their interface to use the ip. You need more than one net so you can have backbone traffic on a separate interface. But it's doable. I hope this helps. Best regards Daniel
Very helpful, I am able to enable rados gateway on red hat ceph object storage. I was stuck in red hat ceph documentation. Thanks daniel. I have one more problem, i have cluster in public network of 1GB, but i want to move that setup in private 10GB network., Installed new adapters and having both IPs now. How it can be done ? Thanks again.
Hi Bharat Great question. We are facing similar issues at work. And I'm looking at a solution and will test it out. Maybe even create a video on the topic. The most hard / compilated issue that you will face is changing the IP of your monitors. This is not recommended and can be really complicated. But I found a guide that might give you more insight into the process. docs.ceph.com/en/latest/rados/operations/add-or-rm-mons/#changing-a-monitor-s-ip-address I hope this helps. Thank you for watching my videos. Best regards Daniel
I am encountering this error in the Object Gateway tab. 500 - Internal Server Error The server encountered an unexpected condition which prevented it from fulfilling the request. how can i solve it?
Hi Örner The best way to proceed with an "Internal Server Error" to contact you server administrator or in the case of your own server look at the logs for the Object Gateway. I hope this helps. Thank you for watching my videos. Best regards Daniel
Hi Sam Thank you for watching my videos. That is some video topic I could cover in some depth as I've solved a couple of these issues. (Last on New Year's Eve) I'm not sure what video will be the first it depends on research time and my health. (No voice today) Best regards Daniel
I guess this is good for setup rados gateway for manual type of ceph cluster. However cluster deployed and managed by cephadm? How to use cephadm to setup rados gateway?
Hi Vincent. Well, it should be pretty straightforward. You could use the GUI for most of it. Choosing the number of gateway interfaces you need and the system will automagically push out those services on one or more of your hosts. Then after that, it should create the pools for you, and you can create users and buckets. You have less control over where it actually ends up, and you might be required to fish for the URL to use for your connection, but it should be doable. Maybe I'll look into this in the future. If you want, you could do it manually, even on a system deployed with CephAdm, as I explained in the video, but as you have chosen the managed way, you probably want the automatic answer. I hope this helps. Thank you for watching my videos. Best regards Daniel
Hi, I think is ceph is a unix child, where you have to play with a lot of parameters to have the solution you need; the problem with ceph is that the documentation is confusing and here where the Daniel video comes to play.
Hi Daniel, thank you very much for your video; however I'm pretty sure that with the release of quincy something changed in setup; after starting radosgw on the first monitor (called mon1 in my case) the daemon crashed with that into the logs: 2023-03-20T16:04:36.414+0100 0 ceph version 17.2.5 (98318ae89f1a893a6ded3a640405cdbb33e08757) quincy (stable), process radosgw, pid 2134 2023-03-20T16:04:36.414+0100 0 framework: beast 2023-03-20T16:04:36.414+0100 0 framework conf key: endpoint, val: mon1.anonicloud.intra:8080 2023-03-20T16:04:36.414+0100 1 radosgw_Main not setting numa affinity 2023-03-20T16:04:36.418+0100 1 rgw_d3n: rgw_d3n_l1_local_datacache_enabled=0 2023-03-20T16:04:36.418+0100 1 D3N datacache enabled: 0 2023-03-20T16:04:37.730+0100 0 rgw main: rgw_init_ioctx ERROR: librados::Rados::pool_create returned (34) Numerical result out of range (this can be due to a pool or placement group misconfiguration, e.g. pg_num < pgp_num or mon_max_pg_per_osd exceeded) 2023-03-20T16:04:37.730+0100 0 rgw main: failed reading realm info: ret -34 (34) Numerical result out of range 2023-03-20T16:04:37.730+0100 0 rgw main: ERROR: failed to start notify service ((34) Numerical result out of range 2023-03-20T16:04:37.730+0100 0 rgw main: ERROR: failed to init services (ret=(34) Numerical result out of range) 2023-03-20T16:04:37.730+0100 -1 Couldn't init storage provider (RADOS) So it seems that is not able to create the default pools you get after starting radosgw the first time; I started with a clean cluster. Any idea?
HI Francesco I've not experienced this issue before. There might be some mismatch between the pool setup between versions. Maybe you need to set the flag allowing overwrite on the pool again, or perhaps you need to ensure that your minimum Bluestore version is Quincy. Other options could be to change the mon_max_pg_per_osd value, but I think the original value should be sufficient. Does the pool have essential data stored on it? Otherwise, you could test recreating it. Sadly Ḯ've seen differences between the implementation of S3 API from Pacific to Quincy, and I know that they are working on making even larger changes in the new Reef version. This might not be the best response, but I don't have any better input, I'm afraid. Thank you for watching my videos. Best regards Daniel
Thanks for posting this! it helped me fix an issue created by skipping versions during upgrades.
This is a really helpful video about a complex topic. It’s very helpful to see how the arc of installation looks. Thank you very much.
Great new video. Thanks for doing it manual and without cephadm. Just tested the gateway on my testcluster with rclone and restic, works fine.
Thanks Daniel for this video. It really helped me to get the radosgw up.
Thank you for very informative video!
Appreciate the video and the gist! What's the next ceph video you're thinking of 🙂
