[ceph-users] Re: Issue adding host with cephadm - nothing is deployed

If you try shuffling some daemon around on some of the working hosts (e.g. changing the placement of the node-exporter spec so that one of the working hosts is excluded so the node-exporter there should be removed) is cephadm able to actually complete that? Also, does device info for any or all of

[ceph-users] Re: Issue adding host with cephadm - nothing is deployed

Okay, the fact that the removal is also not working means that idea of it being "stuck" in some way is likely correct. The most likely culprit in these scenarios in the past, as mentioned previously, are hanging ceph-volume commands. Maybe going to each of these new hosts and running something like

[ceph-users] Looking for Companies who are using Ceph as EBS alternative

Hey Folks, I have recently joined the Ceph user group. I work for Twitter in their Storage Infrastructure group. We run our infrastructure on-prem. We are looking at credible alternatives to AWS EBS(Elastic Block Storage) on-prem. We want to run our OLTP databases with remotely mounted drives. My

[ceph-users] Request for Info: What has been your experience with bluestore_compression_mode?

Hi everyone, We sent an earlier inquiry on this topic asking how many people are using bluestore_compression_mode, but now, we would like to know about users' experience in a more general sense. *Do you currently have bluestore_compression_mode enabled? Have you tried enabling it in the past? Have

[ceph-users] cephfs and samba

Hello there, is anybody sharing his ceph filesystem via samba to windows clients and willing to share his experience as well as settings in smb.conf and ceph.conf which have performance impacts? We are running this setup for years now, but i think there is still room for improvement and learn

[ceph-users] Re: Request for Info: What has been your experience with bluestore_compression_mode?

Hi Laura, We have used pool compression in the past and found it to work well. We had it on 4/2 EC pool and found data ended up near 1:1 pool:raw. We were storing backup data in this cephfs pool, however we changed the backup product and as the data is now encrypted at rest by the application the b

[ceph-users] Questions about the QA process and the data format of both OSD and MON

Hi, As I described in another mail(*1), my development Ceph cluster was corrupted when using problematic binary. When I upgraded to v16.2.7 + some patches (*2) + PR#45963 patch, unfound pgs and inconsistent pgs appeared. In the end, I deleted this cluster. pacific: bluestore: set upper and lowe

I've used RBD for Openstack clouds from small to large scale since 2015. Been through many upgrades and done many stupid things, and it's still rock solid. It's the most reliable part of Ceph, I'd say. On Fri, Aug 19, 2022 at 3:47 AM Abhishek Maloo wrote: > Hey Folks, > I have recently joined t

[ceph-users] Re: Looking for Companies who are using Ceph as EBS alternative

I agree with others who have described RBD as rock solid. Lots of people use RBD, especially for virtualization. DigitalOcean’s and Vultr's block service is Ceph, for example, and lots of OpenStack Cinder deployments. Not an EBS replacement as such because AWS isn’t being used in the first pl
