[ceph-users] Ceph repo is broken, no repodata at all

Hi list, I found that ceph repo is broken these days, no any repodata in the repo at all. http://us-east.ceph.com/rpm-jewel/el7/x86_64/repodata/ it's just empty, so how can I install ceph rpms from yum? A workaround is I synced all the rpms to local and create repodata with createrepo command,

[ceph-users] rbd pool:replica size choose: 2 vs 3

Hi there, the default rbd pool replica size is 3. However, I found that in our all ssd environment, capacity become a cost issue. We want to save more capacity. So one option is change the replica size from 3 to 2. anyone can share the experience of pros vs cons regarding replica size 2 vs 3? than

[ceph-users] Question on RGW MULTISITE and librados

Fairly new to ceph so please excuse any misused terminology. We're currently exploring the use of ceph as a replacement storage backend for an existing application. The existing application has 2 requirements which seemingly can be met individually by using librados and the Ceph Object Gateway

Re: [ceph-users] [EXTERNAL] Re: jewel blocked requests

Thanks for responding, and I apologize for taking so long to get back to you. But all the osds are ceph version 10.2.2 The osd with the bad disk is down and out of the cluster. The disk may get replaced today. I'm still getting blocked request messages, but at a significantly lower rate.

Re: [ceph-users] too many PGs per OSD when pg_num = 256??

Nothing weird, I have incomplete data and data based on bad rounding errors. Your cluster has too many pgs and most of your pools will likely need to be recreated with less. Have you poked around on the pg calc tool? [cid:image7765b4.JPG@f8b09f63.48b63161]

Hmm. Something happened then. I only have 20 OSDs. What may cause that? Brian Andrus ITACS/Research Computing Naval Postgraduate School Monterey, California voice: 831-656-6238 From: David Turner [mailto:david.tur...@storagecraft.com] Sent: Thursday, September 22, 2016 10:04 AM To: Andrus, Bria

Re: [ceph-users] too many PGs per OSD when pg_num = 256??

So you have 3,520 pgs. Assuming all of your pools are using 3 replicas, and using the 377 pgs/osd in your health_warn state, that would mean your cluster has 28 osds. When you calculate how many pgs a pool should have, you need to account for how many osds you have, how much percentage of data

Re: [ceph-users] too many PGs per OSD when pg_num = 256??

How many pools do you have? How many pgs does your total cluster have, not just your rbd pool? ceph osd lspools ceph -s | grep -Eo '[0-9] pgs' My guess is that you have other pools with pgs and the cumulative total of pgs per osd is too many. [cid:image07e234

[ceph-users] Give up on backfill, remove slow OSD

Hi, I currently have an OSD that has been backfilling data off it for a little over two days now, and it's gone from approximately 68 PGs to 63. As data is still being read from, and written to it by clients whilst I'm trying to get it out of the cluster, this is not helping it at all. I figured
