Re: [ceph-users] Motherboard recommendation?

Hi Nick, Thanks Nick for your reply. There is a clear picture on the hardware requirement for replication( 1Ghz per osd). But We cant find any document related to hardware recommendation for erasure coding.I read the mark nelson report. But still some erasure coding testing shows 100% CPU utiliza

Re: [ceph-users] Motherboard recommendation?

Hi Mohamed, I asked Mark the exact same question about his report, on his test hardware he had slightly less than 1GHZ per OSD so he was fairly sure the guideline was still reasonable accurate. However it's hard to come up with an exact figure as the CPU usage will change with the varying K/M

Re: [ceph-users] Rados Gateway and keystone

Hi, I finally configure a cloudberry profile by setting what seems to be the right endpoint for object storage according to the openstack environment : myrgw:myport/swift/v1 I got a “204 no content” error even if 2 containers were previously created by a swift operation with object into them.

[ceph-users] Ceph.com

Hey cephers, As most of you have no doubt noticed, ceph.com has been having some...er..."issues" lately. Unfortunately this is some of the holdover infrastructure stuff from being a startup without a big-boy ops plan. The current setup has ceph.com sharing a host with some of the nightly build st

Re: [ceph-users] Ceph.com

Thanks for working on this Patrick. I have looked for a mirror that I can point all the ceph.com references to in /usr/lib/python2.6/site-packages/ceph_deploy/hosts/centos/install.py. So I can get ceph-deploy to work. I tried eu.ceph.com but it does not work for this Dan Ferber Software Defi

Re: [ceph-users] Ceph.com

We've fixed it so that 404 handling isn't done by wordpress/php and things are muuuch happier. We've also moved all of the git stuff to git.ceph.com. There is a redirect from http://ceph.com/git to git.ceph.com (tho no https on the new site yet) and a proxy for git://ceph.com. Please let us

Thanks for the update, Patrick. Our Docker builds were failing due to the mirror being down. I appreciate being able to check the mailing list and quickly see what's going on! Chris On Thu, Apr 16, 2015 at 11:28 AM, Patrick McGarry wrote: > Hey cephers, > > As most of you have no doubt noticed,

[ceph-users] switching journal location

If my cluster is quiet and on one node I want to switch the location of the journal from the default location to a file on an SSD drive (or vice versa), what is the quickest way to do that? Can I make a soft link to the new location and do it without restarting the OSDs? -- Tom Deneau, AMD ___

Re: [ceph-users] switching journal location

Hi Tom, you will have to stop the OSD, flush the existing journal to ensure data consistency at the OSD level and then switch over to the new journal location (initialise journal then start the OSD). Visit this link for step by step from Sébastien : http://lists.ceph.com/pipermail/ceph-users-c

Re: [ceph-users] OSDs not coming up on one host

The monitor looks like it's not generating a new OSDMap including the booting OSDs. I could say with more certainty what's going on with the monitor log file, but I'm betting you've got one of the noin or noup family of flags set. I *think* these will be output in "ceph -w" or in "ceph osd dump", a

Re: [ceph-users] ceph-osd failure following 0.92 -> 0.94 upgrade

Yeah, you're going to have to modify one of the journal readers. I don't remember exactly what the issue is so I don't know which direction would be easiest — but you (unlike the Ceph upstream) can have high confidence that the encoding bug is caused by v0.92 rather than some other bug or hardware

[ceph-users] Cache-tier problem when cache becomes full
