[ceph-users] v0.83 released

Another Ceph development release! This has been a longer cycle, so there has been quite a bit of bug fixing and stabilization in this round. There is also a bunch of packaging fixes for RPM distros (RHEL/CentOS, Fedora, and SUSE) and for systemd. We've also added a new librados-striper libra

Re: [ceph-users] Force CRUSH to select specific osd as primary

Sound good, but there is one problem. In my case I'll have as many hosts as pools used by some piece of software (via librados), and for performance purposes I want to put my primary osd for each pool on the same host as software. In that scenario I'll end up with as many new roots as hosts and I t

[ceph-users] v0.80.5 Firefly released

This release fixes a few important bugs in the radosgw and fixes several packaging and environment issues, including OSD log rotation, systemd environments, and daemon restarts on upgrade. We recommend that all v0.80.x Firefly users upgrade, particularly if they are using upstart, systemd, or r

Re: [ceph-users] Force CRUSH to select specific osd as primary

You could create a new root bucket which contains hosts 2 and 3; then use it instead of "default" in your special rule. That's probably what you want anyway (rather than potentially having two copies of the data on host 1). -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com On Tue

[ceph-users] Force CRUSH to select specific osd as primary

I have 3 osd on 3 different hosts: host1 host2 and host3. I'm trying to force CRUSH to use osd on host1 as primary for one of my pools. I can't use primary-affinity because i don't want to set this osd as primary for all my pools. I try to create simple CRUSH rule, which should select osd on host1

Just went through the output a couple more times and noted that you have a mix of 'el6' and 'el7' packages: > [monitor01][DEBUG ] ---> Package mesa-libglapi.x86_64 0:9.2.5-5.20131218.el7 > will be installed > [monitor01][DEBUG ] ---> Package python-ceph.x86_64 0:0.80.4-0.el6 will be > installed

Christian - Thank you for the answer, I'll get around to reading 'Crush Maps ' a few times , it is important to have a good understanding of ceph parts. So another question - As long as I keep the same number of nodes in both rooms, will firefly defaults keep data balanced? If not I'll
