Re: [ceph-users] installation docs

Hi Manuel I am Goncalo Borges (Portuguese) and I work at the university of Sydney. We have been using ceph and cephfs since almost two years. If you think worthwhile, we can just talk and discuss our experiences. There is good ceph community in Melbourne but you are actually the first one in Syd

Hi, I have several questions regarding kernel running on client machines: * Why is kernel 3.10 considered an old kernel to run ceph clients? * Which features are missing? * What would be the impact of running clients on centos7.3 (kernel 3.10) compared to using a highe

Re: [ceph-users] How to know if an object is stored in clients?

Re: [ceph-users] Unbalanced OSD's

The best practice to reweight OSDs is to run test-reweight-by-utilization which is dry-run of reweighting OSDs before running reweight-by-utilization. On Sat, Dec 31, 2016 at 3:05 AM, Brian Andrus wrote: > We have a set it and forget it cronjob setup once an hour to keep things a > bit more balan

Re: [ceph-users] Unbalanced OSD's

We have a set it and forget it cronjob setup once an hour to keep things a bit more balanced. 1 * * * * /bin/bash /home/briana/reweight_osd.sh 2>&1 | /usr/bin/logger -t ceph_reweight The script checks and makes sure cluster health is OK and no other rebalancing is going on. It will also check the

[ceph-users] installation docs
