Re: [ceph-users] the state of cephfs in giant

Hello sage, last time I used CephFS it had a strange behaviour when if used in conjunction with a nfs reshare of the cephfs mount point, I experienced a partial random disapearance of the tree folders. According to people in the mailing list it was a kernel module bug (not using ceph-fuse) do

Re: [ceph-users] Openstack keystone with Radosgw

Right, So you have 3 osds, one of whom is a mon. Your rgw is on another host (called gateway it seems). I'm wondering if is this the issue. In my case I'm using one of my osds as a rgw as well. This *should* not matter... but it might be worth trying out a rgw on one of your osds instead. I'm

[ceph-users] radosGW balancer best practices

Dear all, we are going to add rados-gw to our ceph cluster (144 OSD on 12 servers + 3 monitors connected via 10giga network) and we have a couple of questions. The first question is about the load balancer, do you have some advice based on real-world experience? Second question is about th

Hello Mark - with rgw_keystone_url under radosgw section, I do NOT see keystone handshake. If I move it under global section, I see initial keystone handshake as explained earlier. Below is the output of osd dump and osd tree. I have 3 nodes (node1, node2, node3) acting as OSDs. One of them (nod

Re: [ceph-users] Icehouse & Ceph -- live migration fails?

Hi all, This issue is also affecting us (centos6.5 based icehouse) and, as far as I could read, comes from the fact that the path /var/lib/nova/instances (or whatever configuration path you have in nova.conf) is not shared. Nova does not see this shared path and therefore does not allow to perform

Thanks for theses informations. I plan to use CephFS on Giant, with production workload, knowing the risks and having a hot backup near. I hope to be able to provide useful feedback. My cluster is made of 7 servers (3mon, 3osd (27 osd inside), 1mds). I use ceph-fuse on clients. You wrote about h
