[ceph-users] Soft removal of RBD images

Hi, Since Ceph Hammer we can protect pools from being removed from the cluster, but we can't protect against this: $ rbd ls|xargs -n 1 rbd rm That would remove all not opened RBD images from the cluster. This requires direct access to your Ceph cluster and keys with the proper permission, but

Re: [ceph-users] Ceph Openstack deployment

There must be something in /var/log/cinder/volume.log or /var/log/nova/nova-compute.log that points to the problem. Can you post it here? 2015-11-06 20:14 GMT+08:00 Iban Cabrillo : > Hi Vasilly, > Thanks, but I still see the same error: > > cinder.conf (of course I just

Re: [ceph-users] Ceph Openstack deployment

Hi, One more step debugging this issue (hypervisor/nova-compute node is XEN 4.4.2): I think the problem is that libvirt is not getting the correct user or credentials tu access pool, on instance qemu log i see: xen be: qdisk-51760: error: Could not open

Re: [ceph-users] Ceph Openstack deployment

At cinder.conf you should place this options: rbd_user = cinder rbd_secret_uuid = 67a6d4a1-e53a-42c7-9bc9-xxx to [rbd-cephvolume] section instead of DEFAULT. 2015-11-06 19:45 GMT+08:00 Iban Cabrillo : > Hi, > One more step debugging this issue

Hi Philipp, I see you only have 2 osds, have you check that your "osd pool get size" is 2, and min_size=1?? Cheers, I 2015-11-06 22:05 GMT+01:00 Philipp Schwaha : > On 11/06/2015 09:25 PM, Gregory Farnum wrote: > > >
