[ceph-users] Impossible to Create Bucket on RadosGW?

Hello, I'm horribly failing at creating a bucket on radosgw at ceph 0.67.2 running on ubuntu 12.04. Right now I feel frustrated about radosgw-admin for beeing inconsistent in its options. It's possible to list the buckets and also to delete them but not to create! No matter what I tried -

Re: [ceph-users] Performance issues with small files

Thats correct. We created 65k buckets, using two hex characters as the naming convention, then stored the files in each container based on their first two characters in the file name. The end result was 20-50 files per bucket. Once all of the buckets were created and files were being loaded, we

[ceph-users] newbie question: rebooting the whole cluster, powerfailure

Hi all, as a ceph newbie I got another question that is probably solved long ago. I have my testcluster consisting two OSDs that also host MONs plus one to five MONs. Now I want to reboot all instance, simulating a power failure. So I shutdown the extra MONs, Than shutting down the first OSD/MON

Re: [ceph-users] Performance issues with small files

Wouldn't using only the first two characters in the file name result in less then 65k buckets being used? For example if the file names contained 0-9 and a-f, that would only be 256 buckets (16*16). Or if they contained 0-9, a-z, and A-Z, that would only be 3,844 buckets (62 * 62). Bryan On Th

Re: [ceph-users] Performance issues with small files

based on your numbers, you were at something like an average of 186 objects per bucket at the 20 hour mark? I wonder how this trend compares to what you'd see with a single bucket. With that many buckets you should have indexes well spread across all of the OSDs. It'd be interesting to know

I need to restart the upload process again because all the objects have a content-type of 'binary/octet-stream' instead of 'image/jpeg', 'image/png', etc. I plan on enabling monitoring this time so we can see if there are any signs of what might be going on. Did you want me to increase the number

Larry, If you're talking about how to do that with libvirt and QEMU on CentOS6.4, you might look at http://openstack.redhat.com/Using_Ceph_for_Block_Storage_with_RDO. You just don't need to install and configure OpenStack, obviously. You do need to get the upstream version of QEMU from the Ceph re
