2014-12-06 Thread Loic Dachary
Hi Joao, This question looks like it should have an easy answer, but I've never tried to do that. Does anyone has previous experience dealing with this ? Cheers Quoting : http://tracker.ceph.com/issues/9485#note-19 After trying to edit the crushmap in order to separate groups of OSDs

[ceph-users] Integration of Ceph Object Gateway(radosgw) with OpenStack Juno Keystone

2014-12-06 Thread Vivek Varghese Cherian
Hi, I am trying to integrate OpenStack Juno Keystone with the Ceph Object Gateway(radosw). I want to use keystone as the users authority. A user that keystone authorizes to access the gateway will also be created on the radosgw. Tokens that keystone validates will be considered as valid by the

2014-12-06 Thread Nick Fisk
Hi Loic, A very interesting reply and your description of the promotion behaviour makes perfect sense. I can see how a larger number of data chunks could impact latency, so would certainly impact a OLTP type workload where low latency is critical. Would you know if the promotion/EC pool read

Hi David, Very strange, but I'm glad you managed to finally get the cluster working normally. Thank you for posting the benchmarks figures, it's interesting to see the overhead of LIO over pure RBD performance. I should have the hardware for our cluster up and running early next year, I will

[ceph-users] normalizing radosgw

2014-12-06 Thread Sage Weil
Several things are different/annoying with radosgw than with other Ceph daemons: - binary/package are named 'radosgw' instead of 'ceph-rgw'. This is cosmetic, but it also makes it fit less well into the new /var/lib/ceph/* view of things. - default log location is

Sage, at least in the Redhat world there are ways to get a pre-assigned uid/gid for a service that is part of a system service. There's a registered list of services that get fixed uid/gid, you can google for it. Any service can add an adduser command with a fixed uid/gid but best to

You can also register uids with Debian. Quoting from the Policy Manual[1]: The UID and GID numbers are divided into classes as follows: 0-99: Globally allocated by the Debian project, the same on every Debian system. These ids will appear in the passwd and group

Sorry, I'm afraid I can't anymore. At the time the logs didn't seem very interesting, which was why I didn't attach any to my original e-mail. On the virtualization guests there was a disk error and the drive was remounted read-only. I don't have remote logging, so there was nothing after that. On

I should have kept reading the policy manual. The relevant section seems to be: 6-64999: Globally allocated by the Debian project, but only created on demand. The ids are allocated centrally and statically, but the actual accounts are only created on users' systems on demand. The changelog
