Hi, Im playing with this with a modest sized ceph cluster (36x6TB disks). Based on this it says that small pools (such as .users) would have just 16 PGs. Is this correct? I've historically always made even these small pools have at least as many PGs as the next power of 2 over my number of OSDs

I've had a tremendous difficultly using S3 command when using RGW. I've successfully used an older php client, but not s3cmd. For the moment, we're no longer using s3cmd with RGW, because it simply doesn't seem to work, other than for listing buckets. On Tue, Aug 12, 2014 at 10:52 AM, debian

Hello, We've previously tested RGW with small objects in the past (about 100 million in objects in the few KB size range) with emperor. We found that RGW ground almost to a halt. Based on discussion at the time, I understood the problem to be related to the index pool in which RGW stores the

I'm going to note that I've seen this on Firefly. I don't think it necessarily needs a named release, but I can confirm that it seems to be related to radosgw. All the best, ~ Christopher On Thu, Apr 24, 2014 at 10:33 AM, Gregory Farnum g...@inktank.com wrote: Yehuda says he's fixed several

Hello, There are several older discussions regarding RGW performance with high volume small files. I'm planning on running some tests on our test cluster to benchmark this performance, but before I do I wanted to ask several questions, to make sure that me test is valid. 1) does firefly have
