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 any
Hello,
I am having and issue with CEPH in that it won't communicate over the
private network so the moment I turn the firewalls on then it will start
marking OSD's offline. I have specified in the ceph.conf file that it has a
separate cluster network but it looks like it is not obeying my orders.
Hi!
I have installed ceph and created two osds and was very happy with that
but apparently not everything was correct.
Today after a system reboot the cluster comes up and for a few moments
it seems that it's ok (using the "ceph health" command) but after a few
seconds the "ceph health" com
My setup consists of two nodes.
The first node (master) is running:
-mds
-mon
-osd.0
and the second node (CLIENT) is running:
-osd.1
Therefore I 've restarted ceph services on both nodes
Leaving the "ceph -w" running for as long as it can after a few seconds

Actually there are two monitors (my bad in the previous e-mail).
One at the MASTER and one at the CLIENT.
The monitor in CLIENT is failing with the following

Hi Alexandre,
Can you tell me the version of libvirt, qemu and OS you use? thanks.
Thanks & Regards

Thank you
Hello,
I don't use libvirt (i'm using proxmox solution + qemu 1.7).
discard is supported since qemu 1.5, but i'm not sure about the rbd block
driver. (maybe 1.6)
I'm using virtio-scsi in guest

It is not a requirement but it is definitely easier because it uses a
lot of defaults and well known conventions

Hello all,
Recently I am working on Ceph performance analysis on our cluster, our OSD
hardware looks like:
11 SATA disks, 4TB for each, 7200RPM
48GB RAM
When break down the latency, we found that half of the latency (average latency
is around 60 milliseconds via radosgw) comes from file loo

Hi,
We experience something similar with our Openstack Swift setup.
You can change the sysstl "vm.vfs_cache_pressure" to make sure more inodes are
being kept in cache.
(Do not set this to 0 because you will trigger the OOM killer at some point ;)
We also decided to go for nodes with more memory
