Hi,
I have four old machines lying around. I would like to setup ceph on

Are there any screencast or tutorial with commands, on how to obtain,

Hi Simon,
thanks for your reply.
I already installed OS for my ceph-nodes via Kickstart (via network) from

also been done.

Thank you very much - I think I've solved the whole thing. It wasn't in
radosgw.
The solution was,
- increase the timeout in Apache conf.
- when using haproxy, also increase the timeouts there!

Those settings are applied when creating new pools with "osd pool

Hello,
I’m running a 3 node cluster with 2 hdd/osd and one mon on each node.
Sadly the fsyncs done by mon-processes eat my hdd.
I was able to disable this impact by moving the mon-data-dir to ramfs.
This should work until at least 2 nodes are running, but I want to implement

Hi John.
Thanks for the reply, sounds very good.
The extra visualizations from kibana (grafana only seems to pack a

Looking forward to some calamari.
