Re: [ceph-users] Starting radosgw - RHEL6.4

2014-01-31 Thread alistair.whittle
I have all this information in my ceph.conf file. My question was more about the executable itself and the fact that it differs from what I can see documented. It is not in the location mentioned in the docs (/usr/bin instead of /etc/init.d) and seems to want some parameters which is also not

Found the problem, I think. The executable IS in /etc/init.d, but it called 'ceph-radosgw', not 'radosgw' as per the documentation. -Original Message- From: Whittle, Alistair: Investment Bank (LDN) Sent: Friday, January 31, 2014 3:01 PM To: 'Derek Yarnell'; ceph-users@lists.ceph.co

Once OSDs are created by ceph-deploy, ceph udev rules recognise OSDs by GPT labels of their partitions. You can see how this happens in /lib/udev/rules.d/95-ceph-osd.rules (that's the path on an ubuntu server). Cheers, John On Thu, Jan 30, 2014 at 1:07 PM, Daniel Schwager wrote: > Hi, > > just

Hi list, I'm trying to play with ceph, but I can't get the machine to reach a clean state. How I did the installation: ceph-deploy new ceph-a1 ceph-deploy install ceph-a1 ceph-deploy mon create-initial ceph-deploy mon create ceph-a1 ceph-deploy gatherkeys ceph-a1 ceph-deploy disk zap ceph-a1:vd
