Hi Cephers
Just fired up first Infernalis cluster on RHEL7.1.
The following:
[root@citrus ~]# systemctl status ceph-osd@0.service
ceph-osd@0.service - Ceph object storage daemon
Loaded: loaded (/usr/lib/systemd/system/ceph-osd@.service; enabled)
Active: active (running) since Fri 2016-01-0
Hi Cephers and Happy New Year
I am under the impression that ceph was refactored to allow dynamic enabling of
lttng in Infernalis.
Is there any documentation on how to enable lttng in Infernalis? (I cannot
find anything…)
Regards
Paul

Seasons Greetings Cephers..
Can I assume that http://tracker.ceph.com/issues/12200 is fixed in Infernalis?
Any chance that it can be back ported to Hammer ? (I don’t see it planned)
We are hitting this bug more frequently than desired so would be keen to see it
fixed in Hammer

I could not find any usage in the Ceph source code except that the value is set

Hi Jan
If I can suggest that you look at:

I found the description in the source code. Apparently one sets attributes

One secret is to ensure that the disk is cleaned prior to ceph-disk

to purge the disk of all partition tables. We usually issue this command

Hi Ken
Are these packages compatible with Giant or Hammer?
We are currently running Hammer - can we use the RBD kernel module from
RH7.1 and is the elrepo version of cephFS compatible with Hammer?

There is a separate mail thread about being able to run clusters with different
conf files on the same host.
Will the new systemd service scripts cope with this?

I am using the ceph-disk command to prepare disks for an OSD.
The command is:

Hi Steffen
We have recently encountered the errors described below. Initially one must set
check_obsoletes=1 in the yum priorities.conf file.
However subsequent yum updates cause problems.
The solution we use is to disable the epel repo by default:
yum-config-manager --disable epel

Hi Wildo
Has something broken with this move? The following has worked for me repeatedly
over the last 2 months:
This a.m. I tried to install ceph using the following repo file:
[root@citrus ~]# cat /etc/yum.repos.d/ceph.repo
[ceph]
name=Ceph packages for $basearch
baseurl=http://ceph.com/rpm-
Thanks for that Travis. Much appreciated.
