Re: [ceph-users] Installing calamari on centos 7

[Ignacio Bravo]

Shailesh,

I was trying to do the same, but came across several compiling errors, 
that I decided to deploy the Calamari Server on a Centos 6 machine. Even 
then I was not able to finalize the installation.


See:
http://lists.ceph.com/pipermail/ceph-users-ceph.com/2015-May/001543.html
http://lists.ceph.com/pipermail/ceph-users-ceph.com/2015-May/001638.html

Now I feel less lonely in the deployment of Calamari since you are 
already in the same boat as myself.

Please keep me updated on your progress.

IB

They are written for centos 6. I tries using them but did not work.


Has anyone tried installing calamari on Centos 7?

Thanks.

[ceph-users] [Calamari] Build Calamari for Centos 7 nodes

[Ignacio Bravo]

All,

I have looked at the various guides in ceph.com related to building and 
deploying Calamari, and they will build the RPMs based on CentOS 6 or 
Red Hat 7, but not CentOS 7.


I have no problem with the OS of the Calamari server, as I am thinking 
in creating a VM for this, and Ubuntu or Centos will work either way, 
although I already have a Centos 7 server that would prefer to install into.


But my big issue are the ceph nodes, as they are currently running on 
CentOS 7 and the RPM created for Calamari via Vagrant are based on 
CentOS 6. Can I drop the CentOS 6 RPM and expect them to work, or shall 
I build new CentOS 7 RPMs? If the later, does anyone has instructions on 
how to do so?


I created a new Vagrant machine based on C7 but the compilation 
finalized with errors, thus my interest in hearing your comments.


Thanks,
IB
