Re: [ceph-users] ceph-volume does not support upstart

You could add a file named  /usr/sbin/systemctl and add:
exit 0
to it.

Hello ceph-users!

I am a ceph user from china.
Our company deploy ceph on arm ubuntu 14.04. 
Ceph Version is luminous 12.2.2.
When I try to activate osd by ceph-volume, I got the following error.(osd 
prepare stage seems work normally)
It seems that ceph-volume only work under systemd, but ubuntu 14.04 does not 
support systemd.
How can I deploy osd in ubuntu 14.04 by ceph-volume?
Will ceph-volume support upstart in the future?

Re: [ceph-users] Cache tiering on Erasure coded pools

2017-12-28 Thread Karun Josy 
Hello David,

Thank you!
We setup 2 pools to use EC with RBD. One ecpool and other normal replicated
pool.

However, would it still be advantageous to add a replicated cache tier in
front of an EC one, even though it is not required anymore? I would still
assume that replication would be less intensive than EC computing?

[ceph-users] radosgw package for kraken missing on ubuntu

2017-12-28 Thread Robert Stanford 
 I am installing with ceph-deploy using the instructions at
http://docs.ceph.com/docs/master/install/get-packages/

 ceph-deploy runs fine for the first node until it dies due to not finding
radosgw package.  I have verified on that node (apt-cache search radosgw,
apt-get install radosgw) that this package is not available.

 Since I have followed the instructions on the page to make the Ceph
packages available, all others work fine.  Why isn't radosgw included?
