Hi All,
I was trying to define QoS on volumes in the openstack setup. Ceph Cluster
is configured as Storage back-end for images and volumes.
As part of my experimentation i thought of clubbing few disks (say HDD)
with one type of QoS and other few disks (say SSD) with another type of QoS.
But

Hi vikrant
Yes , its possible to have this , but if you follow best practices its not
recommended.
Under this scenario , if you have let suppose 5 disks tied to one OSD daemon
and by any reason if the OSD daemon stops working , you would loose all 5
drives in a row.
Good to know the reason

yes, Iwant to use multiple
hard drives with a single OSD.Is it possible to
have it?
It' s perfectly possible, but at the expense of redundancy, resilience
and/or speed. You can use some RAID, then loosing one hardrive (or
more,
Hi All,
I have one quick question -
Is it possible to have One Ceph-OSD-Daemon managing more than one Object
Storage Device in a Ceph Cluster?

AFAIK, one ceph-osd daemon is tied to single OSD, identified by osd-num and
data path.

Hi,
With Ceph, an OSD is generally one Ceph ceph-osd daemon for one storage
drive within a host machine. If your host has multiple storage drives, you
may map one ceph-osd daemon for each drive.
But , in your condition what I would suggest that make a volume group out
of all physical hard
