Hi,
Sorry guys, during theese days I'm asking a lot about how to distribute my
data.
I have two kinds of VM:
1.- Management VMs (linux) --> Full SSD dedicated disks
2.- Windows VM --> SSD + HHD (with tiering).
I'm working on installing two clusters on the same host but I'm
encountering lots of
If I'm understanding you correctly, you want to have 2 different roots that
pools can be made using. The first being entirely SSD storage. The second
being HDD Storage with an SSD cache tier on top of it.

The rules in the CRUSH map will always be followed. It is not possible for
Ceph to go against that and put data into a root that shouldn't have it.
The problem with a cache tier is that Ceph is going to need to promote and
evict stuff all the time (not free). A lot of people that want to use SSD
Thanks a lot David,
for me is a little bit difficult to make some tests because I have to buy a
hardware... and the price is different with cache ssd tier o without it.
If anybody have experience with VDI/login storms... will be really welcome!
Note: I have removed the ceph-user list because I g

Do you mean a lot of snapshots or creating a lot of clones from a snapshot?
I can agree to the pain of crating a lot of snapshots of rbds in ceph. I'm
assuming that you mean to say that you will have a template rbd with a
version snapshot that you clone each time you need to let someone log in.

Hi,
Yes, you are right, the idea is cloning a snapshot taken from the base
image...
And yes, I'm working with the current RC of luminous.
In this scenario: base image (raw format) + snapshot + snapshot clones
(for end user Windows 10 vdi). Does tiering ssd+hdd may help?
Thanks a lot

Hi,
For VDI (Windows 10) use case... is there any document about the
recommended configuration with rbd?
Thanks a lot!
