Hi,
I have defined pool hdd which is exclusively used by virtual disks of

Yesterday I run these commands

However since then no KVM / LXC is reacting anymore.

Thank you, Yan.
It took like 10 minutes to execute the scan_links.
I believe the number of Lost+Found decreased in 60%, but the rest of

Any other suggestion?

Hi Robert,
So far the cloud tiering features are still in the design stages. We're
working on some initial refactoring work to support this abstraction
(ie. to either satisfy a request against the local rados cluster, or to
proxy it somewhere else). With respect to passthrough/tiering to AWS,
bump. anyone?

Hi Robert,
As long as you triple-check permissions on the cache tier (should be the
same as your actual storage pool) you should be fine.
In our setup I applied this a few times. The first time I made the

That would be the case for me. I think all data during one day would fit into

Hi!
Cache tiering is a great solution if the cache size is larger than the hot
data. Even better if the data can cool quietly in the cache. Otherwise, it’s
really better not to do this.

I hope the data your running the CEPH server isn't important if your looking to
run a Cache tier with just 2 SSDS / Replication of 2.
If your cache tier fails, you basically corrupt most data on the pool below.
Also as Wido said, as much as you may get it to work, I don't think it will

We have terrible IO performance when multiple VMs do some file IO. Mainly do

Have you checked that the user/keys that your VMs are connecting to have access
rights to the cache pool?
