Which kind of SSD are you using, right now, as journal ?

Kurt,
When you had OS and osd journals co-located, how many osd journals were
on the SSD containing the OS?
You mention you now use a 5:1 ratio. Was the ratio something like 11:1
before (one SSD for OS plus 11 osd journals to 11 OSDs in a 12-disk
chassis)?
Also, what throughput per drive w

I would never run your journal in RAID-1 on SSDs. It means you'll 'burn'
through them at
Thank's Kurt,
That's comfort me in my decision to separate OS and Journal.

Hi,
we had a setup like this and ran into trouble, so I would strongly
discourage you from setting it up like this. Under normal circumstances
there's no problem, but when the cluster is under heavy load, for
example when it has a lot of pgs backfilling, for whatever reason

Hi,
Here my scenario :
I will have a small cluster (4 nodes) with 4 (4 TB) OSD's per node.
I will have OS installed on two SSD in raid 1 configuration.
Is one of you have successfully and efficiently a Ceph cluster that is
built with Journal on a separate partition on the OS SSD's?
I know
