Maybe this is more a question about logics. I would by default always go

troubleshoot best, knows your team, you have made a conscious choice in
the past for this etc. And deviating from this should be backed by good
argumentation.
I think so.
Afaik the newer kernel is only necessary for ceph clients, so if you
don’t do something hyper converged there is no need to get it (verify
this). So first decide what you need, then see if your default setup is
able of handling this.
So Ceph server side don't need latest kernel.
It's just the client that need it... is it so?
This should be explained better in the docs.
As a side note, I am running CentOS7 testcluster, installing the elrepo
kernel gave me some booting problems because of the mpt2sas driver
changes, but nothing that cannot be fixed with a little time an effort.
There is also different kernel ofered here. But you have to search the
archives where it is located.
Not good.
I'm not worried about time and effort.
I'm worried to fix this while there is not time.
Ceph is builded to avoid downtime, not a good idea create it on an a
system with availability issues.

Subject: Linux Distribution: Is upgrade the kerner version
a good idea?
Hi everybody,
Just a simple question.
In order to deploy Ceph...
Do you'll use a default distribution that already support
recommended kernel version (> 4.4).
Let's say Ubuntu.
OR
Do you'll use your preferred linux distribution and just upgrade it
to a higher kernerl version.
Let's say CentOS.
... and a bonus question:
Is upgrade the kernel to major version on a distribution a bad idea?
Or is just safe as like as upgrade like any other package?
I prefer ultra stables release instead of latest higher package.
But maybe I'm in wrong thinking that latest major kernel not in the
default repository is likely say "dev distribution" and instead is just
a stable release as like every others.
Thanks for all your tips, opinion and clarification! :)
