Osd's do not even use bonding effenciently. If it were to use 2 links
concurrently it would be a lot better.

This is a natural condition of bonding, it has little to do with ceph-osd.
Make sure your hash policy is set appropriatelly, so that you even have a
chance of using both links.

The larger the set of destinations, the more likely you are to spr
Hello,
what you see is an stracktrace, so the OSD is hitting an unexpected
state (Otherwise there would be an error handler).
The crash happens, when the osd wants to read from pipe when processing
heartbeat. To me it sounds like a networking issue.
I see the other OSD an that host are healthy,
You can optimize ceph-osd for this of course. It would benefit people
that like to use the 1Gbit connections. I can understand putting time
into it now does not make sense because of the availability of 10Gbit.
However, I do not get why this was not optimized already 5 or 10 years
ago.

Hello Dave,
you can configure Ceph to pick multiple OSDs per Host and therefore work
like a classic raid.
It will cause a downtime whenever you have to do maintenance on a system,
but when you plan to grow it quite fast, it's maybe an option for you.

Check if it's using 100% CPU for example. And check the disk util with
iostat.
