Hallo all,
taking advantage of the redundancy of my EC pool, I destroyed a
couple of servers in order to reinstall them with a new operating system.
I am on Nautilus (but will evolve soon to Pacific), and today I am
not in "emergency mode": this is just for my education. :-)

We've been running into a mysterious issue on Ceph 16.2.7. Every few
weeks or so (can be from 2 weeks to a month and a half), we get
input/output errors on a random OSD. Here's the logs :

We have a system running Ceph Pacific with a large number of delete
