Wow, you made it farther than I did. I got it installed, added hosts, then NOTHING. It showed there were physical disks on the hosts but wouldn't create the OSDs. Command was accepted, but NOTHING happened. No output, no error, no NOTHING. I fought with it for over a week and finally gave up, as with no feedback as to what the issue is it's impossible to troubleshoot. A product that does NOTHING isn't a product at all. I posted a detailed message here with screenshots, steps, everything somebody would need to reproduce my situation. The post got blocked because it was too big and sent for moderation. It never got approved or rejected. So I moved on, can't be using something that does NOTHING with no way to proceed past that point. ________________________________ From: Roberto Maggi @ Debian <debian108@xxxxxxxxx> Sent: April 24, 2024 01:39 To: Ceph Users <ceph-users@xxxxxxx> Subject: ceph recipe for nfs exports [You don't often get email from debian108@xxxxxxxxx.
