To add to this ticket in case this is useful for someone else. Using the above hardware for the past 5-6months has been flawless and a brilliant system. Another useful piece of info for Alwin, Dell has finally seen the light and I see that they have a new firmware update for the h740p raid...

Apologies, I have not been able to post those logs. Paternity and all that. I have left my test case in staging for all this time, and just for anyone else having the issue - upgrading to the latest 12.2.7 has solved the issue. I cannot get problems when adding zapping 6 osds from a host and...

I appreciate the reply - I have just removed the disks (osd.12 to osd.17) again from the 4th node, zapped them, unmounted the rockdb partition and then recreated them with pvecreate. within 5 seconds of recovery I get blocked requests, the osds having the blocked requests are not any of the...

"This can be already the reason, why the ceph cluster shows slow requests. Ceph needs to know about its OSDs/disks. A raid controller masks or even lies about the disks. Most controller leave the cache and its algorithms in place, even when used as JBOD. Use HBAs for ceph (counts even for zfs)...

Hmm seems that debian stretch has the same problem. Funny thing is that the network cards work perfectly fine once the iso is able to install and ive rebooted into proxmox - Ive tried everything to get the drivers to load but to no avail. I will put it down to land sharks for now. I have found...
