Missing Disks

[Arthur Stephens]

I originally setup my ceph cluster machines with 2 disks raid one for the Proxmox install and the other 6 drives as a raid array which I used for the cepf OSD. I later read that ceph works better if you do not do raid so I removed the raid config for the 6 drive. But when I rebooted the node there is only the one 2 disk drive and no other drives available to set up the OSD. Do I have to re-install Promox 4 in order for the other six drive to show up?

Hi,
an pve-reinstall will not help (it's no windows).

It's depends on your raid-controller, in the best way you can use "IT-mode" for your OSD-Disks, or path through, how other companies called this function.
If you have an not brand new lsi-controller you must define for every single disk an raid 0!! This is like lsi understand path through - don't know which shit they smoke...
