Disks showing up twice / multipath / ceph

This is my first time working with Proxmox

I am trying to build a 4 node cluster with proxmox and install ceph. I want to have a single location for my windows machines to access plex, files, photos, music.
After 4 day I am still having problems.

I have 4 used supermicro servers
2x 240GB SSD in raid 1 for boot
2 x 1TB nvme on motherboard (not being used at the moment)
with 2 x 10g nic's, 2 x 1g nic's, 1 x ipmi
1 x hba 9500i plugged into the hard drive backplane 12 slots only 2 filled for setup

I have installed proxmox over and over again and I might be starting to getting good at it.
I set up four nodes pve1, pve2, pve3, pve4

I have clustered the nodes together. I kept having problems and error messages but got it running on 1 of the 1g nic's. I'm hoping once everything is running I will be able to get the 10g nic's working for frontend and backend ceph networks.

I have installed Ceph on the 4 nodes added mon's and mgr's

All pve's are having the same problems. When trying to Create Osd's it fails with the message (command 'ceph-volume lvm create --crush-device-class hdd --data /dev/sdc' failed: exit code 1)

I think the problem is that the hard drives are showing up twice as sdc and sde

I did a test and was able to make an osd out of 1 of the nvme drives just fine.

I've looked into multipath and making a config file but it might not be correct and multipath doesn't seem to be working

Please help I am getting very frustrated with Proxmox at this point.

Here is my /etc/multipath.conf

defaults {
polling_interval 2
path_selector "round-robin 0"
path_grouping_policy multibus
uid_attribute ID_SERIAL
rr_min_io 100
failback immediate
no_path_retry queue
user_friendly_names yes
}

blacklist {
wwid .*
}

blacklist_exceptions {
wwid "35000c500e8d8ab61"
wwid "350014ee20b402e3e"
}

multipaths {
multipath {
wwid "35000c500e8d8ab61"
alias A1
}
multipath {
wwid "350014ee20b402e3e"
alias B1
}
}



multipath -ll returns no output

Update: I solved my own problem. I never did get multipath do work but while continuing my research I came upon a solution. My 950016i HBA has 2 x SFF-8654 ports. The port is supposed to handle 8 hard drives and there are to for a total of 16 drives. With break out cables the took the 2x SFF-8654 ports to 4x SFF-8643 ports. There are 4x 8643 ports on the back of the. I made a logical assumption that if I had 12 hard drives I would need to plug in at least 3 of the connectors. I plugged in all 4 which wasn't necessarily the whole problem. I turns out that the backplanes that I have are meant to be daisy changed together. The bottom 2 are incoming from the HBA and the upper 2 are meant to be plugged into the bottom of the next backplane if you have one. With only one you are only supposed to use the bottom 2 ports and leave the upper 2 open. I would think this would mean that you would only get to use 8 hard drives but it turns out that the server sees all 12. I don't know if I will get the full bandwidth of the HBA but if not hopefully its not too bad. At least now I can access all 12 drives from Ceph inside of Proxmox with no more errors.
