Proxmox not seeing disk partition.

[Reginald182]

I am a brand new user to Proxmox and I currently have two nodes talking to each other but they do not have shared storage, just the default local LVM-Thin storage that is created on installation. I am trying to use Ceph and create an OSD so that both nodes can talk to the pool I have created. However Create OSD, Create ZFS, and Create Thinpool are not seeing the extra partition I have created. I have tried clearing the disk, changing the type, the flags, and repartitioning it but I can not get it to show up anywhere in Proxmox. Note - this is a partition on the same disk I have running Proxmox, is this even possible or do I need an entirely separate disk for OSD or ZFS? Here is my currently fdisk -l

Disk /dev/sda: 1.1 TiB, 1199168290816 bytes, 2342125568 sectors
Disk model: LSI2208iMR
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: gpt
Disk identifier: 4DAD36AB-110A-4460-99BD-8363035915C6

Device Start End Sectors Size Type
/dev/sda1 34 2047 2014 1007K BIOS boot
/dev/sda2 2048 1050623 1048576 512M EFI System
/dev/sda3 1050624 1677721600 1676670977 799.5G Linux LVM
/dev/sda4 1677723648 2342125534 664401887 316.8G Linux LVM

/dev/sda4 is the partition I am currently having issues with. Thanks for any and all help!

Using Ceph on partitions instead of disks is not ideal. See, for example, these posts:

Cool thanks for that information, I will add some new disks to the server.
