Hi, there!I am Cristina. I have a Linux LVM(1.7T) with RAID5. Now I want to mount a ssd(SATA) to one of my pve node(VM ID=700).
----------------------------
Device Start End Sectors Size Type
/dev/sda1 34 2047 2014 1007K BIOS boot
/dev/sda2 2048 262143 260096 127M EFI System
/dev/sda3 262144 3512991710 3512729567 1.7T Linux LVM
-----------------------------
My ssd(/dev/sdb) is shown in pve after I do RAID0 on my ssd. But it not shown in node 700.
---------------------------------
fdisk -l (pve)
Disk /dev/sdb: 232.4 GiB, 249510756352 bytes, 487325696 sectors

fdisk -l (node 700)

/dev/sda1 * 1 64 512000 83 Linux
Partition 1 does not end on cylinder boundary.

Disk identifier: 0x00000000
------------------------------------
I want to mount SSD to my pve node(700) not the whole pve. That is to say, I want to see ssd(/dev/sdb) on my node 700 like below.

fdisk -l (node 700)

------------------------------------
/dev/sdb ext4 233G 60M 221G 1% /mnt/ssd
It can be mounted on pve instead of pve node(700).
I want to the node and pve cluster share disk SSD(/dev/sdb) or /dev/sdb is on my node(700).
Thanks, everyone!
