Hi !
I am also facing same issue for new proxmox server having 2 Discs 1T and SSD and 2TB HDD , However only see 1 in GUI but lslb showing 2 drives
root@p8200prox:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 953.9G 0 disk
├─sda1 8:1 0 1007K 0 part
├─sda2 8:2 0 1G 0 part /boot/efi
└─sda3 8:3 0 952.9G 0 part
├─pve-swap 253:0 0 8G 0 lvm [SWAP]
└─pve-root 253:1 0 944.9G 0 lvm /
sdb 8:16 0 1.8T 0 disk
├─sdb1 8:17 0 1.8T 0 part
└─sdb2 8:18 0 750M 0 part
I read the post reponses and ran command sgdisk --zap-all /dev/sdb but seeing the below out put :
root@p8200prox:~# sgdisk --zap-all /dev/sdb
Warning: Partition table header claims that the size of partition table
entries is 0 bytes, but this program supports only 128-byte entries.
Adjusting accordingly, but partition table may be garbage.
Caution: invalid main GPT header, but valid backup; regenerating main header
from backup!
Caution! After loading partitions, the CRC doesn't check out!
Warning: Invalid CRC on main header data; loaded backup partition table.
Warning! Main and backup partition tables differ! Use the 'c' and 'e' options
on the recovery & transformation menu to examine the two tables.
Warning! One or more CRCs don't match. You should repair the disk!
Main header: ERROR
Backup header: OK
Main partition table: ERROR
Backup partition table: ERROR
Invalid partition data!
GPT data structures destroyed! You may now partition the disk using fdisk or
other utilities.
Not sure about it - any help and guidance appreciated thanks
