Introduction
This article aims to provide a solution for users who encountered an issue during the Debian 12 installation on a QNAP TS-262 NAS, where two NVMe SSD disks were not showing up for guided partitioning.Hardware Configuration
In this scenario, we have a QNAP TS-262 NAS with two 512GB NVMe SSD disks and two 8TB WD Red HDD disks. The user started installing Debian 12 using the QNAP OS, but they were not satisfied with the performance and decided to combine the two NVMe disks to create a RAID 1 array.Issue Description
During the Debian 12 installation process, the user encountered an issue where the two NVMe SSD disks were not showing up for guided partitioning.Check Disk Identification
First, check if the disks are properly identified by the NAS. Go to the QNAP Control Panel, click on "Storage & Snapshots," and then click on "Manage."
Make sure the two NVMe SSD disks are listed under "Disk 1" and "Disk 2." If not, power cycle the NAS and check again.
Update Firmware
Update the NAS firmware to the latest version. Go to the QNAP website, download the latest firmware, and install it using the QNAP OS.
Enable NVMe Support
Enable NVMe support in the QNAP OS. Go to "Control Panel" > "System" > "Hardware" > "NVMe SSD," and then enable the "Enable NVMe SSD Support" option.
Install Debian Manually
If the issue persists, install Debian manually. Boot the NAS using a Debian Live USB, and then create a RAID 1 array using the following steps:
sudo fdisk -l
sudo mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/nvme0n1p1 /dev/nvme1n1p1
sudo mkfs.ext4 /dev/md0
sudo mount /dev/md0 /mnt
Then, continue with the Debian installation as usual.
Summary
- Check if the disks are properly identified by the NAS.
- Update the NAS firmware to the latest version.
- Enable NVMe support in the QNAP OS.
- Install Debian manually if the issue persists.
