Troubleshooting Common Issues
When adding a whole hard drive to a Proxmox VM, you may encounter various issues. Here are common problems and their potential solutions:
1. The hard disk is not recognized by the VM
- Ensure that the hard disk is properly connected to the VM’s hardware.
- Check if the disk size is supported by the VM’s hardware configuration.
- Restart the VM and try again.
2. The VM freezes after adding the hard disk
- Check if the VM has sufficient resources, such as CPU and memory, to handle the additional disk.
- Update the VM’s hardware drivers.
- Try using a different I/O scheduler for the VM.
3. The hard disk is showing as “unknown” in the VM
- Ensure that the hard disk is formatted with a file system supported by the VM (e.g., ext4, NTFS).
- Recreate the partition table on the disk and format it again.
- Attach the hard disk to a different VM and try accessing it.
4. The hard disk is not accessible after adding it to the VM
- Check if the disk permissions are configured correctly.
- Restart both the VM and the Proxmox host.
- Mount the disk manually using the “mount” command.
5. The hard disk is not showing up in the Proxmox web interface
- Check if the Proxmox host is running the latest version.
- Clear the browser cache and refresh the web interface.
- Try using a different web browser.
6. The hard disk is read-only in the VM
- Check if the disk permissions are set to read-only.
- Use the “chmod” command to change the disk permissions.
- Attach the disk to a different VM and try accessing it.
7. The hard disk is causing the VM to crash
- Check if the disk is corrupted or damaged.
- Run a SMART test on the disk to identify any issues.

---|---|
Hotplug | 1 |
Save the file and restart the VM. The hard disk should now be recognized.
Best Practices
To ensure optimal performance and reliability when adding a whole hard drive to a Proxmox VM, adhere to the following best practices:
1. Select an appropriate drive
Choose a hard drive that meets the performance and capacity requirements of the VM. Consider factors such as disk type (HDD, SSD), speed (RPM, IOPS), and size.
2. Verify hardware compatibility
Confirm that the hard drive is compatible with the VM host and the guest OS. Refer to the hardware documentation and guest OS specifications.
3. Use a dedicated drive for VMs
Avoid using the same drive for both the VM host and the guests. Dedicate a separate drive to VMs to optimize performance and prevent potential conflicts.
4. Partition and format the drive
Partition the drive into appropriate partitions and format them using a filesystem suitable for the guest OS. Common filesystems include ext4, XFS, and NTFS.
5. Create a VM storage
Add the drive to Proxmox using the “Create Storage” option. Select the drive, choose a storage type (raw or LVM), and assign a name to the storage.
6. Attach the storage to the VM
In the VM’s configuration, go to the “Hardware” tab and add a new “Disk” device. Select the created storage and choose a bus controller type (e.g., virtio, SCSI).
7. Boot the VM from the new drive
Set the boot order in the VM’s configuration to prioritize the new drive. This ensures that the guest OS boots from the added hard drive.
8. Mount the drive in the guest OS
Once the VM has booted, mount the new drive within the guest OS. This may involve creating mount points, formatting the filesystem, or installing drivers.
9. Optimize disk performance (Optional)
Consider implementing performance optimizations such as enabling TRIM for SSDs, using a hardware RAID controller, or adjusting filesystem mount options.
10. Monitor disk usage and performance
Regularly monitor disk usage and performance metrics to ensure optimal resource utilization. Use tools such as Proxmox’s monitoring capabilities, guest OS utilities, or third-party software.
