What to do if HDD storage is not detected

If your storage server does not show the additional HDD storage, that does not automatically mean the disk is missing. In many setups, only the NVMe boot disk is mounted by default. Additional HDD storage often still needs to be checked and mounted manually.

1) Check with lsblk

First, check which disks the system can actually see:

lsblk -o NAME,SIZE,TYPE,MOUNTPOINTS,FSTYPE

What to look for

• Is only the NVMe boot disk mounted, for example nvme0n1 with partitions such as / or /boot?
• Is an additional HDD shown, for example as vdb, sdb, or similar?
• Does that HDD have no mountpoint?

If the HDD appears in lsblk but is not mounted, that is usually the actual issue: the additional storage exists, but still needs to be mounted.

Then use this guide:

• Format + Mount HDD storage

2) If the HDD does not appear in lsblk

If no additional HDD appears in lsblk, check the dashboard to see whether the disk still needs to be added there.

Dashboard steps

1. Open your storage server details in the dashboard.
2. Go to the Disks section.
3. Check whether an additional HDD is available or can be added.
4. Add the HDD if that option is shown.
5. Wait until the process finishes.
6. Connect again via SSH and run lsblk once more.
7. If the HDD is now visible, mount it afterward.

In the dashboard, open Disks under Service Management (1), then click + Add Hard Disk (2).

In the Add Hard Disk dialog, enter the HDD size in GiB (for example the capacity included with your Storage VPS) and select local-HDD as the storage type, then click Confirm.

If the HDD becomes visible after adding it, then use this guide:

• Format + Mount HDD storage

3) If neither helps

If the HDD is neither visible in lsblk nor available to add in the dashboard, please contact support.

Useful information for the ticket:

• Output of lsblk -o NAME,SIZE,TYPE,MOUNTPOINTS,FSTYPE
• Name or ID of the affected server
• Short note that you already checked the Disks area in the dashboard
