Dear TerraMaster Support Team,

I am experiencing two issues with my TerraMaster F2-424 running TOS 7.

Issue 1: Unable to change user home directory from Volume1 (NVMe) to Volume2 (HDD)
I am trying to back up my desktop computer to the NAS, but the backup software automatically routes to the user's home directory on Volume1. Because Volume1 is a 1TB NVMe drive, it is filling up quickly. I need my user home directory (/homes) to reside on Volume2 (10TB HDD) instead.

I attempted to change the primary volume via Control Panel > Privileges > Shared Folder > Advanced > Restore to, but this option is completely missing from the TOS 7 interface, and homes does not appear in the Shared Folder list. I also tried manually creating the /Volume2/homes directory via SSH, but TOS 7 does not recognize it as a valid shared folder, and the TNAS Desktop App's backup service does not allow selecting this directory.

Issue 2: Asymmetric LACP Network Speeds
My network is configured with Active LACP 802.3ad. I am experiencing inconsistent transfer speeds. When uploading to the NAS, I achieve full 2.5Gbps speed. However, when downloading from the NAS, I am only getting 110 MB/s.

System Information:

Model: TerraMaster F2-424

OS: TOS 7

Volume 1: 1TB NVMe (System/Apps)

Volume 2: 10TB HDD (Data)

Network: Active LACP 802.3ad

Request:

Please provide an official solution to change the default location of user home directories from /Volume1/homes to /Volume2/homes in TOS 7 so it is recognized by the system and backup services.

Please advise on the correct switch-side configuration or TOS settings needed to resolve the asymmetric LACP speed issue.

Thank you for your assistance.

Here are the details and troubleshooting steps regarding your two issues:

Issue 1: Changing User Home Directory to Volume 2

Currently, moving or relocating the User Home directory (homes) to a different volume is not supported in TOS 7. However, this feature request has already been accepted by our product team and is planned for implementation in a future update.

Issue 2: Asymmetric LACP Download Speeds

A download throughput capping around 110–115 MB/s typically points to a 1 Gbps link limitation along the outbound path.

Please check the following:

1. Verify Link Negotiation:

• Go to Control Panel > Network > Network Interface (and check your managed switch port status).

• Ensure that both physical ports in the LACP group are negotiating at 2500 Mbps Full Duplex. If either port or cable drops to 1000 Mbps, outbound traffic hashed to that link will cap at ~110 MB/s.

2. Physical Disk Read Performance:

While upload tests write directly to Volume 1 (NVMe SSD), download tests read from Volume 2 (10TB mechanical HDD). Check if background I/O or non-sequential file operations on the HDD are bottlenecking read throughput to ~110 MB/s.

3. LACP Hash Policy:

Standard 802.3ad LACP balances traffic per stream based on hashing. A single connection cannot exceed the 2.5 Gbps bandwidth of an individual link. Ensure both the switch and TOS are using Layer 2+3 or Layer 3+4 hash policies.

Hope this helps!
