Volume Inactive
QNAP Volume Inactive (NAS): storage pool or volume inactive
Risk level
High
Professional inspection is recommended.
Urgency
Immediate
Quick answer
On a QNAP NAS running QTS, when volumes and storage pools change to Inactive and their RAID group status changes to Error, several disks have been removed or disconnected from the RAID group and all data on affected volumes and LUNs becomes inaccessible.
Safety first
Stop and check this first
- Ensure that each disk is reinserted into its original drive bay; RAID recovery only helps when disks are temporarily disconnected and reconnected, not in the event of disk failure.
Safe checks you can perform
- Ensure every disconnected disk is reinserted into its original drive bay
- Inspect the Inactive pool or volume and Error RAID group in QTS
- Check whether the System Status LED is solid red on the NAS
Leave these tasks to a qualified professional
- Do not attempt this professional task: Reconnect all disconnected disks into their original bays and run Recover RAID
- Do not attempt this professional task: Diagnose SATA connector or multi-drive hardware failure when Recover RAID cannot be used
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Reconnect all disconnected disks into their original bays and run Recover RAID
What they doThe technician reinserts each disconnected disk into its original drive bay, navigates to Storage & Snapshots > Storage > Storage/Snapshots, selects the Inactive storage pool or single static volume, clicks Manage, selects the RAID group with the status Error, and clicks Manage > Recover RAID.
They must show youeach disk seated in its original bay and QTS starting to rebuild the RAID group after clicking Manage > Recover RAID.
In writingoriginal bay assignments verified, RAID group recovered from Error status, and restored access to volumes and LUNs.
Diagnose SATA connector or multi-drive hardware failure when Recover RAID cannot be used
What they doIf reconnected disks still fail detection or show solid red HDD LEDs from read/write errors, the technician inspects the SATA connector/backplane and escalates for data recovery or backup restoration without formatting the array.
They must show youthe drive detection status in QTS and the hardware fault preventing standard RAID recovery.
In writingSATA connector and drive health findings, reason Recover RAID is inapplicable, and next recovery step.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Ensure every disconnected disk is reinserted into its original drive bay
- Who:
- you, inspecting the drive bays on the QNAP NAS with an Inactive volume.
- How:
- check whether multiple drive trays were pulled out or unlatched, and reconnect all disconnected disks into their exact original drive bays.
- Result that matters:
- restore physical detection of all member disks in their original bay positions.
- If all member disks are detected again without solid red HDD error LEDs:
- proceed to Storage & Snapshots in QTS.
- If drives have physical hardware failure and cannot be read:
- stop because QTS RAID recovery does not help in the event of disk failure.
- Evidence to keep:
- bay mapping confirming each disk was reinserted into its original drive bay.

Inspect the Inactive pool or volume and Error RAID group in QTS
- Who:
- you, logged in to QTS after reconnecting the disconnected member disks.
- How:
- go to Storage & Snapshots > Storage > Storage/Snapshots, select the storage pool or single static volume with the status Inactive, and click Manage.
- Result that matters:
- open the Storage Pool Management or Volume Management window and locate the RAID group with the status Error.
- If the RAID group with status Error is visible and all reconnected disks are online:
- proceed with Recover RAID.
- If drives remain missing due to a SATA connector failure or drive fault:
- arrange hardware service before altering the array.
- Evidence to keep:
- Storage Pool or Volume Management window showing the Inactive pool and Error RAID group.

Check whether the System Status LED is solid red on the NAS
- Who:
- you, checking the QNAP NAS front panel indicators alongside QTS logs.
- How:
- observe whether the System Status LED is solid red and check QTS to see if it reflects an invalid hard drive, disk read/write access error, bad sector, or degraded read-only mode.
- Result that matters:
- distinguish a temporary multi-disk disconnection from a physical disk or hardware fault.
- If the event was caused solely by temporary disk disconnection:
- run Manage > Recover RAID.
- If the drives report physical read/write errors or bad sectors:
- contact support without initializing the disks.
- Evidence to keep:
- recorded System Status LED state and QTS system log entry for the storage error.

What it means
The QTS 4.5 guide "Recovering a RAID Group with an Error Status" explains that when several disks are removed or disconnected from a RAID group (due to accidental disk removal or SATA connector failure), the RAID group status changes to Error, all volumes and storage pools using it change to Inactive, and all data on affected volumes and LUNs becomes inaccessible. On the NAS front panel, the System Status LED may light solid red (invalid drive, read/write error, bad sector, or degraded read-only mode). RAID recovery only helps when disks are temporarily disconnected, not in the event of disk failure. An Inactive status alone never proves the drives themselves have failed.
Warnings and stop conditions
- Highsource verified
Ensure that each disk is reinserted into its original drive bay; RAID recovery only helps when disks are temporarily disconnected and reconnected, not in the event of disk failure.

Symptoms and causes
Probable causes · in order
- Accidental removal or temporary disconnection of several RAID disksCommon
Multiple member disks were removed or disconnected from the RAID group at the same time, setting the RAID group to Error and volumes to Inactive.
Evidence: QTS 4.5.x User Guide: Recovering a RAID Group with an Error Status
- SATA connector failure dropping multiple member drivesPossible
A SATA connector failure interrupted communication with several disks in the RAID group, making affected volumes and LUNs inaccessible.
Evidence: QTS 4.5.x User Guide: Recovering a RAID Group with an Error Status
- Actual disk failure across multiple RAID member drivesLess common
Multiple drives suffered hardware read/write failures or fatal errors, a scenario where QTS states that RAID recovery does not help.
