Hello everyone. In this video, I will
show you how to recover data from an
SHR2 or SHR Synology hybrid RAID array
on a Synology DS418 play NAS in a
Windows 11 environment. We will look at
various data loss scenarios including
accidental deletion of files or folders,
volume formatting, and storage structure
corruption. You will learn what to do in
case of NAS hardware failure or the
failure of one or more drives and how to
access information if the RAID array
becomes inaccessible and network folders
no longer appear. Additionally, we will
demonstrate a data recovery scenario
from a virtual LUN created in DSM. This
material will be useful for IT
professionals and Synology NAS users who
configure RAID arrays, manage LUNs and
network directories, or use disk space
for deploying virtual machines, server
applications, and databases.
The Synology DS418 Play is a
networkattattached storage device that
provides centralized data storage,
document and media sharing, and secure
backups of important information.
The device supports up to four hard
drives in SHR, SHR2, as well as classic
RAID zero, 1, 5, 6, and 10
configurations, allowing for an optimal
balance of performance, storage
capacity, and data protection. Key
features of the DS418 Play include 2
gigabit Ethernet ports for fast local
network access, support for SMB/CIFS,
AFP, NFS, and FTP protocols for
compatibility with Windows, Mac OS, and
Linux. ISCSI function for connecting to
servers in virtual environments.
Hardware accelerated video transcoding
and multimedia handling. Centralized
data backup via Synology services.
Management is performed through the
intuitive disk station manager web
interface which allows for drive users
and service administration.
The device ensures automatic backup and
synchronization with remote servers
guaranteeing secure storage and access.
To connect to the Synology DS418 Play in
Windows 11, the NAS and the computer
must be on the same local network.
First, download and install the Synology
Assistant Utility on your computer. Once
launched, the program will automatically
scan the network and detect connected
NAS devices. If your device doesn't
appear, open the preferences menu in the
top right corner and enable allow
compatibility with devices that do not
support password encryption to find
older or specific NAS models. After the
scan is complete, select the desired NAS
and click connect. The program will open
the DSM web interface where you can
manage storage, create or mount volumes,
manage users, and configure ISCSI LNS.
If you already know the NAS IP address,
you can connect directly by any browser
by entering the address and logging in
with your account.
To create an SHR2 array, open DSM. Go to
the main menu and launch storage
manager. This section has three main
tabs. Overview, storage, and HDD/ SSD,
where you can view the system status,
pool/v volume settings, and drive
information.
The overview tab shows the NAS layout
with installed drives, their current
status, and detailed info like model,
capacity, and health. The HDD/SSD
tab provides advanced information
including smart parameters, temperature,
event logs, and diagnostic tests. Before
creating SHR2, you must create a storage
pool. Go to the storage tab and click
create to launch the storage creation
wizard. In the wizard, click start and
in the next step, select the RAID type
SHR2.
Next, check the required drives in the
selected drives field and specify the
capacity to be used in the allocate
volume capacity parameter. Choose the
file system and confirm the settings by
clicking apply. The system will begin
creating the storage pool and volume.
You can monitor the progress in the
storage manager. Once the storage is set
up, you can use it for data. To do this,
create at least one shared folder. In
the DSM homepage, open File Station. If
no folders exist, the system will prompt
you to launch the shared folder creation
wizard. Enter the folder name, set up
access permissions for users or groups,
and click finish.
Now you can start writing data. To
upload files, use the upload tab or
simply drag folders from Windows
directly into the shared folder.
Once you have successfully created your
network file storage, you can
additionally create a LUN within an
existing volume. In DSM7, this is done
through the SAN manager section which is
available in the main menu. This is
where you create and manage ISCSI LUNs,
configure connection targets, and work
with block storage. To create a new LUN,
open SAND manager from the main menu. Go
to the LUN tab and click create. In the
window that appears, specify the LUN
name, set its location, and set the size
and space allocation type.
You can also configure permissions for
hosts and initiators that will be
allowed to access the LUN. After
confirming the settings, the system will
create a new LN ready for use.
A target for the LUN is created
automatically during this procedure.
After creating a LN in DSM, it must be
connected in Windows 11 to appear as a
separate logical drive in the system. IC
scuzzi clients are used for this
purpose. In this case, the connection
will be established using the built-in
Windows tool SCSI initiator which allows
you to connect to the ice scuzzi target
and mount the LUN for further data
operations.
In Windows 11, open search and type is
IC SCSI initiator. Then launch the
utility. Once the program is open, go to
the discovery tab and click discover
portal. In the window that appears,
enter your NAS IP address. Leave the
default port and click okay to confirm.
After that, the target associated with
the previously created LUN will
automatically appear in the targets tab.
Select it and click connect to establish
the connection and make the LN available
in the system.
Next, open the disk management utility
to initialize the virtual LUN disk and
create a partition on it.
Once the setup is complete, the LUN will
be displayed in Windows as a regular
logical drive and you will be able to
write data to it.
In the event of a hardware failure or
firmware crash, if you cannot access the
Synology DS418 play directly or via the
web interface, you can use Hetman RAID
recovery to recover your data. This is a
specialized solution for working with
hardware and software RAID arrays
supporting most common file systems and
RAID levels. The program analyzes the
array's service information, reads
configuration parameters, evaluates the
status of each disk, and reconstructs
the RAID structure. After this, access
to data is granted while maintaining the
directory structure and file integrity,
allowing for highly accurate information
recovery.
Before taking any action, be sure to
record the exact sequence of discs in
the RAID array. Each disc has its
specific place in the data storage and
par calculation structure. Therefore,
changing the connection order may cause
file corruption and break the array
configuration, significantly
complicating the recovery process. To
minimize the risk of data loss, it is
recommended to document the location of
each disc in advance and verify their
connection correctness before starting
the recovery procedure. To do this,
connect the discs to your computer via
SATA ports or use a docking station or
an appropriate adapter. If it is
physically impossible to connect all
discs at once, an alternative option is
to create a full image of the
inaccessible drive and use it for
further analysis and data recovery. Run
Hetman RAID recovery. At startup, the
program will automatically detect all
connected drives, analyze their status,
and attempt to reconstruct the RAID
configuration based on service
information. The main window of the
program will display the found discs and
reconstructed arrays available for
further scanning, structural analysis,
and data recovery.
Select your SHR array and run the fast
scan mode. After the scan is complete,
the contents of the RAID array available
for recovery will be displayed in the
program window.
Mark the necessary files and folders and
click the recovery button in the top
menu. In the next step, specify the
destination for saving the recovered
data and confirm the action by clicking
recovery.
Once the copying process is finished,
click finish. After completing all
recovery stages, the data from the raid
array will be available for use again.
If you need to recover data from SHR1,
follow the same steps.
In this case, we demonstrate a scenario
where two discs in the array have
failed, making automatic structure
detection more difficult. Using RAID
constructor allows you to reconstruct
the configuration manually and prepare
the array for scanning and information
recovery. In this type of NAS, SHR2 is
built so that the beginning of the file
system is located at an offset relative
to the beginning of the physical disk.
In case of partial deletion of service
information or metadata corruption,
automatic detection of this offset might
be impossible. To determine the correct
offset value, use the hex editor. The
analysis should be performed
specifically for the physical disk or
partition containing user data, not for
the system volume. If the exact disk
order in the RAID array is unknown, the
process of finding the marker and
determining the offset must be performed
separately for each disc in the array.
Launch the hex editor by right-clicking
on the desired disc or by using thetrlh
shortcut. In the hex editor window,
click the search icon. Enter the search
marker label one for SHR and SHR2
configurations and click find. The label
one value should be located at the
beginning of a sector indicating the
start of the volume's data area. The
offset parameter is defined as the
sector immediately preceding the sector
with label one and this sector must be
filled with zeros.
This video shows in detail how to
correctly calculate the offset value and
apply it during manual array
reconstruction. To work in RAID
constructor mode, you need to know the
basic parameters of your disk array. The
RAID type, block order, block size, and
bytes per sector set during the array
creation. For SHR2, the following values
are used in most cases. Block order left
synchronous P + Q. Block size 64
kilobyt. Bytes per sector 512.
These parameters must be specified
during the manual reconstruction of the
array in RAID constructor.
After entering the required parameters,
select the discs that make up your SHR
array in the available discs field and
move them to the selected discs field.
following the correct sequence of their
placement in the array. If the exact
order of the discs in the array is
unknown, it can be established through
trial and error. Change the order of the
drives in the selected discs field by
moving them up or down with the arrows
and refresh the reconstruction result
each time. Doubleclick on the required
disc or click change disc offset/s size
icon. In the window that opens, enter
the determined offset value in the
offset field. Change the units from
bytes to sectors and click okay. The
program will automatically convert this
value into bytes. This parameter must be
set for all real discs in the array
except for modeled empty discs. If one
or more discs cannot be connected
physically, use the add empty disc
function which allows you to add a blank
disc to emulate the missing drive. It is
crucial to maintain the exact order of
the discs in the array as any violation
may cause incorrect RAID reconstruction
and make data recovery impossible.
When finished, click the add button in
the bottom right corner to move the
reconstructed array to the main program
window for further scanning and data
recovery.
If a LUN has been deleted and you need
to recover data, you can also use Hetman
RAID recovery. After the SHR2 is
correctly reconstructed in RAID
constructor and scanned and the results
appear on the main screen, you need to
find the directory where the LUN is
stored. The virtual disc is located in
the system folder at CSSI TRG.
This folder is displayed among the found
data in the list of scanned partitions
and contains the LUN file which is
available for further saving and
recovery. To start recovering data from
the LUN, you must first save it as a
separate file. To do this, click
recovery, then select next, choose the
save to hard disk option, and specify
the folder to save the image file. Once
the process is complete, an exact copy
of the LUN will be created as a separate
disk image. This file allows for further
analysis and data recovery independently
of the state of the original RAID array
and without reconnecting the physical
discs. Next, open the main window of the
program and use the mount disk function.
In the list of sources, select raw disc
images. Click next and point to the
saved LUN image file.
After mounting, it will appear as a
separate virtual disc. Perform a scan
and recover the necessary files by
saving them to another medium.
