==Foreword==
At the early 2017, we made a NAS storage solution for Raspberry Pi. Accroding to customers' feedback, we made a series of improvements, like [[X800]], [[X820]], [[X825]] V1.5, [[X825 V2.0]], [[X828]], [[X829]], [[X822]], [[X880]], [[X883]], [[NASPi Lite]], [[NASPi]], etc. From only supporting single hard disk to support dual hard disks, from complicated installation to simple installation, now a new raspberry pi storage kit - [[NASPi Gemini 2.5 ]] (only support 2.5" HDD/SSD) is released. Hope you will like it!
You can refer to 'Gemini' means dual, '2.5' means 2.5-inch SSD/HHD; Click [[GEEKWORM NAS Family]] to know more.
===Update History===
* In December 2022, the NASPi Gemini 2.5 has been updated to a new version, it is the update of X882 V1.3 to X882 V2.0, remove the USB-C port on X882 V1.3, and update DC 5V power in to wide voltage input DC6-18V power in.* The new version completely solve the issue of I/O error.

We found that some newbies always ask strange questions about RAID;
Please note: # NASPi-Gemini 2.5 is a hardware RAID. It supports RAID at the hardware level and does not require any software configuration. This has nothing to do with software.# Although NASPi-Gemini 2.5 also supports hardware RAID, BUT we recommend that you use '''software RAID''', even if which will bring a certain degree of ease of maintenance later on. Software RAID comes from the NAS software you use, such as OMV does not support RAID settings;
==Features==
* Compatible with all Raspberry Pi operating systems <span style="color:red;">(If the OS (such as Home Assistant) does not allow the installation of external scripts, then the software safe shutdown and automatic adjust fan speed functions are not supported;)</span>

===About How to choose SSD/HDD===
* Do not recommend using Samsung hard drives, please use hard drives of other brands.
* We recommend that you use HDD instead of SSD, which will cause less WIFI interference
* Older SSD drives with less efficient flash media may not perform as well as newer drives.
* A microSD card is required for forceing the Raspbian OS to use the HDD/SSD for its "root" partition

=== Raid Setting===
Please read [[Raid Instruction]] firstly. You can freely choose the four RAID modes supported by NASPi Gemini 2.5 by setting the jumper cap. Strongly recommend to use the same brand and capacity HDDs when use RAID Mode.
*'''Warning''' : Please backup your data before setup and switch, otherwise you maybe lost your data.
1. Inert HDDs to X882 shield and fix it.
2. Please connect the X882 to your PC or Raspberry Pi board and keep power on.
3. Switch RAID mode
* Set the switch button to your preferred RAID mode(PM/RAID 0/RAID 1/SPAN) as per the RAID illustration table.
* Press the '''SET''' button for about '''5 seconds''', and release it till the blue LED indicators starts flashing.
* After RAID mode changed, please confirm that the PC can recognize the disk(s) properly and shows the right capacity.
or you can run the fdisk -l command to view the hard drive on raspberry pi OS when you connect X882 to raspberry pi board:
fdisk -l
You can found two hard drives if you select 'clear raid mode'(this is PM model)
or
You found only one hard drive if you select the RAID0/RAID1 model
4. Set CLEAR RAID mode (PM, factory default setup)
* Press the SET button for about 5 seconds then and release it till blue LED indicators starts flashing.
* After above processes, the setup for CLEAR RAID is done.
[NOTE] Once you set the RAID mode successfully, you need to partition&format&mount the hdd/ssd, so that it can be recognized by your Raspberry Pi OS. please refer to [[How to View/Partition/Format/Mount HDD/SSD]]

==FAQ==
<span style="color:red;font-weight:bold">Q1: Why only one SSD/HDD is recognized?</span> A: You found only SSD/HDD if you select the RAID0/RAID1 mode. Please '''exit the RAID mode''' and check again after '''entering the PM mode(clear raid mode)'''. More details please refer to '''Set CLEAR RAID mode''' of [[NASPi_Gemini_2.5#How_to_configure_RAID|How to configure RAID]] <span class="tb_red_bold">Q2: What to do if HDD/SSD is not recognized?</span>
A: Please refer to [[How to View/Partition/Format/Mount HDD/SSD]]
Q2Q3: What is the thickness of a 2.5" HDD/SSD that can be accommodated for NASPi Gemini 2.5?
A: NASPi Gemini 2.5 support Max <span style="color:red;">16mm</span> thickness 2.5" HDD/SSD; The thickness of 2.5" HDD/SSD on the market is generally 7mm, 9.5mm, 12.5 and 15mm,so you can choose the SSD/HDD according to your requirement.
Q3Q4: Does raid inside of openmediavault function with NASPi-Gemini 2.5?
A: NASPi-Gemini 2.5 support hardware RAID mode, please refer to above Raid_Setting, or you can set it to PM mode then let openmediavault control RAID setting.
Q4Q5: What are the HDDs requirement when use RAID mode?
A: Strongly recommend to use the same brand and capacity HDDs when use RAID Mode.
Q5Q6: What to do if meet I/O error?
A: First please check if you use the USB Type-C power adapter, if yes, please change to use DC power adapter topower via DC jack of X882 to test. The USB Type-C PSU maybe not enough to power the dual HDD/SSD.
Q7: Why only one SSD/HHD can be recognized?
A: You choose the RAID1 mode, because it is a hardware RAID, so OS recognize only one HDD/SDD.
Q8: How to know if there will be HDD errors?
A: If there is HDD error, there will be red led for the red marked part LED. [[File:Hdd.png|thumb|none|HDD error]]
Q9: RAID issue with OMV.
A: The RAID mode is not tested with OMV OS. The OMV also supports software RAID, you can set the X882 to PM mode and test the software RAID of OMV.
If you want to test the hardware RAID of X882, it can be connectted to WINDOWS PC for testing.
Q10: How to replace a bad HDD?
First of all, it depends on whether you use '''software RAID''' or '''hardware RAID'''. If you use software RAID, there will be corresponding functional modules in the NAS software to assist you in replacing the hard drive. After the HDD replacement is completed, the NAS software will automatically synchronize the data to the new hard drive.
If you use '''hardware RAID''', you can refer to the following steps:
# '''Confirm the faulty hard disk''': If the HHD1 or HDD2 LED lights up red, it means that the HDD feedback S.M.A.R.T read error, it is recommended to replace it
# '''Back up important data''': It is recommended to connect to a Windows computer and back up important files directly through COPY.
# '''Purchase a new hard drive''': To ensure compatibility and performance consistency, it is recommended to purchase a hard drive of the same model and capacity as the original hard drive.
# '''Shut down the NAS system''': to avoid data corruption or other unexpected situations during the replacement process
# '''Start the NAS system''': After startup, the RAID controller will automatically detect the new hard drive and start the data synchronization and reconstruction process. This process may take some time, depending on the size of the
hard drive and the load on the system.
PS: Although GEMINI also supports hardware RAID, we recommend that you use software RAID, which will bring certain convenience to later maintenance. The function of software RAID comes from the NAS software you use such as OMV.
