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.
