majorcode,

All of the drives in any one storage pool must be uniform.

A good way to ensure this is to just buy all of the exact same drives.

The problem isn't with the drives, but rather with the procedure used to upgrade.

 

The PX4-400D reserves a small 22GB partition on each drive to store system data and programmes. This is mounted under /mnt/system and it is mirrored on multiple drives.

 

If you replace all the drives at once the partition will be totally gone and thus the device will fail to boot.

 

You have 2 options:

1) do a full reset

2) re-install back the original 2TB drives (assuming you have not erased them), delete all shares drives. This will clean the device but will not delete the system partition. Once done replace the drives one at a time and each time reboot. This will give the PX4-400D the opportunity to re-create the system mirror on each new drive. It is a cautios approach, you may replace even 2 at a time, but I recommend one to be sure there will be at least a good mirror partition copy left.

 

Once done create your new RAID 5 drive and volume.

Hi Gus_Lenovo,

 

Since the unit is arriving with 4TB (Which might be Server class Hard disk). Whereas in local market here I can only able to get NAS HDD  WD Red 4TB  PN#WD40EFRX. Will it work Server Class HD + NAS HDD or I have to remove Server class hard disk?

 

Kindly advise

 

Thanks

majorcode,

I'm not certain which device you're speaking of, but if you select your model NAS from this list:
https://lenovo-na-en.custhelp.com/

And navigate through the OS option, you should be able to find a list of approved drives.

Just below the table of approved drives, you will see the notification listed below:

IMPORTANT: All disks within a single storage pool must meet the following requirements:

Same manufacturer
Same rotational speed
Same capacity

Mixed disk configurations may result in unpredictable device behavior and will not be supported. If you need technical assistance, please be prepared to backup your data and remove any unsupported drives or configurations.

------------------------------------------

The drives you are listing do not appear to meet these requirements.

If you Google the manufacturers part number, you will find returns describing drive specs.

Does anyone know where the lists of qualified drives for all of the PX series have gone?  We hava a bunch of these devies still installed, and need to replace some drives.  None of the links in this forum post are good any more.

 

Thanks,

Dino
