What type of file system does the ix2 use with hard drives? For safety, I'd like to know how to recover data from the drives if the ix2 fails. I do not like the idea of relying on some hidden proprietary format that requires the ix2 to be able to retrieve my data in case of failure.
I've looked on Windows and it lists it as some Microsoft RAW format.
I've tried on Linux (Debian) and it says it some sort of RAID file system, but it still can't read it or I don't know how. Its not NTFS, ext2,3,4.
Anyone know how to read the disk formatted by the ix2 from a PC running any operating system?

Its not just the file system on the drive, normally it is the proprietary RAID algorithm built into software or interfaces firmware which makes it nearly impossibe to read RAID-system drives on a PC ( especially if you are only able to connect individual drives out of the set). ( same with e.g. Intel-software RAID and special inbuilt controllers).
So backing up your data is mandatory.

What raid level are you using? If you are using raid 1 it may be possible to mount to a Linux system but can be difficult without advanced skills. This is not in a proprietary format, it is Linux base which is pretty much the opposite of proprietary. The drives are ether in XFS or EX4 depending on firmware.
However, wolliballa is correct. The best thing to do is to make sure you have a true back up system then you shouldn't have much to worry about. Having the data in one location, even in raid, is not a back up. Even an external USB drive setup with copy jobs is a good idea.

It doesn't seem very realistic to say keep a backup. The ix2 may be the backup. RAID mirroring is done to prevent loss of data in event of a failure.
Not being able to read disks in the ix2 outside of the NAS greatly increases the risk to data.
I think that Lenovo should publish information about the disk format so that if someone were technical enough, they could access their data.
In that light, I have been able to come up with a set of commands that has successfully allowed me to read data off the disks. However, during the process, I'm apparently modifying the configuration on the drive. The ix2 unceremoniously crashes (hangs) after placing the drive back in the ix2 and booting.
I currently have a single drive installed as RAID 1.
I booted a PC into Linux. Installed dependent packages and ran the following commands. Some of the parameters vary depending on which device a particular installation decides to assign for the drive. I placed the drive in a USB dock and connected the dock to the PC.
# Defines a logical volume group using the partition and harddrive associated with /dev/sda2.
# Says raid 1, that there are two drives, but its ok if only one drive is given.

Raid is not a file system. The ix2 uses either Linux based XFS if it has firmware 3.x or if it was setup or factory restored with FW 4.x it will have EXT4 and uses a MDADM RAID system. The Raid is setup either in Raid 1 for redundancy in the event of a drive failure Raid 0 for thoughput or no protection for space.
All NAS devices with multiple bays have RAID options. Usually, the most common component to fail on a NAS is a drive. If you only have one in there, taking it out and attaching it to another device will not help.
We do not support or recommend removing a working drive and connecting it to anything device other than an identical unit running the same firmware. Even then it is risky. If you are doing so then you are doing it at your own risk.
When you are adding other drives you need to make sure they are clean without any partition then it should incorporate them into the raid better.
So I assume this was a diskless unit or you would have 2 drives in it. I would recommend running it with 2 identical drives, in raid 1. Then if one fails you can swap out the bad drive and it will rebuild the mirror back to the new drive.
However, that is still not a true back up. If the unit, controllers or something else major happens all data will be lost and you will need data recovery.
Here are links that explain a backup, raid and more:

I have an ix2 ordered diskless. I installed a single blank disk. That disk is the one I'm attempting to read outside of the ix2 and trying to figure out what disk format is being used.
The firmware version is 22.214.171.124716
I have not configured the ix2 to use any RAID configuration nor do I find any option to do so. I'm using whatever default settings it came with.
I've explained the one way I've found so far to be able to read data from the disk outside of the ix2.

If you found a reliable way to move the drive between devices that is up to you, but we do not recommend it or support it. If this is going to hold important data then you really should put in two drives in a raid 1 AND have another device with the data on it, such as the original computer, an external hard drive, or another NAS. Relying on one disk and hoping you can take it to a computer in the event of failure is very risky, if the drive itself dies or a problem when moving it the data will be lost.
FYI, With firmware version is 126.96.36.199716 it will be in EXT4.
We always recommend using 2 drives. If you have installed two new drives in an ix2-dl, it will automatically create a RAID array with the new drives.

I just got off the phone with Lenovo support with the same question. ix2 won't boot with either hard drives. I need data from the drives so attempted to access from a linux environment, but they do not use standard file formating. The tech told me if I needed the files it would have to be done through data recovery, because there was no way to access from another device. I am trying one last method now before paying hundreds in data recovery, and will report if it works.
