X-Raid is it for me?

X-Raid is it for me?

Hi.

iam a proud owner of a ReadyNAS NVX BE. I have been running Raid 0 I believe with no redundancy but now im getting a few errors from one of my disks. Its has been running fine for atleast 3 years. But now im more interested in securing my data if a disk failure occurs.

I have been looking a X-Raid. It seems like a good choice.

I have a question:
If my 1st disk is a 1TB can I then add a 500GB disk?

Yes, it is.

You would need to backup your data, do a factory default, open RAIDar, click setup during the 10 minute window choose X-RAID2 and confirm your choice.

No. It is eX-pandable-RAID not shrinkable RAID.

Thank you mdgm.


What if my first disk is a 1TB and my secound disk is a 2TB. Whould that work. And how much storage (in GB) would I have if this ware the scenario?

Aha.

So it would be stupid to add a 2TB disk if the first disk is a 1TB. I would not be able to utilize the remaning storage on the 2nd 2TB disk.

AM I right?

Re: X-Raid is it for me?

You would need to add two 2TB disks to utilise the extra space.

Can only expand when redundant space can be added.

X-raid2 does raid5 and raid1 by default.
If you have 2 disks having the same capacity (or the second having a superior capacity) it will do raid1 equivalent to the space of the smallest disk, leaving some space unused in the higher capacity disk.
If you add another disk, the raid1 will be transformed to raid5 with 3disks and x-raid2 will add another layer which would be raid1 on top of that.

Re: X-Raid is it for me?

Hi guys,

this sounds interesting. Right now, I have two 1 TB HDDs in my ReadyNAS 102. When I want to expand, lets say to 2x4 TB, how do I do it best?
Removing 1 TB and adding one 4 TB HDD really sounds like Expansion, so it should work? When rebuilding is done, I add the second 4 TB HDD?

Or do I have to copy all data to my Computer, shut down the NAS, add the new drives and copy my data back on the NAS?

Thanks,
Chris4711

Re: X-Raid is it for me?

If you have 2x1TB and want to go to 2x4TB, then you
(a) remove one 1TB drive and replace it with a 4 TB drive (with the NAS running)
(b) wait for the NAS to resync
(c) remove the second 1 TB drive, and replace it with the second 4 TB drive (again with the NAS running)
(d) The volume then expands to 4 TB.

During this process the data is accessible, though the NAS will be somewhat slower then usual.

It's always a good idea to have a backup, especially when you are manipulating disks.

Thanks, StephenB!

So it's just a false number displayed an not the real usage on the HDD 🙂
