Failed USB

I have a USB drive that failed. I do have a backup, but it's UNRAID 6.1.9 that I tried to upgrade but now it won't boot.  If I installed the latest UNRAID OS on a new USB drive, and got the server booted up, can I assign the existing hard drives into slots without losing their data?  I've assigned the Parity drive without starting the array and there's a warning that says "All existing data on this device will be OVERWRITTEN when array is started."  

 

Is there a way to avoid this or am I ok to assign all the data drives, start the array and then let the array re-build the parity drive?

 

I appreciate any response!  Thank you!

If you're absolutely certain about the drive assignments then it will be fine. If there is any doubt don't assign parity. 

 

Your screenshot shows only 2 disks. Is that all you have?

Thank you for your quick response.  There's actually 7 drives including Parity plus a cache drive.  I am certain they're all assigned correctly, so I went ahead and started the array.  I selected "Parity is already valid" and it seems to have worked.  Now I just need to re-install docker containers, which is fine.  Thank you for your help!

Before you get your containers all sorted, I'd recommend finishing the reiserfs to xfs migration that you seem to have started. You have plenty of free space, so now is the time to reorganize, before you start committing more data to the array.

Thank you for that tip!  I'll do that.  Out of curiosity, what is the advantage to xfs over reiserfs or btrfs?  And maybe a dumb question, but I'm sure it's advisable to have all the disks on the array using the same file system, right?

advantage to xfs

anecdotally, it is the most stable

Dead filesystem.  No further enhancements / bug fixes etc will ever happen

Doesn't affect anything actually.  But reiser is not recommended to have at all.
