Disaster happened, (hypothetical scenario)


Recommended Posts

Say, thunder struck and fried PSU, motherboard and attached USB sticks. The harddisks however survived this disaster.

 

Can these disks be added to a newly built server, recreating the original disk configuration? What files would I need from the original USB stick?

 

Can all disks be added at once, or should I start with the datadisks, or cache disk and parity disk first?

If you have a copy of your usb stick then you do not need to do anything (but activate it with a new key if you do not have two).. I actually zip my usb drive and mail the zip to my hotmail account every time I change disk stuff.. That way I can allways recreate... I do it more to protect myself from usb failure though.

As long as you have a record of the drive order, it should be no big deal. This scenario really is no different than a motherboard upgrade with a fresh unRAID install...which I have successfully performed.

 

What if I don't know the drive order, but know which is parity and cache drive? I also have a backup of the super.dat file.

Good suggestion!

 

Are there any hidden files on the usb-stick?

I actually backup my flash drive and devices page every day to a server that gets backed up to CrashPlan.  Using the unMenu page, I dont have to pass a username and password in my wget.

 

"c:\Program Files\TeraCopy\teracopy.exe" COPY \\nas\flash t:\unRAID_Backup /OverwriteAll /Close

wget http://nas:8080

xcopy index.html t:\unRAID_Backup\ /y

If you don't know the drive order, assign them all as data drives and the parity will be the unformatted drive.

 

This should work to find the cache drive:

Un-assign the parity drive and start the array. Now determine which one is the cache drive by looking at the contents. Stop the array. Assign cache and parity then start the array.

you do not need drive order on unraid v5 .
