I upgraded my server to new hardware over last couple of days and had everything working fine. All my disks correctly listed and all shares working.

However I had some problems booting from the usb stick about one out of 3 times it would not boot from usb. So i backed it up the usb then formatted it then installed a fresh unraid to test my boot problem. I found problem was caused by my second keyboard causing the rig not to boot from usb for some reason.

 

So after i had sorted that problem i went to put the backup of my usb stick back onto the stick.

It then booted fine and i entered my license key. However none of my disks are assigned anymore except the cache drive.(all my plugins are there) I am not sure which drive was parity etc so am worried i will loose all my data if i make a mistake here.

 

I could take server apart an look at each disk and its serial number as i labelled each disk as i put it in but i would rather not have to do this.

 

Please can anyone help?

 

I am using 6.2 beta21

You must not have restored the flash drive correctly.  The drive assignments are in the config/super.dat file, so make sure the backup has this, and the config folder is fully restored.

Ah thankyou Rob. That file was missing for some reason ,so i have found an old backup with all but one of my disks in it. So i can assign it now but i guess it will then erase it and rebuild from parity?

You should absolutely NEVER use a super.dat that doesn't match your current configuration. Just go without it and assign all your disks again, making very sure you don't assign a data drive to parity. If you are sure parity is current you can check the box before you start to prevent it from rebuilding parity.

Thankyou so much for your help. I found i actually had 2 backups of the usb i made today. One was missing the super.dat and the other one had it. All is back and running....i am sure i will break something else, but then thats half the fun of it, breaking, learning then fixing!!
