In the near future I plan on changing motherboard and cpu as the current one isn’t doing so good these days but I will be using the same hard drives apart from adding 1 new one and removing a currently unused drive now am going to be able to just change this and sort out a few settings then get all my data or am I going to have to take all the data off the nas then put all back on again.

From my understanding with this type of hardware upgrade within unRAID there's no need to take data off the drives. It would be important to know how the drives are assigned although unRAID v5.0 keeps track of drive assignments by drive serial number.

 

This type of upgrade is very straightforward. Just to verify, you're currently running unRAID and just upgrading mobo and cpu (and chances are memory,too), right?

Hi apologies for not giving enough info.

i am currently running unraid server version 5.0 plus license I have 6 drives Installed 5 for data 1 for cache no parity drive ye I know it not recommended not to have a parity drive. The only things that are changing is the motherboard and cpu everything else will remain the same. The reason for this is the mb is getting a little old the Ethernet doesn't work properly anymore it does not do gigabit anymore and sometimes the the board just fails to boot for no reason.

You should be fine just swapping out the board and cpu. Good luck!

Not only will it be trivial -- i.e. just connect everything to the new motherboard and boot -- but it doesn't even matter whether you're currently running v4.7 or v5.  Normally you'd have to be very cautious with v4.7, since it doesn't track drive assignments by serial number, as v5 does.    But without a parity drive, there's no risk.

 

If you're not running v5, however, I'd go ahead and do the upgrade BEFORE you switch hardware.

Ok good but I know v5 tracks the hard drives and I want to change one of the drives the drive is currently unused it is in the share but there is no information on it so how would I change it.

so you want to remove one of the 5 data drives and it is completely empty.

 

i know exactly how to do this with parity, but w/o it will be one of two ways

 

1. stop array, un-assign empty drive, start array. normally it will scream about a missing disk, but without a parity it might not. if it doesnt, you're good. if it does, stop the array, re-assign it, and proceed to method #2.

 

2. stop the array, screen shot or picture or write down current drive assignments. click Utilities>New Config. confirm this action and then re-assign all your drives (incl cache) but NOT the drive you wanted to remove. now start the array, voila.

 

cheers,

Thanks for the help I will give this a try as soon as i get my new hardware which is in about 2 or 3 weeks and I will let you know how it went.
