hi all

 

one of my drives in my server is a 1Tb HDD, i would like yo swap this for a 2TB drive which i will buy soon

 

do i just simply swap the drive and let unraid rebuild?

 

or is there any other process?

 

Current Setup:

 

Parity: 2tb

disk1: 1tb

disk2: 1.5tb

disk3: 1.5tb

cache: 500gb

 

thanks

My understanding of this is, yes. You put the new drive in and then in the web interface, select the replacement drive and let it rebuild.

 

I'd wait for confirmation from a more seasoned user though. 

Yes you can simply replace the drive and assuming all the other drives are healthy unraid will rebuild on the new drive. This assumption that all drives are healthy is an important one, I would do a couple steps to confirm the health of the system and the new drive before actually doing the swap.

 

First, I would do a parity check to ensure all your current drives are working well.

Second, I would do at least 1, preferably 3 preclear passes on the brand new drive to make sure it's not going to die an early death.

 

If you are the cautious type, I'd post the syslog after you do the parity check, and smart reports on all the drives including the new drive after it has been precleared, and wait for somebody to give you a second opinion on the health of the system before actually doing the swap.

 

If there is no data on your system that is important, than by all means just swap the drives. It will take a fairly long time to do the preclears and parity check, so if you don't care about the data, I wouldn't waste the time. I'm not being flippant here, some people don't use their array for anything really important, it's just a backup of other data, so spending several days for no reason isn't necessary. Most likely the upgrade will go just fine without all the checking.

Basically,that is it.  Most will suggest running the preclear script on the new drive first, prior to assigning it to the array, just make sure it gets past the first part of the "bathtub curve"  Also, a parity check prior to doing anything will verify the  health of the other drives you will be using to reconstruct the one being replaced.  Save a copy of the "config" folder and a screen-shot of the current drive assignments too... Just in case.

parity check your array first, that should be done periodically.  I had a drive go bad while rebuilding causing the array to loose integrity.

Therefore a parity check should be a a monthly operation and your first operation before adjusting any drives.

 

preclear drive in an empty slot. Make sure it is reliable.

 

After that you can switch the drive.

I would store the removed drive in a safe place for 30-90 days.

 

thank you all

 

will report back when done
