I'm stumped, not sure if others have this problem.

1. Installed a new M1015 card and flashed it.

2. UnRaid recognised it

3. Added 2x disks to the array

4. Carried out Preclear on both the disks successfully

5. Assigned one of the available disks to an Unassigned Slot, it is recognized and a blue ball comes on (see screen shot attached)

6. Click on checkbox "Yes, I want to do this" for "Start will record the new disk information and bring the expanded array on-line. All new..."

7. Click on 'Start', the message at the bottom goes "Spinning up all drives... restarting SMB"

8. Goes back to the same screen as (6) above... and not presented with a 'Format' option

 

If I click back to Unassigned, I am able to start the array successfully (without the 2x new disks obviously).

 

Please help or direct me to a prior post.

 

Thanks. cliewmc

Found this answer from this post: http://lime-technology.com/forum/index.php?topic=29315.0

 

It basically requires to boot into 'Safe Mode' - seems the plugins were caused the problem. I have done so, and now able to 'clear' the new disk(s).

 

I just wonder if the pre-clear flag is still in place, otherwise it will be a very long wait to provision the 2x new disks. I have rebooted the unRaid a couple of times. If you can kindly answer my question, I shall cancel the 'clear' and 'pre-clear' the disks again to save time.

To my last question, the Clearing in Safe Mode, took about 8 hrs (3TB), followed by Formatting which took 5 mins. I have now managed to include the new disk in the array. So that answered my question that the Pre-clear signature was in place?

 

Now to proceed to the next and final disk to finish the operation. Regards. cliewmc

unRAID will not clear a disk that has a valid signature.

Thanks dgaschk for the response, the 2nd disk took about 6-7 hrs to clear, and 5 mins to format. Both the disks are now in the array, and all green balls!!!

 

Interesting that you said that the signature is no longer valid, and clearing will not start. It took only 6-8 hours to get a disk online, does it mean that pre-clear is no longer efficient? It took 24 hrs to pre-clear.

 

Based on this experience, reading up in the forum, and your response, they have provided me with more knowledge about unRaid. Happy for you to close the question. Thanks for the support. cliewmc

The timings for clearing a disk are consistent with the times the pre-clear script takes.

 

The pre-clear script does a pre-read;  then it clears the drive;  then it does a post-read (which takes about as long as the first two steps combined).    UnRAID just does the clearing.    Using the pre-clear script is a more thorough test of the drive -- and has the added advantage letting you add a drive that's already cleared.
