Replacing a Harddrive with a larger one? Help

Featured Replies

UNRAID 5B12A

 

 

I had a drive (2tb) which was running about 92 percent full so I opted to replace it with a 3TB

 

I shut the system down and replaced the drive

Rebooted and assigned the new drive in the place of the old drive location

I started the array and it displays rebuilding (at the bottom of the menu) Ball is orange.

 

After several (6)hours its now displays 45percent completed

 

1. Is it normal for it to say unformatted while its doing this rebuild?

 

2.  I thought the hd would be available during the rebuild? - it does not show in windows explorer but all the other drives do.

 

Any help would is appreciated

Joe

Hello,

 

Did you per clear the drive before adding to array? If not that would probably explain the long wait.

The fysical harddisk will NOT be accessable during buildup, the data that 'was' on it (or better, was on the old drive), should. That data is being 'recreated' using the other disks + parity, so you can access it like it was never gone, and in the meantime it is fysically recreated that way on the new disk as well. Once rebuilt, the disk itself will be accessable again.

Replacement drives are not cleared because they are written completely with appropriate data.

The drive and its contents should be available during the rebuild. Report when the rebuild is complete if the data does not appear. DO NOT press format.

dgaschk,

Added new larger drive - WDC_WD30EZRX-

file type system is showing unknown

 

The rebuild has completed and all balls are green, but it still says unformatted and the drive is not showing up in explorer.

I had precleared the drive just to ensure it was in good shape.

 

I stopped and restarted the array - no change

smart status passed - short test

Did a system reboot -  no change

 

log:

Sep 14 08:16:16 Tower39 emhttp: shcmd (28): rmdir /mnt/disk4

-------------------------------------UPDATE ------------------------------

 

I decided to go back to before i added the new drive.

 

The system is now up and running with the original drives, all is green and all looks normal. I am doing a fresh parity check and I can still access everything fine.

 

Once it is completes, and with no errors, i will shut the system down and replace my 2tbwd - (md4) with a new pre-cleared wd3tb drive.

 

This time when it comes back on line, if i see unformatted on the new drive, i will select format - to format any unformatted drives --- (which would only be the new drive)

 

Then i presume, i can initiate a rebuild once the correct file system is formatted on to it.

 

This should start rebuilding the new drive with data that was on the removed drive.

 

Is my thinking making any sense?

 

Thanks for any inputs

Joe

NO! Stop! DO NOT FORMAT ANY DRIVES UNLESS YOU WISH TO ERASE THE CONTENTS OF THAT SLOT.

 

Unraid does not work the way that you are thinking, it just recreates the contents of the removed drive on the drive that you assign to that slot. If you format that slot, you will lose all the data in that slot. If the contents don't show up after the rebuild, then the rebuild failed in some way, and you must address that failure correctly or you will lose data. I didn't see your syslog attached to any of your posts, I suggest you capture a syslog with the old drive running properly, and another syslog after trying to rebuild on the 3TB, and post them both.

jonathanm,

 

Ok, Big thanks!! for the info.

 

Unraid is looking at the slot and if i did a format than i would loose data in that slot... got it!!

 

 

---While i am waiting for the parity to be completed on the main unraid:

 

TEST SYSTEM:

I took the new 3tb drive and installed it on another unraid test system and performed a make reiserfs to put a unraid format on the new drive, then tried it in the array and it picked it  up perfectly.

 

Now  the test system sees the new empty drive with the proper format, i  am thinking it should work on the main working Unraid system.

------------------------------------

 

MAIN SYSTEM:

 

1. After parity check is done on my main working unraid, i will shut it down gracefully.

2. Remove the older 2tb drive and install the new 3tb drive (i already have a 3tb as parity).

3. Reboot and wait for unraid to become available.

 

4. I should see 1 drive missing (slot4)old 2tb.

 

5. I will assign the new 3tb drive to that slot.

 

6. Once the new drive is installed(assigned), the drive should in a short period of time, display a normal reiserfs fs and probably an orangeball during the rebuild. There should be no un-formatted drives displaying!

 

7. If i now start the array, it should begin a rebuild of the drive and populate with data that existed in that slot.

 

8. I realize this will take a while, but I believe i should have access to that slot (drive data) within 10-15 mins, all while its rebuilding in the background.

 

9. When its all rebuilt, i probably will tell the system to do a parity check....

 

 

 

Hope, i got it straight this time 8)

Joe
