rebuild taking forever

Featured Replies

I'va had a disk that came emulated, since then everything went awall. Now I'm rebuilding, but it shows 0.6% after 12hours on a 6Tb.

Are you saying that you installed a disk into your array and formatted.  Then it ran emulated while it pre-cleared on the fly?

one of my disk came with a red X so it couldn't be used anymore.

I replaced it with a precleared disk, and a second disk became unavailable reporting errors on it.

Now the rebuild as been running for 24h and I'm at 1%

Disk2 is failing so you won't be able to rebuild disk1, maybe old disk1 isn't completely dead and you can still recover some data from it, disk2 looks in very bad shape, not surprising considering it's the infamous ST3000DM001.

So you're saying I should stop the rebuild process?

Sorry I'm not very good with forums, and replies...

It keeps wanting to rebuild the disk1...even though I see my data on it!

  • Community Expert

There's not much point in continuing the rebuild since it will be mostly corrupt, unless old disk1 completely failed you have a better chance of getting that data using it.

Is it possible to have the system skip the data rebuild?

Click on cancel on the main page, next to the start/stop array button.

I did it, but I'm still stuck with the option to sync and a yellow triangle on the first disk. Only option is to keep that one going...

  • Community Expert

After canceling you need to stop the array and unassign the disk, if you want to start it again without rebuilding.

But note that you won't be able to correctly access the data on both disks 1 and 2, since disk2 is failing and the emulated disk1 needs all other disks to be functioning correctly.

So my only option would be to keep rebuilding? Otherwise what would be the best way to gain access to the data?

As for disk2 , try to copy everything you can from it but it looks to be in very bad shape.
