Hello, I was working on an archived video project (approx 15TB). I had an r6 mounted and the footage was all there and available.

Then I unmounted the RAID.  I inadvertently popped open two drive draws, forgetting the RAID was still powered on.

Here's the Promise utility screenshot.

As you may be able to see in the above screenshot, two drives are now "offline" and the RAID is degraded and unmountable.

I'm hoping all the data is still on those drives and I can reconstruct the RAID.

Is there a way to get the RAID back into a happy happy state?

If not, is there any hope for data recovery from a third party or is that folly?

Thank you for your thoughts, time and expertise. Bergen.

Hi Bergen,

can you create a service report in the utility, zip the file and attach it here please ?
It should be possible to restore the RAID drive back to normal but which steps to follow depend on the current exact state and occurrance of events shown in the report.

Kind regards,
Frank

Thank you Frank.

That sounds promising. I'll attach as advised.

ok, in this case it is safe to force both disks 1 & 2 back online, since both were marked dead almost simultaneously.

You can do this using cli by opening a terminal window and type below commands:

promiseutilpro  (this will open the utility in cli)
phydrv  (check that disks 1 & 2 are marked dead)
phydrv -a online -p 1
phydrv -a online -p 2

LEDs should return to blue and logical drive should mount.
check again with command phydrv that both disks 1 & 2 are now marked 'forced online', then close the terminal window.

Please do NOT use this procedure in case of a single disk failure, or if some time passed between 1st and 2nd disk failure.
This will most likely result in corrupted or damaged filesystem and/or files.
If only 1 disk is marked dead due to removal and the array is critical but the drive is not offline then you can simply start a rebuild on the 'dead' disk to get the disk back online.

Awesome. Thanks Frank. I'll give that a go and let you know the result.

Frank, you are a superstar and I salute you. That all worked beautifully and I have my RAID back in a stable state with all the rushes accessible. Bonzo Bro. Bergen.
