Hi All,

 

So long story short, I added one too many drives and my power supply popped a drive.

No worries, my parity is pretty good (I assumed) so i'll await the replacement drive to arrive and away we go...

 

Not so easy, apparently

 

My disk layout looks like this:

 

but I'm unable to start the array because it says "Too many wrong and/or missing disks!"

 

So...I'm pretty sure my parity is up to date, but I'm unsure when it last ran due to the reboot. I have files on my cache drive still, so I'm assuming this is why it thinks I have an invalid config??

 

How do I at least get back to starting the array? I figured I could do a "New Config" and assign drives correctly but I'll be a drive short due to one of them dying. New drive will be here tomorrow if it makes any difference!

 

Am running unraid 5.0.6

 

TIA.

Pretty good parity is not good enough for a rebuild.

 

I think the yellow ball on parity means it thinks parity is not valid.

 

Is the data drive really dead? It might be useful if you could get it working in case you can't rebuild.

 

Are you sure you have correctly diagnosed your hardware issues? I don't think an underpowered PS should cause a drive failure. Should you be thinking about replacing your PS also if you think that was the problem?

 

I'm 100% the drive is dead. I left out those details as they're not really relevant but I had some shitty power connector, and it must have shorted out.

 

My Parity drive is always yellow like that though, even when I know the parity is just been checked. I assumed the yellow was becuase I had files on my cache drive, and thus, am unprotected?

 

I just need to be able to start the array with the dead drive missing - and to tell unraid that "what you have is fine. trust it."

But if the parity is not correct I'm boned but I can rebuild the missing data....I just need the array to start!

A Yellow indicator on a disk means the disk is not valid. A yellow indicator on a share means cached data. If the parity has always been yellow then you have never had valid parity. You can try the procedure here: http://lime-technology.com/forum/index.php?topic=30009.0

 

It is unlikely to recover correctly. Google SystemRescueCD. Use the CD to recover the contents of the failed disk.

@dgaschk: I don't think this will work if you look at the picture of his hdd board.

 

@xscott: Maybe you can swap the board with one of an identical drive? Then it might be possible the drive still works.

@dgaschk

gah! This is not good news. IS this 100% true even with the dynamix webgui? The icon does indicate the disk has invalid content

 

@SlrG

This is my last hope. I have three identical drives so I'm thinking swap the board and give it a go. Will try this next week.

 

I've ordered a replacement 3TB that will be here tomorrow...Here's what Im thinking then:

 

Reset unraid config - this'll blow away the invalid parity, and accept the remaining data as true.

Get unraid to working point - just without my failed drive.

Ensure parity is correct.

replace an existing 2TB in the array with the new 3tb.

take board from working 2tb, and transplant onto fried 2tb drive.

 

Does that seem like my best route here? The data is only media so nothing I can't re-rip if the worst happens - if this works i'll transfer the data from the friend drive and we're back in business.
