So I discovered today while migrating to new hardware this evening that I did not jumper the EARS. The system is working fine, but how do I go about adding a jumper to these drives and maintaining my data? Any thoughts?

 

 

Thank you,

Read through the link thread, it should give you everything you need http://lime-technology.com/forum/index.php?topic=5384.0

Wow... that is one hell of a thread 

 

Well I decided to pull the 2TB out and replace it with my standby for the time being. I plugged it into my older unRAID server with a jumper on the 7-8pins and I can't even get it to boot!! Back to reading through that thread to see what it is I have to do...

Ya a lot of folks including myself have done this. It's fairly simple, especially since it is not in your array anymore. I would put the jumper on and run a preclear. Once complete assign it to your array, stop the array and reboot. Then look at the system log and see if you get errors when unRAID is attempting to mount the drive. If you do not get errors than you are good to go.

Problem is it won't boot and this seems to be common for a EARS that has been formatted without the jumper and assigned in the array. I guess the next option is to either try a low level format or RMA the drives...

I did 3 things for mine.

1. I used a command to clear the initial portion of the drive. It is somewhere in that thread

2. Precleared with the jumper off.

3. Precleared with the jumper on.

 

After that I was good to go and the drive is in the pool as we speak. I can not say it will work for all, but did for me.

The system is working fine,

 

You could (should) have left well enough alone if the server was performing fine for you. The jumper missing only means you might cause the drive to read or write an extra sector as it works, meaning it would perform a little slower than it's full potential. I bet if you hadn't bother to even look at them you would have continued on blissfully unaware of having an "issue".

Well I have been having write issues to my drives and I believe it might be caused by these drives. I migrated to completely new hardware thinking that could be the reason why my server would hang when trying to write to it. But I discovered that I still had the write issue. I have now replaced both EARS drives that didn't have jumpers and rebuilding now. Hopefully this will get my server working again.

The jumper just tells the drive to do a +1 to the sector number. If the OS tells the drive to write the data to sector 125 it really writes it to sector 126. Take the jumper off and it just writes to sector 125. The drive just needs the jumper or no jumper when you first create the file system. There is no reason the jumper missing should cause file writing errors.

 

Now, that you posted this, the problem of not getting the other computer to boot makes a little more sense. That is pointing to a hardware issue, assuming the flash drive functions. Could be a bad drive that has now gone so bad it's completely messing up the system.
