Hej All,

 

It seems as if I have a faulty disk in my system, it is generation some errors.

 

My question is this:

 

Is there an easy way 2 remove the disk and have unraid write the missing data to the rest of the array, without replacing the disk ?

 

I have more than enough available space in my system, and I'm not gonna replace the faulty disk just now, so I just want to distribute the data evenly onto the rest of the disks in my unraid setup, but how do I do that.?

You can disable the disk, but you'll have to manually copy the data from the emulated disk.

Question, gents....

Does UnBalance work on emulated disks? It was just an odd thought as I read Kaltar's plight?  I think it should? Would that be faster/easier than using - I'm guessing- Midnight Commander and doing it manually?

 

Reason: I used unbalance to move a buncha files from one physical to another physical disk, changing the format from Reiser to XMS - it was pretty easy, but I didn't have issues with the disks or anything being emulated - just different formats. I thought it might help Kaltar out. I don't remember if you can move stuff to specific locations, but if you just wanted it reallocated to what disks you have, you could just move everything elsewhere and then decommission the emulated disk and remove the physical.

 

Will that work?

Almost sure it doesn't.

That's too bad. I was going to see if it stated outright that it does or not. It would have made this pretty effortless and a neat trick, to boot. 

Okay, I'm in the process of copying data from the faulty disk to a new disk, and I think i'm getting som really slow speeds.

Is it normal speeds i'm seeing in the pictures ?

 

I'm copying from disk 4 to disk 7.

 

I can't help but think that something is terrible wrong in my unraid setup, the disks have all been tested using disk speed plugin a while back, and there i got teses speeds.

Looks about right, it should be a little faster with turbo write enable.

Kaltar, how did it come out?

 

Also, considering that you are copying an emulated disk...yeah. It's slow. Beats the heck out of re-ripping content or chasing backups. Not saying you shouldn't have backups, mind you. I think the reason it is slow is because it is having to reconstruct the file image on the fly, copy it to a new target volume, recalculate parity on the new moved-to position. So, yeah, you're thrashing the parity drive to death.

Well so far it is not even moving frm an emulated disk, i'm acutally copying from the faulty disk.

 

The disk isn't totally crashed, and to be honest, i'm not even sure it IS faulty.

 

It showed up with 64 write errors, and when I try to run an extended smart test, it fails.

The disk has som Raw read error rate fails, so I guess it is time to RMA it, if just I can find out where I bought it.

There's a read failure during the extended SMART test so it's a disk problem.

 

When I said the speeds are normal before I was aware you were copying from the actual disk.
