@GatekeeperZA did you ever try this card?

That makes sense yes, I don't have an option for that on the GUI however, do I need to modify the VM XML in order to do that?

Sorry forgot to add, the other possibility would be to install ddrescue directly on Unraid then I could just do the image from Unraid terminal onto an Unraid share, not 100% sure if it's possible to install ddrescue on Unraid though?

Hi, I have a synology drive from a crashed synology machine and I need to get data off the drive. I first used an external USB dock and was able to access the drive from a VM on Unraid and use ddrescue to make an image of the drive. My USB dock is however a bit flakey and keeps turning off and stopping the process plus is very slow so I then plugged the drive into my Unraid machine in the hopes that I could access it from a VM that way. Here however is my issue, is it possible to give a VM access to an unmounted drive?

Sorry no I didn't read the page right. I tried the new config but it still kept saying it can't start so I took the plunge and put my 2 new drives as parity and drive 1 and started then mounted other drives with mount plugin and first copied data off 1 drive, unmounted and added to array then next etc and as I went removed the other drives that had smart issues so am now up and running with just healthy drives. Whatever data was on disk 3 is gone but guessing that with parity having kicked in on disk 4 already disk 3's data was gone regardless so all up and running. Thank you for your help!

I just want to double check, if I go Tools ->New config is says that the drives will be erased, that sounds bad? Will it actively erase the disks if I do that or is that why I need to tick that parity is ok so that it doesn't? I tried just assigning a new drive to disk 3, the old disk 4 to drive 4 but that still wont let me start the array, too many failed drives.

Here you go.

Ok, so disk 3 (sdg) is the one that is totally broken, i.e. can see it in list but can't mount it at all, it was the second one to fail. Disk 4 is I am assuming sdc, if it's showing as removed how would I go about adding it again? In terms of getting the server back to full functionality, I will be ordering the remaining drives over the next week or so but just wanted to get the array online as I currently can't access it to copy any important stuff off. Is there another way of getting stuff off the drives without getting the array back online? SMART wise Disk 1 and 5 both have warning so will be next replacements, rest still have green thumb. I am able to mount sdc and see data so would I be able to either assign it back as disk 4 and put a new disk onto disk 3 to get array online, copy data off it then replace it too or is that not possible? Could I put in both new drives to get array online and then just copy back data from the sdc drive? Assuming though that with 2 new drives the parity is broken so the array can't be rebuilt properly? Then for Disk 1, if I put a 4TB drive in to replace that for parity would that mean a higher level of redundancy as it's larger than the other drives or is redundancy always based on 1 drive max failing?

Here you go. Getting 2 new drives tomorrow so can then use them if needed. slyder-diagnostics-20160516-1858.zip

Hi, I have a system running with 7 X 2TB drives + 1 128gb ssd, all older drives from a previous server. All drives are running on onboard sata. One of the drives, drive 4, failed so I ordered a new one, due to no stock in area drive took 2 weeks to deliver, set for delivery tomorrow. The problem is that in that time another drive has failed, joys of using older hardware. So the problem now is drive 4 is actually back as an unassigned drive, if I try to assign it to drive 4 it says it's a new drive, so it seems to have forgotten that it was drive 4. Drive 3 just says format so that seems to be totally broken, before dying it was also showing errors. I can mount drive 4 using a plugin and browse the data on it so should be able to get the data off, the problem is that I can't start the array. What would be the best way to get things working without losing data? Is it possible? I ordered another 2TB drive today so will have 2 fresh drives to replace the old ones but not sure if adding 2 blank drives is enough to start the array with 2 failed? Thank you.
