Moving Files to new disks

Recommended Posts

Hey fellow Unraiders

 

I've bough 3*12TB in order to replace my 1*4TB and 1*3TB drives

Now the setup is

  • 1*12TB as parity (already in place and set up)
  • 2*12TB cleared and added to the array
  • 1*3TB and 1*4TB which are already in place

 

Now it's time to move files between disks in order to be able to remove the previous disks

 

I know the question may have been asked abnout how to transfer files between disk (and not Shares). I've found multiple answer but not a clear one of a recent one

 

I found Unbalance quite reliable in the past, I'm planning to use it, but today transfer speed are really slow, like 9-12MB/s

  • I've disabled parity to help with preventing writing to it, I'll redo the parity once done

 

Any suggestions ?


Thanks in advance

@trurl It's been now 24h and my array only managed to rebuild 1.59TB of Parity, despite numerous run at 110/120MB/s the days before

I don't see any errors on disk Smart results, cables are the same as before, the parity checks on 12/09 and 12/10 were both on the 12TB drive

Only change I had to do was cutting the 3.3V rail to power the 12TB drives, because they refused to boot otherwise

I think I've found the culprit here:

sdb is my 3TB drive, maybe it's becoming to fail, unsure why now though

 

new diagnotics attached
