Recovering data when JBOD disk fails
« on: May 26, 2014, 06:05:06 AM »
I have set up JBOD on 2 HDDs (2TB and 1TB, unfortunately as 1 volume) and the 2TB HDD failed (it is still readable, but some files are not accessible anymore).

I have bought a new 3TB HDD and I need to recover all the data I can. I have an old computer where I have the NAS, so I cannot connect the 3TB HDD to that computer and transfer the files.

I tried to put the 3TB HDD along with the 2TB and I managed to copy most of the data on it, but when I connect the 1TB with the 3TB, I cannot see the volume on the 1TB and also a yellow/orange light is on. Any idea how to recover the data on the 1TB HDD without connecting the 3TB HDD on a different computer? Basically, I would need to rebuild somehow JBOD on the 1TB HDD so I can view it when the 3TB HDD is connected. I have access to console via funPlug and SSH, but no idea what to try.

Since you are trying to recover tour data I assume you don't have a backup.

Depending on what you want to do with the 3TB drive you could use that as your backup unit.  

To do that you need to get a USB/SATA disk caddy with an external power supply.  

Once you have that with your 3TB drive installed plug it into your PC and let the operating system format it.  When that is finished all you have to do is copy the undamaged files from the NAS to that drive.  

With your files now backed up you can do what is necessary to determine the problem with the disks of the NAS, replacing and reformatting as necessary.

When that is ready just copy your files back and use the 3TB drive for your weekly backup of the NAS using RSYNC.
