xpenology as a recovery option


Question

I had a DS415+ that died either to the Atom bug or a power surge. Blue blinking power LED of death...

I'm able to access the data on the drives using a  linux box with this method

My problem lies in the fact that i had two ISCSI luns on the DS and those are apparently btrfs file based devices written on top of the md raid. I can see the @iSCSI folder and files in there that are named what my LUNs were.

If i get xpenology up in a VM and hand it the 3 physical drives will DSM see that they are synology drives and import them, keeping the data and previous configuration? This way i would be able to reconnect to the iSCSI luns and copy the data out.

To be a little bit more specific:  Practice installing on a spare drive until you understand the process completely and you have a combination of USB stick, DSM version and XPe loader that you are certain works with your hardware.

 

Then burn a new clean stick, and do the initial boot with your three array disks attached.  The Synology installer should offer to do a migration install.  If it suggests that your data is being overwritten in any way, don't proceed (you're picking the wrong option).

 

This is the only way to keep all your settings in place.  It is possible to import an array into a running DSM system but it will only preserve your data, not your settings.

I ended up going the vmware server route and it worked very well. The guides here were great and I ran into almost no problems. I did bring the DSM VM up initially without my drives attached to make sure it was up and working. Powered everything off and attached my drives, created the RDM mappings for them in vmware and attached to the VM. Initially i brought it up and it saw no drives then i figured out they needed to be on a second SATA controller in the VM and everything went great from there (my situation was different than the guides so i diverted a little, only had to read a bit further to find the second SATA controller clue). It offered to import them and my config, it rebooted and came up with the old static IP i had on the old NAS. Much to my delight the iSCSI LUNS were still shared. Connected to the LUNS on another PC and copied the data out. I'm glad Xpenology is around because i had no other options to get at that iSCSI data. Even opend a ticket with Synology and they said it's hard to get at and pointed me toward data recovery options. I did find a windows program that could scan the iSCSI files but it was seeing the file headers or something and none of the files had real names. just random numbers. I really didn't want to sift through 3TB of files renaming things...  Thanks again!
