pwvandeursen Posted March 10, 2015 #1 Posted March 10, 2015 Hi all, yesterday I got a warning in my DSM that my volume had crashed. the DSM asked me to reboot which I havent done yet, i.e. the synology is still running. My system is the following: asrock q1900 2 * wd 3tb red nas both in basic (no protection) volume 1 is crashed. In the file manager I can still see some of my documents. in other folder nothing is visible anymore. The strange thing is I can't copy anything from the volume 1 to volume 2, even if the filemanager sees the files. What can I do, or is all the data basically lost? I just ordered 2 extra drives, hopefully to download some of the data, if not to set up a RAID to not have this hapen again. some of the data was backed up, but not all of it (most important, i.e. foto, music, docs where, all the films serie etc are lost. 1.7TB of data.. any help is appriciated
thomas Posted March 10, 2015 #2 Posted March 10, 2015 Hi, You can try to mount the drive under linux (ubuntu) and check/copy the data. See the link below for a tutorial http://superuser.com/questions/550064/how-mount-find-recover-data-in-hdd-outside-of-synology-box I tried under ubuntu 14.10 live cd and it worked for me. Make sure that you adapt it for your drive (sdc5).
pwvandeursen Posted March 10, 2015 Author #3 Posted March 10, 2015 thanks for the reply. which did you try the other solution he is referring to or the one in the answer? I don't have a linux machine, so could try with a live boot CD, and the connect the drive with a USB cable to the laptop with Ubuntu. would that work? How do I check which sdc my drive is?
thomas Posted March 10, 2015 #4 Posted March 10, 2015 I tried the one in the answer. For the drive to be attached to the USB you need an adapter with external power. Easiest check is sudo fdisk -l and the answer will be something like Disk /dev/sda: 8589 MB, 8589934592 bytes 255 heads, 63 sectors/track, 1044 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00008ec7 Device Boot Start End Blocks Id System /dev/sda1 * 1 1013 8136891 8e Linux LVM /dev/sda2 1014 1044 249007+ 5 Extended /dev/sda5 1014 1044 248976 83 Linux You have to identify your wd red drive and change the mdadm -A --verbose --run /dev/md3 /dev/sdX5 accordingly. If you have only 1 drive attached to the computer it should be sda, if you have 2 it's either sda or sdb ...
