ebs volume - can't read data

Question

hi guys, so i have this volume: vol-0f057741ae7be8974 - this worked till today. today my instance stopped working and when i attached this volume to another instance, i can't read the data off it. is there any chance we could recover the data? i forgot to take a snapshot of it :/  
  
i have also tried taking a snapshot of the volume and creating another volume but still no dice on mounting it:  
  
_mount: wrong fs type, bad option, bad superblock on /dev/xvdg,_  
       _missing codepage or helper program, or other error_  
  
       _In some cases useful info is found in syslog - try_  
       _dmesg | tail or so._  
  
_\[ 3074.328710] XFS (xvdg): Invalid superblock magic number_  
  
thanks in advance

Answer

Was the volume encrypted?   
  
I would suggest take a snapshot, create a volume, attach to a new Linux machine and then:  
  
1) Check the output of

```
fdisk -l /dev/xvdg
```

2) Run

```
xfs_check /dev/xvdg1
```

3) Check what you get

```
sudo xfsdump -f /dev/xvdg1 | grep -i superblock
```

4) Still no luck then try
 `sudo mkfs.xfs -N /dev/xvdg1`
. If you see some numbers there, you may be able to recover the device using a tool like   
  
If nothing works, you are probably out of luck.
