Volume Crashed, but RAID good

[mrpeabody 0]

Hello, Below is what I am getting while trying to repair my crashed volume using SSH. There is no repair option via the GUI. The Volume is the only part I see with any errors. Any help would be much appreciated. I have search and got the command below to resolve it , but as you can see it does not work.  

 

 

 

sudo e2fsck -ccDfttvy -C 0 /dev/vg1/volume_1

e2fsck 1.42.6 (21-Sep-2012)

ext2fs_open2: Bad magic number in super-block

e2fsck: Superblock invalid, trying backup blocks...

e2fsck: Bad magic number in super-block while trying to open /dev/vg1/volume_1

 

The superblock could not be read or does not describe a correct ext2

filesystem.  If the device is valid and it really contains an ext2

filesystem (and not swap or ufs or something else), then the superblock

is corrupt, and you might try running e2fsck with an alternate superblock:

    e2fsck -b 8193 <device>

First: please be calm and wait for an answer from other forum members. There's no need to post another answer within a few hours to push your thread.

 

Regarding your problem: please describe your setup. Which RAID type did you set up? SHR? RAID X? Filesystem?

Are you sure you are not using ext4 (or Btrfs)?

This guide might help if you are using ext4.

It was btrfs

Then using an ext filesystem utility (e2fsck) is ill advised.

 

btrfs really doesn't have any user-accessible repair options in Synology.  It's mostly designed for self-healing and then if that doesn't work, Synology remote access recovery.

 

Here's a data recovery thread from awhile back.  If you want better advice, post some screenshots or more information about your issue.
