Volume crashed after Restore Proxmox

[adribou]

 

 

Hello,

I am relatively new to the xpenology and require some help after a volume crashed on my xpenology used on proxmox.

After messing up with the nginx configuration, i had the brilliant idea to restore a proxmox backup and ruined my configuration  

 

I have a configuration with 3 HDD and i can not access the data anymore.

I mades some research on my own but can not resolve the problem.

sudo mount /dev/vg1/volume_1 /volume1
mount: /volume1: /dev/vg1/volume_1 already mounted or mount point busy.

ls /volume1/
hs_err_pid14125.log  hs_err_pid6647.log  hs_err_pid8895.log
hs_err_pid6332.log   hs_err_pid8487.log  hs_err_pid9220.log

 

Mount is ok but i can not access the data anymore.

Is there a way to recover the date ?

 

Thank you very much !

Try using the recently released btrfs volume mount feature.
