  1. Despite the unfortunate result, I really appreciate your help. You did a lot for me. I wish there were more professionals like you. Have a nice day
  2. This is the log of the commands: root@XP:~# btrfs ins dump-super -Ffs 67108864 /dev/md3 superblock: bytenr=67108864, device=/dev/md3 --------------------------------------------------------- csum 0x00000000 [DON'T MATCH] bytenr 0 flags 0x0 magic ........

  4. You are right - it was btrfs root@XP:~# btrfs rescue super-recover -v /dev/md3 No valid Btrfs found on /dev/md3 Usage or syntax errors Segmentation fault (core dumped)
  5. Thank you.

  6. Do someone have a technical manual for DMS ? I want to try to add the disks in the RAID in Linux configuration files. Thanks
  7. What happened before? I think the volume was overflowing. The web access to the storage returned a message like: the system cannot display the page (Synology's error message, not a standard browser error) After reboot the system asked me to install DSM again. After installation I get this situation. No addition actions were performed. I agree that trying to manually add disks to the raid it's only option with some chance to success. I will be grateful if you can tell me how to do this. Thank you
  8. I think so (like on pic 1) root@XP:~# fdisk -l /dev/sdh Disk /dev/sdh: 5.5 TiB, 6001175126016 bytes, 11721045168 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: gpt Disk identifier: 987F18E3-DCA2-431A-9174-AADC0F9C53EC Device Start End Sectors Size Type /dev/sdh1 2048 4982527 4980480 2.4G Linux RAID /dev/sdh2 4982528 9176831 4194304 2G Linux RAID /dev/sdh3 9437184 11720840351 11711403168 5.5T Li
