so i am new to this software and i am sure i may have overlooked something. but for now i need to get backups working. so here is the error message and stack trace info :

Exception chain:

 

  • Attach device failed for device path of '/dev/dm-0' with error code 19
  • Call to service method 192.140.500.799:8006/.../driver GET failed: Attach device failed for device path of '/dev/dm-0' with error code 19
  • The transfer of one or more volume images from a protected machine to the Core has failed
  • One or more errors occurred.

So far the root partition cannot be backed up. i have only been able to back up the swap file ... no idea ... as far as i can tell the agent is the latest one available. the system is ubuntu 16 64bit. any suggestions

  • There may be various causes:
    1. One of the services are stopped (rapidrecovery-agent, rapidrecovery-vdisk, rapidrecovery-mapper)
    2. Agent version mismatch with core version.
    3. Services modules are not loading.
    4. Kernel headers installed are not correct.
    ----
    It is likely that configuration needs to be run:
    - rapidrecovery-config -m all
    Should you see errors about the kernel headers, re-run agent configuration
    - rapidrecovery-config
    -- select option "6 on"
    -- select option "4 all"
    - check the service "service rapidrecovery-vdisk status"
    - start the service "service rapidrecovery-vdisk start"
    ----
    The above suggestions just cover a commonly seen situation.
    If in doubt after these steps, we suggest that you reboot the linux server, and check again.

    Should you find other issues, or need assistance troubleshooting, we suggest that you please open a service request from our support portal.

    I hope this helps.
