[jira] [Commented] (CLOUDSTACK-2792) Redundant router: Password is reset again after fail-over happened

["Sheng Yang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-2792?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13758555#comment-13758555 ] 

Sheng Yang commented on CLOUDSTACK-2792:
----------------------------------------

Reopen the issue, because if the update of RvR state delayed in mgmt server side, both router would received "saved_password". It won't update the password then.

Would change mechanism to judge in VR rather than mgmt server side.

> Consider this scenario with RVR and "Password protected" VM:
> ============================================================
> 1. Both Master and Backup is running.
> 2. We reset the password on VM
> 3. Both Master and Backup have password; for example say; "password1"
> 4. VM boots up and requests for password; receives it from Master VR
> 5. Master VR sets the password to Saved_Password and Backup VR continues to
> keep "password1"
> 6. Backup VR goes down; it had password as "password1"
> 7. Maste VR is running
> 8. We reset the password; so the password is only changed to Master VR (as
> Backup VR is down); for example "password2"
> 9. VM boots up and requests the password; gets it as "password2"
> 10. Master VR sets the password to be Saved_Password
> 11. Now Master VR goes down
> 12. Backup VR was brought online (it still has "password1")
> 13. Now we reboot the VM
> 14. It sends a password request
> 15. Backup VR (which is only available now; so is Master) sends the password as
> "password1"
> User tries to login as "password2" and he cannot; unless we reset the password
> again.
