리노드를 다른 리노드로 복제

[b]다른 Linode에 리노드의 구성 /디스크복제[/b]

이 기능을 사용하면 계정에 연결된 다른 Linode에 Linode의 구성 및 데이터를 복제할 수 있습니다. 복제할 전체 구성 프로파일을 선택할 수 있으며, 이는 대상 Linode에서 구성 프로파일을 자동으로 만들고 해당 구성 프로파일과 연결된 모든 디스크 이미지를 대상 Linode에 복사하거나 복사할 개별 디스크 이미지를 선택할 수 있습니다.

이것을 구현하는 것은 내가 처음 생각했던 것보다 더 복잡했기 때문에 일부 테스트는 감사할 것입니다. 데이터 센터 간에 큰 디스크 이미지를 복사하는 데 시간이 걸릴 수 있습니다.

즐길!
-Chris

    Coolness! This would be very handy setting up redundancy across datacenters…

    Or even within the same data center, with Linodes on separate hosts and using the new HA / IP Failover feature:

    What are you guys trying to do, put all of your competitors out of business??? How can they avoid bankruptcy if you keep this up?

    Wow. What a useful feature. I really appreciate you implementing this. It makes testing changes to a production server so much easier without the need to shut it down for long periods of time.

    Are we still being "charged" for the bandwidth this process would use?

    If yes; can you make it possible to run two linodes on the same physical server so that any backups of this kind would be from localhost to localhost and thereby not generate any traffic on the network? That way you could choose not to charge for the bandwidth generated by a backup process.

    The copies run from host to host, rather than from within a Linode to another Linode .. if that makes sense. So, no — this isn’t deducted from your transfer allotment.

    Enjoy — let me know if I missed some bugs 🙂

    I assume the OS better be configured for DHCP else the same IP address might come up on both linodes…

    It makes sense. And is wonderful!

    I just finished backing up my production linode disk image to my other linode. They are both in the same data center (Atlanta) and the backup of 2048 MB took 10-11 minutes. I tried to not shut down the running production server before clicking the "clone button" just to see if it would work anyway. It seems to have worked. Me and 2-3 other users are the only users of it, so I guess it worked due to very low disk usage on my production server.

    Anyway.. I edited a mediawiki page on one of the servers and clicked refresh on both. The update only registered on one of the servers which is how it should be. I haven’t done any more testing but it seems that this cloning feature you have implemented works just as I expected.

    I noticed that the Dashboard job only got visible on the receiving linode account and not on the sending linode account. That is no biggie but would be nice if you fixed.

    Unlikely. The MAC address of a linode is based on it’s bridge, which I think is some magic caker sets up to be unique.

    That controls your IP, *if* you’re setup with DHCP. But if you modified your config for a static (as in fixed, hardcoded) IP, and then replicate that disk to another linode, it would be Not Good.

    We filter layer 2 and layer3 traffic, in and out, that does not belong to the Linode in question. So, worst thing that can happen is that it boots without an accessible IP address.

    Now, if you have the [url=https://www.linode.com/forums/viewtopic.php?t=2933]IP Failover[/url] stuff configured to allow those IPs to come up elsewhere, then yes — it’ll be bad.

    I am wondering if it is possible to clone a Linode VPS to another user account?
    Cheers

    I am looking at Linode planning to shift from Rackspace one req is creating and removing nodes through api . My question is does the linode.clone() create 100% clone of existing node along with the non OS files i.e install in /var/www/html or else where and other installed apps on the machine

  13. Author Photo

    the aplications that i have in the server to be cloned must be stoped or they can be running?

    I too am looking for a way to vend a “golden” image to customers who would use that image to launch nodes in their own Linode Cloud Manager.

  15. Author Photo

    This is a great use-case for golden images! Here are some options:

    If you have access to their account, this guide walks you through sending and receiving a disk image.

    Otherwise, you could create a local copy, which you could then deliver to a customer.

    Lastly, you could clone a Linode on your own account, then reach out to Support to transfer that Linode to a customer’s account — just keep in mind that the customer would have to make a matching request to Support.
