eDirectory Recovery on Linux with DibClone


I received a question from my customer regarding using DibClone, as a
tool to restore all replicas in the environment (100+) to newly built
servers, instead of having to go through each of the newly built
servers, and add the replicas back on one at a time. Which in the
environment is a time consuming process. The TID document that was
located is from March 9 2007, though it was updated in April 2012. The
steps detailed there seem to be pretty straight forward, just wondering
if there might be anything newer for eDirectory 8.8.x?

Thank you in advance,

DS

Re: eDirectory Recovery on Linux with DibClone

DIBClone is great for building a new NCP Server object and its DIB from
scratch. It is not useful for building an entire environment from scratch
because it requires at least one Master of the partition (as well as any
other relevant servers in the server's replica rings) to be active. If
you have one server in the tree and you want to add nine more, it's a
perfect option. If you already have the nine other servers in the
environment, take them out, clean up the tree of their objects, then use
DIBClone and build them from that.

Re: eDirectory Recovery on Linux with DibClone


Good afternoon AB,

Thank you so much for your input. We did look through the eDirectory
8.8.8 documentation http://tinyurl.com/oyrhmbu

and after having spoken with another eDirectory specialist, they
suggested following the "Offline" method, which I will pass along to the
customer.

Will let you know how this goes for them.

-DS

Just keep in mind the limitations mentioned earlier. DIBClones cannot be
used to create a tree, just to add servers to a tree that do not currently
exist in partitions that have a health replica ring (obviously including a
Master). The Offline (vs. Online) method just refers to the state of the
source eDirectory system.

Re: eDirectory Recovery on Linux with DibClone


Good day,

Thank you for the additional assistance and details of the procedure.

One question that came up, was what state does this leave eDirectory in
while the DIB cloning process is taking place?

In answer to your comments above,

They are not creating a Tree.

They are adding servers to the existing Tree, and from what I have been
told the Replica Ring is healthy. I will pass along the link that you
provided. Sounds like this will be happening this afternoon with the
first server to be added using the DIB Clone method.

For the server being cloned, if you use the online method, you should not
be replicating. If you use the offline method that server's eDir instance
is stopped. All other servers (if applicable), in either case, are fully
functional.

> They are not creating a Tree.


Just to be pedantic, my distinction was meant to be make it clear that
even restoring a previously-existing tree (or any replica of any partition
lacking a healthy Master replica in the On state) will not work. Sounds
like you have this covered properly, though.
