GSA Mirroring - how to?

[ash]

Hi All,

I have two GSA boxes. I need to make one as Primary and the other one
as secondary (replica of the first one to be used as failover).

I'm performing a Feed and not crawl.

I have done all the steps mentioned in the documentation
http://code.google.com/apis/searchappliance/documentation/62/dist_crawl/dist_crawl.html#ConfigIndexRep

I have a record indexed in the primary GSA. But this does not get
replicated to the other one.

- Does the indexes automatically gets copied on to the second GSA?
- Do I need to perform feed to both the boxes?
- If this can be done, how to do it?
- If this cannot be done, what is exactly meant by GSA Mirroring?

Please can anyone help me out with answers for these questions?

Thanks in advance,
ash.

Hi Ash,

I know there are still some open bugs with Multibox as per the release
notes:
https://support.google.com/enterprise/doc/gsa/relnotes/relnotes_620G14.html

But it would probably be a good idea to get it updated to 6.2.0. at
least. For mirroring you should only need to send feeds to the master
node and it should eventually be copied over (may be a slight
timelag). As a test rather than messing with just feeds, it would
probably be good to just have it crawl normally to make sure that
documents are indeed mirrored on the other appliance.

Hope this helps.

Brian

Hi Brian,

Thanks for you comments.

Our GSA boxes are already on 6.2.0. I have done few feeds yesterday
and they are not yet mirrored to other appliance yet.

So, are you suggesting not to use this feature for now?


Thanks,
ash.

Hi Ash,

In the release notes for version 6.2 Google listed the folling Issue:

2194738 - Mirroring can result in data corruption on the replica node.
A patch for mirroring is targeted to be available by January 1, 2010
(all dates subject to change) and we recommend that customers wait for
the patch before using this feature.

This may be effecting your primary's node ability to transfer the
index to the secondary appliance. Therefore as Google state that you
should not use this feature until a patch is released, you should just
submit the feed to both Google Search Appliances.

When the patch has been released, clear the index of you secondary
appliance and set up "Mirroring".
