Re: solr directories

[Erick Erickson]

If you have legacyCloud set as true, then when the various Solr
instances come back up they re-construct their state. The "smoking
gun" here is if the data is in clusterstate.json in your new
Zookeeper.

If that's not operative, is it possible that you're still starting the
embedded Zookeeper and getting data from _there_?

Best,
Erick

solr directories

[Satya Marivada]

Hi,

We had solr running on embedded zookeeper. Moved to external zookeeper, as
part of this setup on the same vm, had done a fresh solr distribution
setup, zookeeper distribution and created new solrdata folder to hold the
nodes. All the old folders are archived (zipped and backed up). What
wonders is the new deploy pointing to external zookeeper still shows the
old collections that were created on embedded zookeeper on the solr admin
console. How is that possible, when I did a clean fresh install of the solr
distribution and zookeeper distribution. Is that the old collection
information stored in another location as well apart from solr-6.3.0
distribution package, zookeeper-3.4.9 package and the solrdata folder?
Would solr write into any other directories?

Thanks,
Satya

Solr directories in 4.3

[Raheel Hasan]

Hi,

I am starting a fresh project. Could someone please explain to me what
folders are needed here?
[image: Inline image 1]
I know solr and lib are needed. But what are all these other folders
there for?

Thanks.

Raheel, 

I can see the image, the mailing list doesn't work well with images, maybe you 
can upload the image in a site like http://picpaste.com/ and after share the 
link.

Re: Solr directories in 4.3

[Daniel Collins]

The example is just that, its an example, not a cast iron base to work from.

contexts, etc, lib, resources, solr-webapp and webapps are part of/related
to the Jetty deployment. You might not need all the files in them though.

cloud-scripts is just some sample scripts for accessing ZK (optional and
only if you are using Solr cloud).

example-DIH, examplesdocs are various example things (as the names
suggest), either data or Data Import Handler related configuration

multicore is an equivalent of solr for multiple cores, so you probably
don't need that.

solr contains the configuration, schema, and solr.xml/zoo.cfg (which I
believe are being deprecated in favor of configuration in ZK itself).

Certainly, you can remove the 2 example directories, the rest you'll have
to look through and work out if you need it.  It depends exactly what
configuration you are trying to create as to what you need (single
standalone core, multiple cores, Solr Cloud, etc) but that should give you
a start.

ok thank alot for the fantastic explanation.
Maybe your reply should be added into the README file that is in that
folder..

Re: question about Solr directories on mounted file systems

[Walter Underwood]

I've seen a nasty problem like this. When the mounted filesystem goes away,
you can create regular directories and files under the mount point. When
it comes back, the newly created files are not accessible. Yuk. --wunder

 can you clarify what you mean by this?

Ahhh  i see what you mean.  isn't the solution there to make sure the 
data directory (on the mounted filesystem) is writable by solr but that 
the parent directory (ie: the mount point) isn't writabl? ... so solr 
can't create the directory in the event that the mount point isn't there?

question about Solr directories on mounted file systems

[Jim Adams]

I have an application that is using SOLR on a mounted file system.  However,
machine or human error can sometimes unmount the file system.  This causes
Solr to write index files to a different area from the index I am using.

This also means that the index instance becomes corrupt, because some
entries are in the (correct) index, and some are in the one that was created
because the mounted file system was missing.

Is there an option in Solr that says Do not write to the index if the
directory path does not already exist?  Or some other way of ensuring that
I don't get multiple index instances created unintentionally, in a situation
such as this?

Thanks!

Re: question about Solr directories on mounted file systems

[Walter Underwood]

I do not recommend using Lucene or Solr on a mounted file system.
My implementation was 100X faster after I moved it from NFS to
local disk. --wunder
