Hi Shawn, I do have persistent="true" in my solr.xml:<?xml version="1.0" encoding="UTF-8" ?> <solr persistent="true"> <cores adminPath="/admin/cores"> <core name="default" instanceDir="./"/> <core name="413a" instanceDir="./"/> <core name="blah" instanceDir="./"/> ... </cores> </solr> the command I ran was to rename from '413' to '413a'.
I think I see the problem. You have three cores that all point to the same instanceDir, and no dataDir parameter. Normally the dataDir parameter defaults to "data" in the instanceDir, but perhaps if you have multiple cores sharing the instanceDir, it will use the core name instead. With this solr.xml, I can see why you're having a problem. The solr.xml file doesn't tell Solr where the dataDir is.
If you set up an explicit dataDir option for each core, then it should work out the way you expect it to. Here's an excerpt from my solr.xml:
<core name="s0live" instanceDir="/index/solr/cores/s0_1/" dataDir="/index/solr/data/s0_1"/> <core name="s0build" instanceDir="cores/s0_0/" dataDir="../../data/s0_0"/>
You are correct about what happens with my directories on a swap, but because solr.xml gets updated and has an explicit dataDir for each core, everything works.
Thanks, Shawn
