Hi folks
We're upgrading some 4.2 sites to 5.6 using a workflow along the lines of-
(briefly- copy v4 webapp to new server, deploy customised code, ant update
on that new build).
Looks ok, other than the rather big issue of solr. I get the following when
running indexing on any of the solr indexes (search the main one, but I get
similar problems on statistics, oai, authority too). Advice from other
failures suggests permissions, but these folders are owned by the same user
that runs tomcat (dspace) and they're let's say "as open as on other
repos". I've tried copying in other indexes to try and improve the
situation, but the error is the same (complains in particular about
"segments_XXX" which I've never seen anywhere, so I am not sure what is
calling it). The issue definitely seems to be a failure to initialise
search, based on not finding "a file". No write locks remain to hinder it
either.
If anyone has any suggestions, I'm willing to try them.
Cheers
Scott
