Subject Re: Error waiting for SolrCore to be created
Date Fri, 14 Dec 2018 03:05:02 GMT
So I don't know what to recommend except rebooting.
Solr (actually, Lucene)  would _not_ delete that file without
replacing it. There is a great deal of care taken to insure
that the index is consistent and I haven't heard of the
segments file disappearing by itself, some external process
is very likely responsible.

I'm afraid the only thing I can recommend just blowing the
data directory away (rm -rf
while Solr is shut down and re-indexing from scratch.

I suppose some of the Lucene folks might have magic for creating
a new segments* file, but frankly that'd be suspect given
the unknown state of the segments.

Sorry I can't be more help,
