Strange replication problem
Hello list,
I'm trying to set up a replicating solr system (one master, one slave) here.
Everything _looks_ o.k. but replication fails. A little debugging shows the following:
root@slave:~# curl 'http://master:8180/solr/website/replication?command=indexversion&wt=json' && echo ''
{"responseHeader":{"status":0,"QTime":0},"indexversion":0,"generation":0}
root@slave:~# curl 'http://master:8180/solr/website/replication?command=details&wt=json' && echo ''
{"responseHeader":{"status":0,"QTime":1},"details":{"indexSize":"6.76 GB","indexPath":"/var/lib/solr/data/website/index","commits":[["indexVersion",1292192351652,"generation",5,"filelist",["_7e.fdx","_7e.tii","_7e.frq","_7e.prx","_7e.fdt","segments_5","_7e.fnm","_7e.nrm","_7e.tis"]]],"isMaster":"true","isSlave":"false","indexVersion":1292192351652,"generation":5},"WARNING":"This response format is experimental. It is likely to change in the future."}
root@slave:~#
Note that indexversion returned by the indexversion command is 0 while the same information from the details command is 292192351652 ...
Any idea what's going on here?
TIA Ralf Mattes

did you double check
http://machine:port/solr/website/admin/replication/ to see the
"master" is indeed a master?

??? What part of my posted example did you not read? :-)
Both requests where sent to the same machine (configured as master) - and I get
exactly the result described. So, no, for my setup (pretty much out-of-the-box
with minimal master/slave configuration) your statement is wrong :-/

This only happens to a Slave machine. For a Master machine,
indexversion returns the same number as details command.
