my local disk is very small,just can store one day index files.So i wanted  
to move my index file to another fs path.  
This is my sh.It excute everyday.  
#!/bin/bash  
#copy the index files form elasticsearch to clusterFS now  
ddate=`date -d "1 days ago" +%Y.%m.%d`  
clustername="mams\_online\_log"  
indexdir="/data/soft/logmonitor/elasticsearch-1.1.0/data"  
ipip=$(hostname)  
dstdir=/mnt/lego-log/$ipip  
echo "Start time: $(date "+%Y.%m.%d %H:%M:%S")"  
echo "$dstdir"

# copy the old index file;

mkdir $dstdir  
cp -r $indexdir/$clustername/nodes/0/indices/logstash-$ddate $dstdir/  
mv $indexdir/$clustername/nodes/0/indices/logstash-$ddate  
$indexdir/$clustername/nodes/0/indices/tmp  
ln -s $dstdir/logstash-$ddate  
$indexdir/$clustername/nodes/0/indices/logstash-$ddate  
rm -rf $indexdir/$clustername/nodes/0/indices/tmp  
echo "ok"  
echo "End time: $(date "+%Y.%m.%d %H:%M:%S")"

But when i "lsof" this is always so many files used by the es pid.  
So how i can do for this ?

Basically you can't do with no stop at all. ES holds indexes open so that  
it can access the data quickly. You could close the index, copy the data  
and then open the index again but it is probably best to stop es, move the  
data, change the data path and then start es again. You can have multiple  
data paths so that you can skip the copying but you need to restart es.

How about closing index before moving files? Does it fit your need?
