When Lucene optimizes the Index (which it semi does naturally as the
index grows) it creates a copy of the index, so you can expect the space
requirements for an index to be double the index at an absolute minimum.
If you are adding 20,000 docs a day and working with an index that is
already 20 G than your just playing with fire sitting on a 50G
partition. With the price of disk-space these days I would recommend
throwing a lot more storage at your appserver. I would hate to keep
dancing around as I gave it the few more Gig it needed to keep from
crashing.

Hi All,
I am using lucene 1.9.1 for search functionality in my j2ee
application using JBoss as app server. The lucene index directory size
is almost 20G right now. There is a Quartz job that is adding data to
the index evey min and around 20000 documents get added to the index
every day.When the documents are added and the segments are merged,
the index size increases and sometimes grows to more than double its
original size. This results in filling up the disk space. We have
allotted a f/s size of 50G and even that is not sufficient at times.
Is there an optimum vales for the f/s size to be allotted in such
scenario.
Any suggestions would be appreciated.
Thanks,
Harini
