Off topic:Du -Hs Casava_V1.8.2 : 8.2T !!????

Question

[Pierre Lindenbaum]

I've downloaded CASACA 1.8.2 and installed it on our cluster.

cd /commun/data/packages/CASAVA_v1.8.2
mkdir CASAVA_v1.8.2-build
cd CASAVA_v1.8.2-build
 ../CASAVA_v1.8.2/src/configure --prefix=/commun/data/packages/CASAVA_v1.8.2
make
make install

here is the output of du -hs :

[root@master CASAVA_v1.8.2]# du -sh *
26G    bin
135G    CASAVA_v1.8.2
8.2T    CASAVA_v1.8.2-build
2.0G    CASAVA_v1.8.2.tar.bz2
1.0G    etc
91G    lib
47G    libexec
809G    share

8.2T !!! what is wrong ??? how can I clean this ? or can I just delete this CASAVA_v1.8.2-build ?

one big directory is:

du -hs /commun/data/packages/CASAVA_v1.8.2/CASAVA_v1.8.2-build/opt/bootstrap/
7.4T    /commun/data/packages/CASAVA_v1.8.2/CASAVA_v1.8.2-build/opt/bootstrap/
