Each Tar archive is around 15Go
Restarting the daemon seems to solve the problem :

But my main preoccupation is " Is it a normal behavior for glusterfs ?"

This issue appears after those 2 scripts running during 2 weeks :
test_save.sh is executed each hour,it takes a bunch of data to compress (dest :

script will scan each 30 min
