It's a raidz1 pool build with 5 SATA 2TB drives, and there are 5 zvolumes
without advanced features (no compression, no snapshot, no de-dup, etc...).
Because it's a raidz1 pool, I know that FREE space reported by a "zpool
list" include redundancy overhead and is bigger than AVAIL space reported
by a "zfs list".

I've moved about 100GB (on hundred GigaByte) of files and after this step
there were only 2GB (two GigaByte) of Free space only: How is it possible ?

About the zpool status:

  pool: storage
 state: ONLINE
