Shehjar,

I tried latest version (3.2.3-1) for confirmation and got the same results.

machines:
  3 bricks:
         192.168.1.138
         192.168.1.140
         192.168.1.137

  2 NFS clients:
         192.168.1.254
         192.168.1.20

operations:
  OK case:
  192.168.1.20# mount 192.168.1.138:/323 /tmp/mnt
  192.168.1.254# mount 192.168.1.140:/323 /tmp/mnt
  192.168.1.254# dd if=/dev/zero of=/tmp/mnt/1G bs=1M count=1024 (see *1)
  192.168.1.254# rm /tmp/mnt/1G   (see *2)

  NG case:
  192.168.1.20# mount 192.168.1.138:/323 /tmp/mnt
  192.168.1.254# mount 192.168.1.140:/323 /tmp/mnt
  192.168.1.254# dd if=/dev/zero of=/tmp/mnt/1G bs=1M count=1024 (see *1)
  192.168.1.20# rm /tmp/mnt/1G   (see *3)
