Haim, looks to me like your NFS is messed up.
Seems like we wrote to disk but when reading the data is not there (see below).
It also seems to me like the same problems you're having with BZ#843511

looks to me like sanlock issue which is no more reproducible on SI12 with vdsm-4.9.6-24.0.el6_3.x86_64 and sanlock-2.3-3.el6_3.x86_64
