What you described might happen with lot of small files, but in our case,
our attempts fail to create a new inode and fail to write data. You suppose
that we have fractured free spaces, and on these fractures no inodes can be
created. In our case, the situation was different, however as it started to
work again I still can't provide you any xfs_info/debug.

Thanks again,
