Shouldn't be the case for regular ENOSPC (ie. when the space is reserved
in advance and with the possibility to fail early). If the transaction
is aborted, it means it's too late and there was some logic error.

Can you please describe more the fs and how did you fill it? Like single
process or multiple, dd or whatever.

david
