That's no more interesting than the simpler problem that when you go
to extend a sequential file, the write request fails even though the
filesystem has space available.
This was in the context of an application having used the posix_fallocate() call. If that call succeeds, the application is guaranteed to be able to use the storage that has been so allocated. Thin Provisioning breaks this, and it's far from clear how to fix it.
