Oh, interesting. I didn't know that was possible. And even better: Linux has fallocate() that can do it for other filesystems than just XFS. Or looks like it's only XFS and ext4 (ext3 doesn't support it).
How about reiserfs (3, not 4)?
Doesn't support.
Is it possible with UFS and ZFS?
Linux doesn't support either and my googling didn't find any FreeBSD or Solaris interface for this feature, so I don't know.
AIX supports posix_fallocate but only for JFS2. For GPFS(what we use), the function is gpfs_prealloc.
