I'm pretty sure that I have filesystems with mixed extent- and block-mapped files that I've resized in the past. That said, depending on your data's importance, and your tolerance for risk you should probably have a backup of your data anyway. At that point, starting with a fresh ext4 filesystem and restoring from backup is also attractive for the performance improvements of extents, as well as other format-time only features. My filesystems have a high turnover rate (PVR) and are not impossible to replace, so I have been resizing in place and letting normal turnover of files migrate to extents. I still don't have some if the newer filesystem features.

At the rate data is added to the file system it will fill up in a few months so I'm weighing my options. One option would be to create a new ext4 file system and copy everything over to a new, larger ext4 file system. Another option would be to modify the software that uses this file system so it can use multiple file systems. Finally, I could could convert the existing file system to ext4 and then resize it. Is this advisable?
