And I can attest to growing ext4 > filesystems online is deadly. :-/ .28 was the first kernel where ext4 was marked stable. With good reasons, it seems... The .26 problem may be: Kernel 2.6.26 doesn't support ext4 (it probably has ext4dev support). As soon as the first extent-based file is created on a ext3 mounted as ext4, the filesystem is ext3 incompatible. Generally I'd use ext4 only with 2.6.28+ as it was marked stable in that version.
