I'm guessing that was I downloaded e2fsprogs-64bit-x86_64.tar.bz2 from somewhere (unfortunately I can't recall from where, but it was some link from a page about ext4) and used the mkfs.ext3 from there, which ldd tells me is statically linked.

As I've just replaced the old 400G disks with 1TB disks, all the old data is gone anyway, so any crashes or whatever won't immediataly lead to problems :-) Paul Slootman -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
