Do you see the same problem if you resize a physical disk, not just with loopback? Sounds like it... In theory it should be reproducible w/ lvm too, then, I think, unless there's some issue specific to your block device similar to what's happening on the loop device. > Instead you both are using truncate to grow the disk while the > filesystem is not currently mounted, and then mounting it. Always worth communicating a testcase in the first email, if you have one, so we don't have to guess. ;) thanks, -Eric -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
