UAS is "USB Attached SCSI", and this error indicates some kind of hardware issue (maybe a loose cable connector?). If you can't replicate the failure, it might be because it's a one-off hardware problem. One thing I would suggest is running e2fsck -f after shrinking the file system using resize2fs. If there is any corruption that you can see when using resize2fs with shrinking, preferably with a fixed HDD or SSD which is known to be good (USB cable instability is a nightmare and I generally don't recommend people to use USB attached storage on laptops because laptops tend to move, and USB cables getting jostled is a really common problem). So from a problem isolation perspective, it's really helpful to try to isolate variables. So if you can try to isolate the problem using a image file stored on a fixed storage device, and then try shrinking the file system on the image, so we don't have to worry about gpart bugs, hardware bugs, etc., that is really helpful. And if you use e2fsck to make sure the file system is consistent, as opposed to waiting for the kernel to trip on the file corruption, that would be also very helpful. If you are paying $$$ to Canonical, then there will be much more likely to be Ubuntu support engineers will do this sort of fault determination procedure. As an upstream developer for e2fsprogs, however, I'm really not going to get involved until you can give me a reproducible test case that doesn't require your specific hardware --- hence the request to see if you can reproduce the problem using an image file without using hardware and partitions. If this is really dependent on which partition is involved, then this might be a gpart bug. And no one (and certainly Canonical!) is paying me to try to debug gpart. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to e2fsprogs in Ubuntu. https://bugs.launchpad.net/bugs/1860917 Title: uas_eh_abort_handler uas-tag inflight OUT Status in e2fsprogs package in Ubuntu: New Bug description: 591/5000 Hello To try to understand this incident ( https://bugs.launchpad.net/ubuntu/+source/gpart/+bug/1857914 ) which systematically occurs in version 19.10 and which I cannot (yet?) reproduce in version 18.04.03, I made a test game. Using this test game consisting only of cp and diff commands, I caused a similar problem. The first visible consequence which seems serious to me: The copied file is not identical to the sending file. It seems that the blocks are shifted. It would be desirable for the user to be warned that the written files have become incorrect. Thank you for your advice.
