Some more useful info: * This issue started to be caught by the testcase after the following test script change: https://kernel.ubuntu.com/git/ubuntu/autotest-client-tests.git/commit/ubuntu_nbd_smoke_test/ubuntu_nbd_smoke_test.sh?id=92ffd0ff14715392730943a898a95920b243ebef
* I have traced back these I/O errors on released from a couple of months ago. Checked xenial/linux-hwe and bionic/linux-azure. * This doesn't seem to affect the master kernel, bionic/linux. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1814237 Title: ubuntu_nbd_smoke_test failed with I/O error on X-4.15 Status in ubuntu-kernel-tests: New Status in linux package in Ubuntu: Incomplete Bug description: Kernel: 4.15.0-45.48~16.04.1 creating backing nbd image /tmp/nbd_image.img -------------------------------------------------------------------------------- Image path: /tmp/nbd_image.img Mount point: /mnt/nbd-test-25789 Date: Thu Jan 31 14:42:42 UTC 2019 Host: onibi Kernel: 4.15.0-45-generic #48~16.04.1-Ubuntu SMP Tue Jan 29 18:03:48 UTC 2019 Machine: onibi x86_64 x86_64 CPUs online: 4 CPUs total: 4 Page size: 4096 Pages avail: 1351388 Pages total: 2038431 Free space: Filesystem Size Used Avail Use% Mounted on udev 3.9G 0 3.9G 0% /dev tmpfs 797M 17M 780M 3% /run /dev/sda1 917G 9.1G 861G 2% / tmpfs 3.9G 4.0K 3.9G 1% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup tmpfs 797M 0 797M 0% /run/user/1000 tmpfs 100K 0 100K 0% /var/lib/lxd/shmounts tmpfs 100K 0 100K 0% /var/lib/lxd/devlxd cgmfs 100K 0 100K 0% /run/cgmanager/fs -------------------------------------------------------------------------------- NBD device /dev/nbd0 created found nbd export NBD exports found: test starting client with NBD device /dev/nbd0 Negotiation: ..size = 128MB creating ext4 on /dev/nbd0 mkfs on /dev/nbd0 succeeded after 0 attempt(s) checking ext4 on /dev/nbd0 fsck from util-linux 2.27.1 /dev/nbd0: clean, 11/32768 files, 9787/131072 blocks mount: /dev/nbd0 on /mnt/nbd-test-25789 type ext4 (rw,relatime,data=ordered) mounted on /dev/nbd0 free: Filesystem 1K-blocks Used Available Use% Mounted on /dev/nbd0 122835 1550 112111 2% /mnt/nbd-test-25789 creating large file /mnt/nbd-test-25789/largefile -rw-r--r-- 1 root root 100M Jan 31 14:42 /mnt/nbd-test-25789/largefile free: Filesystem 1K-blocks Used Available Use% Mounted on /dev/nbd0 122835 103951 9710 92% /mnt/nbd-test-25789 removing file /mnt/nbd-test-25789/largefile unmounting /mnt/nbd-test-25789 stopping client disconnect, sock, done Found kernel warning, IO error and/or call trace echo [ 4593.254552] creating backing nbd image /tmp/nbd_image.img [ 4595.506134] NBD device /dev/nbd0 created [ 4595.557990] found nbd export [ 4596.604855] starting client with NBD device /dev/nbd0 [ 4596.606795] creating ext4 on /dev/nbd0 [ 4597.013721] mkfs on /dev/nbd0 succeeded after 0 attempt(s) [ 4597.390241] checking ext4 on /dev/nbd0 [ 4597.455371] EXT4-fs (nbd0): mounted filesystem with ordered data mode.
