The fix is to ensure a rescan occurs. == Fix == Upstream fix fe1f9e6659ca6124f500a0f829202c7c902fab0c (" nbd: fix how we set bd_invalidated"). If a disconnect action happens the partition table gets invalidated and rescanned properly. == Testcase == Without the fix running the Ubuntu Kernel Team nbd smoke test will occasionally trip the bug and the error message from the kernel appears and the test fails. With the fix, this test has been run tens of times without showing the failure. To test run: autotest/client/local-test autotest/client/tests/ubuntu_nbd_smoke_test/control == Regression Potential == This fix touches just the NBD driver and has been upstream since May 2018 without any subsequent bug reports against it, so it is a known good fix. At most it sets the bd_invalidated flag more aggressively, so the rescan will occur, so I believe the regression potential is very limited just to ndb client connect/disconnect activity. --------- Reproduce rate: 2 out of 3 runs This issue can be found on other arches as well, normally it will fail with the first run and pass with the second attempt.   * Command:       /home/ubuntu/autotest/client/tests/ubuntu_nbd_smoke_test/ubuntu_nbd_smoke       _test.sh   Exit status: 1   Duration: 7.90551400185   stdout:   creating backing nbd image /tmp/nbd_image.img   --------------------------------------------------------------------------------   Image path: /tmp/nbd_image.img   Mount point: /mnt/nbd-test-13924   Date: Fri Mar 29 06:06:04 UTC 2019   Host: baltar   Kernel: 4.15.0-46-generic #49-Ubuntu SMP Wed Feb 6 09:32:48 UTC 2019   Machine: baltar ppc64le ppc64le   CPUs online: 160   CPUs total: 160   Page size: 65536   Pages avail: 1904339   Pages total: 2089666   Free space:   Filesystem Size Used Avail Use% Mounted on   udev 61G 0 61G 0% /dev   tmpfs 13G 12M 13G 1% /run   /dev/sda2 1.8T 11G 1.7T 1% /   tmpfs 64G 0 64G 0% /dev/shm   tmpfs 5.0M 0 5.0M 0% /run/lock   tmpfs 64G 0 64G 0% /sys/fs/cgroup   tmpfs 13G 0 13G 0% /run/user/1000   --------------------------------------------------------------------------------   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 2.31.1   /dev/nbd0: clean, 11/32768 files, 9787/131072 blocks   mount:   /dev/nbd0 on /mnt/nbd-test-13924 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-13924   creating large file /mnt/nbd-test-13924/largefile   -rw-r--r-- 1 root root 100M Mar 29 06:06 /mnt/nbd-test-13924/largefile   free:   Filesystem 1K-blocks Used Available Use% Mounted on   /dev/nbd0 122835 103951 9710 92% /mnt/nbd-test-13924   removing file /mnt/nbd-test-13924/largefile   unmounting /mnt/nbd-test-13924   stopping client   disconnect, sock, done   Found kernel warning, IO error and/or call trace   echo   [ 694.662746] creating backing nbd image /tmp/nbd_image.img   [ 695.821047] NBD device /dev/nbd0 created   [ 696.271555] found nbd export   [ 697.318393] starting client with NBD device /dev/nbd0   [ 697.323210] creating ext4 on /dev/nbd0   [ 697.589620] mkfs on /dev/nbd0 succeeded after 0 attempt(s)   [ 697.821953] checking ext4 on /dev/nbd0   [ 697.919173] EXT4-fs (nbd0): mounted filesystem with ordered data mode.

2019-04-02 16:30:51 Colin Ian King description == SRU Justification, BIONIC == Running the autotest regression test ubuntu_nbd_smoke occasionally trips I/O errors such as: [ 700.668758] print_req_error: I/O error, dev nbd0, sector 0 [ 700.668840] Buffer I/O error on dev nbd0, logical block 0, async page read This happens when the nbd client detaches and the backing store is removed. The fix is to ensure a rescan occurs. == Fix == Upstream fix fe1f9e6659ca6124f500a0f829202c7c902fab0c (" nbd: fix how we set bd_invalidated"). If a disconnect action happens the partition table gets invalidated and rescanned properly. == Testcase == Without the fix running the Ubuntu Kernel Team nbd smoke test will occasionally trip the bug and the error message from the kernel appears and the test fails. With the fix, this test has been run tens of times without showing the failure. To test run: autotest/client/local-test autotest/client/tests/ubuntu_nbd_smoke_test/control == Regression Potential == This fix touches just the NBD driver and has been upstream since May 2018 without any subsequent bug reports against it, so it is a known good fix. At most it sets the bd_invalidated flag more aggressively, so the rescan will occur, so I believe the regression potential is very limited just to ndb client connect/disconnect activity. --------- Reproduce rate: 2 out of 3 runs This issue can be found on other arches as well, normally it will fail with the first run and pass with the second attempt.   * Command:       /home/ubuntu/autotest/client/tests/ubuntu_nbd_smoke_test/ubuntu_nbd_smoke       _test.sh   Exit status: 1   Duration: 7.90551400185   stdout:   creating backing nbd image /tmp/nbd_image.img   --------------------------------------------------------------------------------   Image path: /tmp/nbd_image.img   Mount point: /mnt/nbd-test-13924   Date: Fri Mar 29 06:06:04 UTC 2019   Host: baltar   Kernel: 4.15.0-46-generic #49-Ubuntu SMP Wed Feb 6 09:32:48 UTC 2019   Machine: baltar ppc64le ppc64le   CPUs online: 160   CPUs total: 160   Page size: 65536   Pages avail: 1904339   Pages total: 2089666   Free space:   Filesystem Size Used Avail Use% Mounted on   udev 61G 0 61G 0% /dev   tmpfs 13G 12M 13G 1% /run   /dev/sda2 1.8T 11G 1.7T 1% /   tmpfs 64G 0 64G 0% /dev/shm   tmpfs 5.0M 0 5.0M 0% /run/lock   tmpfs 64G 0 64G 0% /sys/fs/cgroup   tmpfs 13G 0 13G 0% /run/user/1000   --------------------------------------------------------------------------------   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 2.31.1   /dev/nbd0: clean, 11/32768 files, 9787/131072 blocks   mount:   /dev/nbd0 on /mnt/nbd-test-13924 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-13924   creating large file /mnt/nbd-test-13924/largefile   -rw-r--r-- 1 root root 100M Mar 29 06:06 /mnt/nbd-test-13924/largefile   free:   Filesystem 1K-blocks Used Available Use% Mounted on   /dev/nbd0 122835 103951 9710 92% /mnt/nbd-test-13924   removing file /mnt/nbd-test-13924/largefile   unmounting /mnt/nbd-test-13924   stopping client   disconnect, sock, done   Found kernel warning, IO error and/or call trace   echo   [ 694.662746] creating backing nbd image /tmp/nbd_image.img   [ 695.821047] NBD device /dev/nbd0 created   [ 696.271555] found nbd export   [ 697.318393] starting client with NBD device /dev/nbd0   [ 697.323210] creating ext4 on /dev/nbd0   [ 697.589620] mkfs on /dev/nbd0 succeeded after 0 attempt(s)   [ 697.821953] checking ext4 on /dev/nbd0   [ 697.919173] EXT4-fs (nbd0): mounted filesystem with ordered data mode.

The fix is to ensure a rescan occurs. [Fix] Upstream fix fe1f9e6659ca6124f500a0f829202c7c902fab0c (" nbd: fix how we set bd_invalidated"). If a disconnect action happens the partition table gets invalidated and rescanned properly. [Test] Without the fix running the Ubuntu Kernel Team nbd smoke test will occasionally trip the bug and the error message from the kernel appears and the test fails. With the fix, this test has been run tens of times without showing the failure. To test run: autotest/client/local-test autotest/client/tests/ubuntu_nbd_smoke_test/control [Regression Potential] This fix touches just the NBD driver and has been upstream since May 2018 without any subsequent bug reports against it, so it is a known good fix. At most it sets the bd_invalidated flag more aggressively, so the rescan will occur, so I believe the regression potential is very limited just to ndb client connect/disconnect activity. --------- Reproduce rate: 2 out of 3 runs This issue can be found on other arches as well, normally it will fail with the first run and pass with the second attempt.   * Command:       /home/ubuntu/autotest/client/tests/ubuntu_nbd_smoke_test/ubuntu_nbd_smoke       _test.sh   Exit status: 1   Duration: 7.90551400185   stdout:   creating backing nbd image /tmp/nbd_image.img   --------------------------------------------------------------------------------   Image path: /tmp/nbd_image.img   Mount point: /mnt/nbd-test-13924   Date: Fri Mar 29 06:06:04 UTC 2019   Host: baltar   Kernel: 4.15.0-46-generic #49-Ubuntu SMP Wed Feb 6 09:32:48 UTC 2019   Machine: baltar ppc64le ppc64le   CPUs online: 160   CPUs total: 160   Page size: 65536   Pages avail: 1904339   Pages total: 2089666   Free space:   Filesystem Size Used Avail Use% Mounted on   udev 61G 0 61G 0% /dev   tmpfs 13G 12M 13G 1% /run   /dev/sda2 1.8T 11G 1.7T 1% /   tmpfs 64G 0 64G 0% /dev/shm   tmpfs 5.0M 0 5.0M 0% /run/lock   tmpfs 64G 0 64G 0% /sys/fs/cgroup   tmpfs 13G 0 13G 0% /run/user/1000   --------------------------------------------------------------------------------   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 2.31.1   /dev/nbd0: clean, 11/32768 files, 9787/131072 blocks   mount:   /dev/nbd0 on /mnt/nbd-test-13924 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-13924   creating large file /mnt/nbd-test-13924/largefile   -rw-r--r-- 1 root root 100M Mar 29 06:06 /mnt/nbd-test-13924/largefile   free:   Filesystem 1K-blocks Used Available Use% Mounted on   /dev/nbd0 122835 103951 9710 92% /mnt/nbd-test-13924   removing file /mnt/nbd-test-13924/largefile   unmounting /mnt/nbd-test-13924   stopping client   disconnect, sock, done   Found kernel warning, IO error and/or call trace   echo   [ 694.662746] creating backing nbd image /tmp/nbd_image.img   [ 695.821047] NBD device /dev/nbd0 created   [ 696.271555] found nbd export   [ 697.318393] starting client with NBD device /dev/nbd0   [ 697.323210] creating ext4 on /dev/nbd0   [ 697.589620] mkfs on /dev/nbd0 succeeded after 0 attempt(s)   [ 697.821953] checking ext4 on /dev/nbd0   [ 697.919173] EXT4-fs (nbd0): mounted filesystem with ordered data mode.
