When running this test, it will hang with Trusty and gets killed by the timeout setting (2h), this will cause the following test failed with /dev/loop0 mounted issue: Invoking test 9f03740a956d7ac6a1b8f8c455da6fa5cae11c22 fix 9f03740a956d7ac6a1b8f8c455da6fa5cae11c22 Btrfs: fix infinite path build loops in incremental send The send operation processes inodes by their ascending number, and assumes that any rename/move operation can be successfully performed (sent to the caller) once all previous inodes (those with a smaller inode number than the one we're currently processing) were processed. [ .... ] Even without this loop, the incremental send couldn't succeed, because it would attempt to send a rename/move operation for the lower inode before the highest inode number was renamed/move. This issue is easy to trigger with the following steps: $ mkfs.btrfs -f /dev/sdb3 $ mount /dev/sdb3 /mnt/btrfs $ mkdir -p /mnt/btrfs/a/b/c/d $ mkdir /mnt/btrfs/a/b/c2 $ btrfs subvol snapshot -r /mnt/btrfs /mnt/btrfs/snap1 $ mv /mnt/btrfs/a/b/c/d /mnt/btrfs/a/b/c2/d2 $ mv /mnt/btrfs/a/b/c /mnt/btrfs/a/b/c2/d2/cc $ btrfs subvol snapshot -r /mnt/btrfs /mnt/btrfs/snap2 $ btrfs send -p /mnt/btrfs/snap1 /mnt/btrfs/snap2 > /tmp/incremental.send Create a readonly snapshot of '/tmp/mnt-9f03740a956d7ac6a1b8f8c455da6fa5cae11c22/btrfs' in '/tmp/mnt-9f03740a956d7ac6a1b8f8c455da6fa5cae11c22/btrfs/snap1' Create a readonly snapshot of '/tmp/mnt-9f03740a956d7ac6a1b8f8c455da6fa5cae11c22/btrfs' in '/tmp/mnt-9f03740a956d7ac6a1b8f8c455da6fa5cae11c22/btrfs/snap2' At subvol /tmp/mnt-9f03740a956d7ac6a1b8f8c455da6fa5cae11c22/btrfs/snap2 Timer expired (7200 sec.), nuking pid 27517 ERROR ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: linux-image-3.13.0-164-generic 3.13.0-164.214 ProcVersionSignature: User Name 3.13.0-164.214-generic 3.13.11-ckt39 Uname: Linux 3.13.0-164-generic x86_64 AlsaDevices: total 0 crw-rw---- 1 root audio 116, 1 Dec 27 08:26 seq crw-rw---- 1 root audio 116, 33 Dec 27 08:26 timer AplayDevices: Error: [Errno 2] No such file or directory: 'aplay' ApportVersion: 2.14.1-0ubuntu3.29 Architecture: amd64 ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord' AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: Date: Thu Dec 27 09:21:07 2018 IwConfig: Error: [Errno 2] No such file or directory: 'iwconfig' Lsusb: Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub MachineType: QEMU Standard PC (i440FX + PIIX, 1996) PciMultimedia: ProcFB: 0 cirrusdrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.13.0-164-generic root=UUID=576666e8-9e7f-40ee-934e-f1dce18323e5 ro console=ttyS0,115200n8 RelatedPackageVersions: linux-restricted-modules-3.13.0-164-generic N/A linux-backports-modules-3.13.0-164-generic N/A linux-firmware 1.127.24 RfKill: Error: [Errno 2] No such file or directory: 'rfkill' SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 04/01/2014 dmi.bios.vendor: SeaBIOS dmi.bios.version: Ubuntu-1.8.2-1ubuntu1 dmi.chassis.type: 1 dmi.chassis.vendor: QEMU dmi.chassis.version: pc-i440fx-xenial dmi.modalias: dmi:bvnSeaBIOS:bvrUbuntu-1.8.2-1ubuntu1:bd04/01/2014:svnQEMU:pnStandardPC(i440FX+PIIX,1996):pvrpc-i440fx-xenial:cvnQEMU:ct1:cvrpc-i440fx-xenial: dmi.product.name: Standard PC (i440FX + PIIX, 1996) dmi.product.version: pc-i440fx-xenial dmi.sys.vendor: QEMU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1809879/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
