Tested on Xenial, the degraded mount is failing on it as expected. # mount -o degraded $DEV0 $MNT mount: wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error
In some cases useful info is found in syslog - try dmesg | tail or so. The following operation will need the $MNT to be mounted: # btrfs balance start -f -sconvert=single -mconvert=single -dconvert=single $MNT ERROR: not a btrfs filesystem: /tmp/mnt-111 So for this test, we should: 1. Disable it on Xenial, unless it got 4330e183 landed 2.

However it is clear that we cannot do anything on missing device, and also it is not necessary to care chunks on the missing device. This patch stops sending/waiting barrier if device is missing. failed: degraded mount should have failed, but didn't FAIL: f88ba6a2a44ee98e8d59654463dc157bb6d13c43 (ret=1) 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 10:11 seq crw-rw---- 1 root audio 116, 33 Dec 27 10:11 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: CurrentDmesg: [ 29.063592] random: nonblocking pool is initialized Date: Thu Dec 27 10:11:58 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=2a4b0342-a2dd-4feb-b3e2-9644ca1c4a60 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/1809886/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
