--- Begin Message ---Package: bcache-tools Version: 1.0.7-1 Severity: grave Justification: renders package unusable Dear Maintainer, This morning, due to a resume failure, I discovered my system unbootable. I have root on a bcache array and initramfs was unable to find the array by uuid. # blkid /dev/bcache0 /dev/bcache0: LABEL="ROOT" UUID="99af68b8-58f6-4329-94a8-c54fbf0e9364" TYPE="ext4" # lsblk -o NAME,MAJ:MIN,RM,SIZE,TYPE,FSTYPE,MOUNTPOINT,UUID,PARTUUID NAME MAJ:MIN RM SIZE TYPE FSTYPE MOUNTPOINT UUID PARTUUID sda 8:0 0 238.5G disk ├─sda1 8:1 0 1.9G part ext4 /boot 3483abf0-06d1-43bb-8982-a472d290bae7 40579936-01 ├─sda2 8:2 0 1K part 40579936-02 ├─sda5 8:5 0 14.9G part swap [SWAP] 78e5304e-d5ad-486f-b3de-fc8e0022832c 40579936-05 ├─sda6 8:6 0 14.9G part ext4 /tmp 4dcf9f94-1fcd-470b-9867-222722add442 40579936-06 └─sda7 8:7 0 206.8G part bcache 81035a2f-26fc-4546-abae-90d79d2224e4 40579936-07 └─bcache0 254:0 0 1.8T disk ext4 / 99af68b8-58f6-4329-94a8-c54fbf0e9364 sdb 8:16 0 1.8T disk └─sdb1 8:17 0 1.8T part linux_raid_ 9d8dceb3-1e4d-9958-45a2-7efb6656bbff fed0dc65-01 └─md2 9:2 0 1.8T raid1 bcache 7ba33238-474f-4627-8654-78bf9e36049a └─bcache0 254:0 0 1.8T disk ext4 / 99af68b8-58f6-4329-94a8-c54fbf0e9364 sdc 8:32 0 1.8T disk └─sdc1 8:33 0 1.8T part linux_raid_ 9d8dceb3-1e4d-9958-45a2-7efb6656bbff 9b7690d0-01 └─md2 9:2 0 1.8T raid1 bcache 7ba33238-474f-4627-8654-78bf9e36049a └─bcache0 254:0 0 1.8T disk ext4 / 99af68b8-58f6-4329-94a8-c54fbf0e9364 Relevant entry in fstab is: UUID=99af68b8-58f6-4329-94a8-c54fbf0e9364 / ext4 errors=remount-ro 0 1 This previously worked without problem. However, I now find the bcache array missing in both /dev/disk/by-uuid and /dev/disk/by-label: # ls /dev/disk/by-uuid/ 3483abf0-06d1-43bb-8982-a472d290bae7 78e5304e-d5ad-486f-b3de-fc8e0022832c 81035a2f-26fc-4546-abae-90d79d2224e4 4dcf9f94-1fcd-470b-9867-222722add442 7ba33238-474f-4627-8654-78bf9e36049a # ls /dev/disk/by-label/ BOOT TMP Now the bcache module is correctly being added to the initramfs, and when initramfs barfs and drops me to a shell, both the underlying RAID and the bcache array are running just fine - I can directly mount and use the bcache array; i.e. it is not an issue with registration of devices in the bcache array, or missing modules or anything like that. Indeed, if in the initramfs shell I do a: # cd /dev/disk/by-uuid # ln -s ../../bcache0 99af68b8-58f6-4329-94a8-c54fbf0e9364 # exit then the system boots up normally. I therefore believe the issue is either in /lib/udev/probe-bcache or /lib/udev/rules.d/69-bcache.rules, both of which are in this package. Even when the system is fully booted, there is no correct entry in /dev/disk/by-uuid and /dev/disk/by-label (i.e. the problem is not just in initramfs). As a temporary work around, I have changed my fstab to use /dev/bcache0 rather than the UUID and set GRUB_DISABLE_LINUX_UUID=true in /etc/default/grub before running update-grub. This at least means my system can boot. Severity was chosen to be grave on the basis that this problem has stopped my system from being bootable in both normal and recovery mode, and I would guess would affect anyone using a bcache as their root. -- System Information: Debian Release: stretch/sid APT prefers testing-updates APT policy: (500, 'testing-updates'), (500, 'unstable'), (500, 'testing') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.0.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages bcache-tools depends on: ii initramfs-tools 0.120 ii libblkid1 2.26.2-5 ii libc6 2.19-18 ii libuuid1 2.26.2-5 bcache-tools recommends no packages. bcache-tools suggests no packages. -- no debconf information

(Closes: #787263) * Ignore test failures on mipsel; the three failures are not reproducible on the porter box (different kernel?). (See #787258) * Add ifupdown-hotplug autopkgtest.
