Package: zfs-dkms Version: 0.8.6-1~bpo10+1 Severity: important Dear Maintainer,
* What led up to the situation? The kernel in stretch-backports was updated from 5.9.0-0.bpo.5-amd64 to 5.10.0-0.bpo.3-amd64. After rebooting, I was dropped to the initramfs rescue shell because my ZFS root file system could not be mounted. * What exactly did you do (or not do) that was effective (or ineffective)? The last time this has happened, the zfs-dkms module build did not run automaticalls and thus the zfs modules were missing from the initrd. I have since fixed this by setting REMAKE_INITRD='yes' in /etc/dkms/zfs.conf, but my first guess was that it has somehow gone wrong again. So I booted up the previous kernel (really grateful for that option) and tried to do a manual install of zfs-dkms via $ dkms install -k 5.10.0-0.bpo.3-amd64 zfs/0.8.6 * What was the outcome of this action? The compilation of the module failed, which explains why the ZFS modules were not included in the initrd in the first place. Compilation log shows this as the source of the error: - - - 8< - - - CC [M] /var/lib/dkms/zfs/0.8.6/build/module/zfs/vdev_disk.o /var/lib/dkms/zfs/0.8.6/build/module/zfs/vdev_disk.c: In function ‘vdev_blkg_tryget’: /var/lib/dkms/zfs/0.8.6/build/module/zfs/vdev_disk.c:506:37: error: ‘struct percpu_ref’ has no member named ‘count’ rc = atomic_long_inc_not_zero(&ref->count); ^~ make[6]: *** [/usr/src/linux-headers-5.10.0-0.bpo.3-common/scripts/Makefile.build:284: /var/lib/dkms/zfs/0.8.6/build/module/zfs/vdev_disk.o] Error 1 - - - >8 - - - * What outcome did you expect instead? I had expected zfs-dkms to build without failure, update my initrd and be able to boot into the current stretch-backports kernel. Due to some issues with Intel onboard graphics, I need to use the newer backports kernel instead of the the original stretch kernel. btw: Is there any way I can tell the kernel installer or the initramfs creation to fail if the the ZFS module has not been compiled? -- System Information: Debian Release: 10.8 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.9.0-0.bpo.5-amd64 (SMP w/2 CPU cores) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=de_DE.utf-8, LC_CTYPE=de_DE.utf-8 (charmap=UTF-8), LANGUAGE=de_DE.utf-8 (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages zfs-dkms depends on: ii debconf [debconf-2.0] 1.5.71 ii dkms 2.6.1-4 ii file 1:5.35-4+deb10u2 ii libc6-dev [libc-dev] 2.28-10 ii libpython3-stdlib 3.7.3-1 ii lsb-release 10.2019051400 ii perl 5.28.1-6+deb10u1 ii python3-distutils 3.7.3-1 Versions of packages zfs-dkms recommends: ii linux-libc-dev 4.19.171-2 ii zfs-zed 0.8.6-1~bpo10+1 ii zfsutils-linux 0.8.6-1~bpo10+1 Versions of packages zfs-dkms suggests: pn debhelper <none> -- debconf information: zfs-dkms/stop-build-for-unknown-kernel: true * zfs-dkms/note-incompatible-licenses: zfs-dkms/stop-build-for-32bit-kernel: true
