Package: lvm2 Version: 2.03.02-1 Severity: important There are possibly 2 different bugs in here, please clone as needed.
This computer has multiple VGs and had last been updated on Dec 13 before I ran an update on Jan 13. After this update it wouldn't complete boot because one VG would not be activated due to system ID mismatch. It dropped me into a root/rescue shell where I had full access to lvm tools since the root filesystem was not in the affected VG. The affected VG is ancient and has moved between computers and disks. It has a system ID set from way back when (it includes a hostname I haven't used for possibly more than a decade) while the newer, unaffected VGs have blank system IDs. The system is configured to have no system ID (system_id_source = "none"). Bug 1: This has worked for all these years until the update, which rejects the VG with system ID without advance warning during package upgrade. Systems may become unbootable after upgrade if these VGs contain filesystems that are mounted in /etc/fstab. Bug 2: Overriding system IDs does not work. I have tried setting local/extra_system_ids as described in lvmsystemid(7) but this appears to have no effect whatsoever. I could neither access the VG nor use vgchange to clear its system ID, access was still rejected. I tried both setting the variable in /etc/lvmlocal.conf and on the command line, and confirmed with lvmconfig that the option is seen. The only way to get access was to set global/system_id_source = "lvmlocal" and set local/system_id to the affected VG's system ID. I found this thread on the debian-user list where someone else appears to have exactly the same problems: https://lists.debian.org/msgid-search/20190113161023.ge10...@zaphod.galacticempire.org.us -- System Information: Debian Release: buster/sid Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.19.0-1-amd64 (SMP w/8 CPU cores) 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 /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages lvm2 depends on: ii dmeventd 2:1.02.155-1 ii dmsetup 2:1.02.155-1 ii libaio1 0.3.111-1 ii libblkid1 2.33.1-0.1 ii libc6 2.28-5 ii libdevmapper-event1.02.1 2:1.02.155-1 ii libdevmapper1.02.1 2:1.02.155-1 ii libreadline5 5.2+dfsg-3+b2 ii libselinux1 2.8-1+b1 ii libsystemd0 240-4 ii libudev1 239-15 ii lsb-base 10.2018112800 Versions of packages lvm2 recommends: ii thin-provisioning-tools 0.7.6-2 lvm2 suggests no packages. -- Configuration Files: /etc/lvm/lvm.conf changed [not included] /etc/lvm/lvmlocal.conf changed [not included] -- no debconf information
