Package: lvm2 Version: 2.02.95-8 Severity: critical Justification: breaks the whole system
Dear Maintainer, When using a btfrs for the root if without the first device being on lvm, but with other devices used in the file system whichi are on lvm then the initscript decicded not to make the vg availble . Since in thise case all the devices which make up the root filesystem are not availabel it cannot be mounted rendering the system unbootable. I have looked at the existing bugs filed against ths package such as #566965 , an it looks like failure to make VG available is common in a number of disparate circumstances. Can I suggest a cmdline argument is added (tested for) to force this to occurs so it can be easily fixed / forced by the user. Having to manually edit you initrd scripts for a specicifc filesystem layout is mor complicated than (IMHO) it should be. Adding a simpl way of forcing this allow the complicated setups to work with minimal impact on the simpler ones. This patch is an example of what I suggest. --- /usr/share/initramfs-tools/scripts/local-top/lvm2 2009-08-17 18:28:09.000000000 +0100 +++ lvm2 2014-11-15 16:21:22.646647766 +0000 @@ -60,7 +60,11 @@ modprobe -q dm-mod -activate_vg "$ROOT" -activate_vg "$resume" +if grep force_lvm /proc/cmdline > /dev/null; then + lvm vgchange -aly --ignorelockingfailure ; +else + activate_vg "$ROOT" + activate_vg "$resume" +fi exit 0 Under btrfs, this is a particularly insidious problem as growing the root filesystem can trigger it , on and otherwise working system, and even if you remember to update you initramfs, you are still left with a unbootbale system. I don't believe this script has changed between wheezy and jessie so I suspect it affects Jessie as well. I can confirm that my system boots file with this patch and the force_lvm parameter on the kernel cmdline. -- System Information: Debian Release: 7.4 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 3.2.0-4-amd64 (SMP w/1 CPU core) Locale: LANG=C, LC_CTYPE=C (charmap=UTF-8) (ignored: LC_ALL set to en_GB.UTF8) Shell: /bin/sh linked to /bin/dash Versions of packages lvm2 depends on: ii dmsetup 2:1.02.77-1 ii initscripts 2.88dsf-41+deb7u1 ii libc6 2.17-3 ii libdevmapper-event1.02.1 2:1.02.77-1 ii libdevmapper1.02.1 2:1.02.77-1 ii libreadline5 5.2+dfsg-2 ii libudev0 175-7.2 ii lsb-base 4.1+Debian8+deb7u1 lvm2 recommends no packages. lvm2 suggests no packages. -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
