recently i've updated my server to the latest lvm2 version, where device-mapper was unmerged. I've also updated to the latest stable kernel. Since i'm using lvm2 (my system partition is on a lvm volume) i've also created a new initramfs. Booting the systm works quite fine. But now a facing a problem that everytime i'll make a backup (its a script which runs via cron) dmeventd crashs with the following massage: tunafix ~ # lvcreate --size 20G --snapshot --name test /dev/vg/system Unable to read from event server. vg-test: event registration failed: Eingabe-/Ausgabefehler vg/snapshot0: snapshot segment monitoring function failed. Logical volume "test" created also in dmesg i'll get a segmation fault: dmeventd[2072]: segfault at 0 ip 00007f2cd8935e8c sp 00007fff5d830dd8 error 4 in libdevmapper-event-lvm2snapshot.so.2.02[7f2cd8935000+2000] Actually it looks like the snapshot is created, because i still get weekley backups. (if i look into the tar files, everything looks ok). I don't know in how far this crash impact my backups... Reproducible: Always Steps to Reproduce: 1. update to the latest stable lvm2 packages 2. try to make a snapshot via: lvcreate --size 20G --snapshot --name test /dev/vg/system Actual Results: snapshot will be created, but dmeventd crashs Expected Results: dmeventd shouldn't crash emerge --info Portage 2.1.6.13 (default/linux/amd64/10.0/no-multilib, gcc-4.3.4, glibc-2.9_p20081201-r2, 2.6.31-gentoo-r6 x86_64) ================================================================= System uname: Linux-2.6.31-gentoo-r6-x86_64-Intel-R-_Xeon-R-_CPU_E5405_@_2.00GHz-with-gentoo-2.0.1 Timestamp of tree: Sat, 02 Jan 2010 05:15:01 +0000 app-shells/bash: 4.0_p35 dev-lang/python: 2.6.4 sys-apps/baselayout: 2.0.1 sys-apps/openrc: 0.6.0 sys-apps/sandbox: 1.6-r2 sys-devel/autoconf: 2.63-r1 sys-devel/automake: 1.9.6-r2, 1.10.2 sys-devel/binutils: 2.18-r3 sys-devel/gcc-config: 1.4.1 sys-devel/libtool: 2.2.6b virtual/os-headers: 2.6.29 ACCEPT_KEYWORDS="amd64" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-O2 -pipe -march=nocona -msse4.1" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo /etc/udev/rules.d" CXXFLAGS="-O2 -pipe -march=nocona -msse4.1" DISTDIR="/usr/portage/distfiles" FEATURES="distlocks fixpackages parallel-fetch protect-owned sandbox sfperms strict unmerge-orphans userfetch" GENTOO_MIRRORS=" http://gentoo.supp.name/ http://ftp.fi.muni.cz/pub/linux/gentoo/ http://gentoo.mirror.web4u.cz/ http://gentoo.mirror.dkm.cz/pub/gentoo/ http://gentoo.ynet.sk/pub" LANG="de_DE.utf8" LDFLAGS="-Wl,-O1" LINGUAS="de" MAKEOPTS="-j9" PKGDIR="/usr/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp/tunafix" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/home/clown/overlays/local /home/clown/overlays/layman/x11 /home/clown/overlays/layman/sunrise" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage/" USE="acl acpi amd64 berkdb bzip2 cli cracklib crypt cups cxx dbus dri fortran gdbm gpm iconv ipv6 mmx modules mudflap ncurses nls nptl nptlonly openmp pam pcre perl pppd python readline reflection session spl sse sse2 ssl ssse3 sysfs tcpd unicode xorg zlib" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" DVB_CARDS="ttpci" ELIBC="glibc" INPUT_DEVICES="keyboard mouse evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="de" RUBY_TARGETS="ruby18" USERLAND="GNU" VIDEO_CARDS="fbdev glint intel mach64 mga neomagic nv r128 radeon savage sis tdfx trident vesa via vmware voodoo" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, FFLAGS, INSTALL_MASK, LC_ALL, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS
