dlm and gfs2 in 2.6.20 have many problems, first of all dlm_send and dlm_recv eats all the cpu when one clustered service is active (gfs,clvmd and so on) Reproducible: Always Steps to Reproduce: 1. boot with a 2.6.20 kernel 2. enable cman 2.0x.xx 3. start something like clvm, gfs ... 4. cpu goes to 100% Actual Results: cpu 100% Expected Results: normal cpu load Portage 2.1.4.4 (default-linux/x86/no-nptl, gcc-4.1.2, glibc-2.5-r4, 2.6.20-xen-r6 i686) ================================================================= System uname: 2.6.20-xen-r6 i686 Dual-Core AMD Opteron(tm) Processor 2216 Timestamp of tree: Sun, 17 Feb 2008 17:46:01 +0000 ccache version 2.4 [enabled] app-shells/bash: 3.2_p17-r1 dev-lang/python: 2.4.4-r6 dev-python/pycrypto: 2.0.1-r6 dev-util/ccache: 2.4-r7 sys-apps/baselayout: 1.12.10-r5 sys-apps/sandbox: 1.2.18.1-r2 sys-devel/autoconf: 2.13, 2.61-r1 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10 sys-devel/binutils: 2.18-r1 sys-devel/gcc-config: 1.4.0-r4 sys-devel/libtool: 1.5.24 virtual/os-headers: 2.6.23-r3 ACCEPT_KEYWORDS="x86" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=i686 -pipe -fomit-frame-pointer -mno-tls-direct-seg-refs" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc" CONFIG_PROTECT_MASK="/etc/env.d /etc/gconf /etc/revdep-rebuild /etc/terminfo /etc/udev/rules.d" CXXFLAGS="-O2 -march=i686 -pipe -fomit-frame-pointer -mno-tls-direct-seg-refs" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs buildpkg ccache distlocks metadata-transfer sandbox sfperms strict unmerge-orphans userfetch" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/linux/distributions/gentoo" LINGUAS="it" MAKEOPTS="-j5" PKGDIR="/usr/portage/packages/xen-server" 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" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage" USE="apache2 apm berkdb bitmap-fonts cli cracklib crypt cups eds emboss encode foomaticdb fortran gdbm gif gpm gstreamer gtk2 iconv imlib isdnlog jpeg libwww mad mailwrapper midi mikmod motif mp3 mpeg mudflap ncurses nls ogg opengl openmp oss pam pcre perl png pppd python qt3 qt4 quicktime readline reflection sdl session spell spl ssl tcpd truetype truetype-fonts type1-fonts utf8 vhosts vorbis x86 xml xorg xv zlib" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1 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 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" ELIBC="glibc" INPUT_DEVICES="keyboard mouse" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="it" USERLAND="GNU" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS
Created attachment 143844 [details, diff] this patch backports many fixes from 2.6.21 that works as expected
Please add also patch in bug #210495 as I plan to release a gfs-kernel ebuild that works also with a xen 2.6.20x kernel
Christian, what's the status of this bug from your side? Is there a necessity to backport to 2.6.20 and not use 2.6.21 ? How does 2.6.18 do for you?
Dropped version. Try .29 or .31 :)
