Hello, I run into the same problems with vservers, drbd and heartbeat as Martin in this thread: (devices remain busy after stopping vservers) http://www.paul.sladen.org/vserver/archives/200607/0132.html
I tried the elegant namespace-cleanup solution suggested by Daniel Hokka Zakrisson in: http://www.paul.sladen.org/vserver/archives/200607/0133.html http://www.paul.sladen.org/vserver/archives/200607/0173.html but now my vservers fail to startup with: save_ctxinfo: open("/var/run/vservers/testsrv"): No such file or directory An error occured while executing the vserver startup sequence; when there are no other messages, it is very likely that the init-script (/etc/init.d/rc 3) failed. Removing the namespace-cleanup flag in /etc/vservers/.defaults fixes the startup problem. starting with vserver --debug and strace'ing save_ctxinfo gives: ++ for i in '"$base/$flavor"' '"$base/$flavor.d"/*' ++ isRegularFile '/etc/vservers/.defaults/scripts/pre-start.d/*' ++ test -f '/etc/vservers/.defaults/scripts/pre-start.d/*' ++ return 1 ++ continue ++ test -z '' -o -n '' ++ popd ++ test -z '' ++ pushd /etc/vservers/testsrv/vdir/ ++ is_configured=1 ++ /usr/sbin/vserver-info - FEATURE migrate ++ /usr/bin/nice -n 0 /usr/sbin/chbind --silent --ip 10.10.10.40 -- /usr/lib/util-vserver/exec-ulimit /etc/vservers/testsrv/ulimits /usr/sbin/vcontext --create --silent -- /usr/sbin/vnamespace --set -- /usr/sbin/vlimit --dir /etc/vservers/testsrv/rlimits --missingok -- /usr/sbin/vsched --xid self -- /usr/sbin/vuname --xid self --dir /etc/vservers/testsrv/uts --missingok -- /usr/sbin/vuname --xid self --set -t context=/etc/vservers/testsrv -- /usr/sbin/vattribute --set --secure --flag default --flag fakeinit --flag sched_prio -- /usr/lib/util-vserver/save_ctxinfo /etc/vservers/testsrv /usr/bin/env -i -- /usr/sbin/vcontext --migrate-self --endsetup --chroot --silent --vlogin -- /etc/init.d/rc 3 execve("/usr/lib/util-vserver/save_ctxinfo.exe", ["/usr/lib/util-vserver/save_ctxin"..., "/etc/vservers/testsrv", "/usr/bin/env", "-i", "--", "/usr/sbin/vcontext", "--migrate-self", "--endsetup", "--chroot", "--silent", "--vlogin", "--", "/etc/init.d/rc", "3"], [/* 24 vars */]) = 0 vserver(0x2e010000, 0, 0, 0, 0xbfb1f612) = 49163 readlink("/etc/vservers/testsrv/run", "/var/run/vservers/testsrv", 4094) = 25 open("/var/run/vservers/testsrv", O_WRONLY|O_CREAT|O_EXCL|O_LARGEFILE, 0644) = -1 ENOENT (No such file or directory) write(2, "save_ctxinfo: ", 14save_ctxinfo: ) = 14 write(2, "open(\"/var/run/vservers/testsrv\""..., 33open("/var/run/vservers/testsrv")) = 33 write(2, ": ", 2: ) = 2 write(2, "No such file or directory", 25No such file or directory) = 25 write(2, "\n", 1 ) = 1 _exit(255) = ? ++ is_executed=1 ++ popd ++ pushd /etc/vservers/testsrv/vdir/ ++ execScriptlets /etc/vservers/testsrv testsrv post-start ++ declare -r vdir=/etc/vservers/testsrv ++ declare -r name=testsrv ++ declare -r flavor=post-start ++ local base i ++ for base in '"$vdir"/scripts' '"$__CONFDIR"/.defaults/scripts' open("/var/run/vservers/testsrv", O_WRONLY|O_CREAT|O_EXCL|O_LARGEFILE, 0644) fails ? When strace'ing without namespace-cleanup the same call works without problems. The problem exists on both i386 and amd64 kernels and util-vserver Has anybody some suggestions how I could narrow down this problem ?
