cman was actually truncating the node when it looked for unqualified names, so the nodeid lookup failed later on in the search - that explains the rather odd error you got. This checkin simple uses the length returned from strstr rather than truncating the string at that point. (note: does this need to go into RHEL50 ?? ) HEAD: Checking in cmanccs.c; /cvs/cluster/cluster/cman/daemon/cmanccs.c,v <-- cmanccs.c new revision: 1.22; previous revision: 1.21 done -rRHEL5: Checking in cmanccs.c; /cvs/cluster/cluster/cman/daemon/cmanccs.c,v <-- cmanccs.c new revision: 1.21.2.1; previous revision: 1.21 done (note: does this need to go into RHEL50 ?? ) I'd say yes - if I didn't know the history of other bugs (now resolved) with luci and short-host names, I wouldn't have known how to approach debugging this. This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux major release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion. Checked in for RHEL50 Checking in cmanccs.c; /cvs/cluster/cluster/cman/daemon/cmanccs.c,v <-- cmanccs.c new revision: 1.21.4.1; previous revision: 1.21 done Verified bug fix in cman-2.0.52-1.el5 A package has been built which should help the problem described in this bug report. This report is therefore being closed with a resolution of CURRENTRELEASE. You may reopen this bug report if the solution does not work for you. Moving all RHCS ver 5 bugs to RHEL 5 so we can remove RHCS v5 which never existed. |
Description of problem: cman fails to start with short hostname set and fully qualified hostname in cluster.conf I found this inadvertently during some Conga testing. It looks as though if a cluster node's host name is defined without its domain, but the cluster.conf file includes the fully qualified host name - which is the only way that the Conga/luci web app will generate the file - cman cannot start. See below for additional information and an strace. Version-Release number of selected component (if applicable): cman-2.0.35-2.el5 How reproducible: 100% Steps to Reproduce: 1. Create a cluster via Conga - have the cluster nodes configured with short - not fully qualified hostnames. Actual results: cman fails to start Expected results: cman should start Additional info: With hostname defined in /etc/sysconfig/network as: ================================ NETWORKING=yes NETWORKING_IPV6=yes HOSTNAME=tng3-2 ================================ And reported by hostname/uname -n as: ================================ tng3-2 ================================ And with this cluster definition: ================================ <?xml version="1.0"?> <cluster alias="nodes23" config_version="1" name="nodes23"> <fence_daemon post_fail_delay="0" post_join_delay="3"/> <clusternodes> <clusternode name="tng3-2.lab.msp.redhat.com" nodeid="1" votes="1"/> <clusternode name="tng3-3.lab.msp.redhat.com" nodeid="2" votes="1"/> </clusternodes> <cman expected_votes="1" two_node="1"/> <fencedevices/> <rm/> </cluster> ================================ cman-2.0.35-2.el5 fails to start - here's an strace: ================================ execve("/usr/sbin/cman_tool", ["/usr/sbin/cman_tool", "-t", "120", "-w", "join", "-c", "nodes23"], [/* 23 vars */]) = 0 brk(0) = 0x9287000 access("/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or directory) open("/etc/ld.so.cache", O_RDONLY) = 3 fstat64(3, {st_mode=S_IFREG|0644, st_size=31538, ...}) = 0 mmap2(NULL, 31538, PROT_READ, MAP_PRIVATE, 3, 0) = 0xb7fc4000 close(3) = 0 open("/lib/libc.so.6", O_RDONLY) = 3 read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0p`]\000"..., 512) = 512 fstat64(3, {st_mode=S_IFREG|0755, st_size=1577100, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7fc3000 mmap2(0x5c0000, 1299876, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 3, 0) = 0x5c0000 mmap2(0x6f8000, 12288, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 0x137) = 0x6f8000 mmap2(0x6fb000, 9636, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0x6fb000 close(3) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7fc2000 set_thread_area({entry_number:-1 -> 6, base_addr:0xb7fc26c0, limit:1048575, seg_32bit:1, contents:0, read_exec_only:0, limit_in_pages:1, seg_not_present:0, useable:1}) = 0 mprotect(0x6f8000, 8192, PROT_READ) = 0 mprotect(0x5b7000, 4096, PROT_READ) = 0 munmap(0xb7fc4000, 31538) = 0 rt_sigaction(SIGALRM, {0x8048ea0, [ALRM], SA_RESTART}, {SIG_DFL}, 8) = 0 alarm(120) = 0 brk(0) = 0x9287000 brk(0x92a8000) = 0x92a8000 getpid() = 3179 socket(PF_FILE, SOCK_STREAM, 0) = 3 connect(3, {sa_family=AF_FILE, path="/var/run/cluster/ccsd.sock"}, 110) = 0 write(3, "\1\0\0\0\3\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0", 20) = 20 read(3, "\1\0\0\0\3\0\0\0w\2\0\0\0\0\0\0\0\0\0\0", 20) = 20 close(3) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 3 connect(3, {sa_family=AF_FILE, path="/var/run/cluster/ccsd.sock"}, 110) = 0 write(3, "\2\0\0\0\0\0\0\0w\2\0\0\0\0\0\0\0\0\0\0", 20) = 20 read(3, "\2\0\0\0\0\0\0\0\377\377\377\377\0\0\0\0\0\0\0\0", 20) = 20 close(3) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 3 fcntl64(3, F_SETFD, FD_CLOEXEC) = 0 connect(3, {sa_family=AF_FILE, path="/var/run/cman_admin"}, 110) = -1 ENOENT (No such file or directory) close(3) = 0 pipe([3, 4]) = 0 fcntl64(4, F_SETFD, 0) = 0 clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0xb7fc2708) = 3180 --- SIGCHLD (Child exited) @ 0 (0) --- select(4, [3], NULL, NULL, {1, 0}) = 0 (Timeout) socket(PF_FILE, SOCK_STREAM, 0) = 5 fcntl64(5, F_SETFD, FD_CLOEXEC) = 0 connect(5, {sa_family=AF_FILE, path="/var/run/cman_admin"}, 110) = -1 ENOENT (No such file or directory) close(5) = 0 select(4, [3], NULL, NULL, {1, 0}) = 1 (in [3], left {0, 601000}) read(3, "CCS does not have a nodeid for t"..., 1024) = 105 write(2, "cman not started: CCS does not h"..., 93cman not started: CCS does not have a nodeid for this node, run 'ccs_tool addnodeids' to fix ) = 93 write(2, "/usr/sbin/cman_tool: ", 21/usr/sbin/cman_tool: ) = 21 write(2, "aisexec daemon didn\'t start\n", 28aisexec daemon didn't start ) = 28 exit_group(1) = ?
