Hi,
for me it seems that qdiskd cannot successfully register in cman.
I think I found the reason for your problem in the source (libcman.c):
#define MAX_CLUSTER_NAME_LEN 16
...
int cman_register_quorum_device(cman_handle_t handle, char *name, int
votes)
{
struct cman_handle *h = (struct cman_handle *)handle;
char buf[strlen(name)+1 + sizeof(int)];
VALIDATE_HANDLE(h);
if (strlen(name) > MAX_CLUSTER_NAME_LEN)
{
errno = EINVAL;
return -1;
}
memcpy(buf, &votes, sizeof(int));
strcpy(buf+sizeof(int), name);
return info_call(h, CMAN_CMD_REG_QUORUMDEV, buf,
strlen(name)+sizeof(int), NULL, 0);
}
==> try using a shorter qdiskd device name than
"/dev/mpath/1HITACHI_750403220023p1" (< 16 chars).
Regards,
Robert

Subject: [Linux-cluster] qdisk votes not in cman
I have a cluster running RHEL5 U1 beta with two nodes and a quorum disk
(at least it's in the cluster.conf file). However, when I run cman_tool
nodes and cman_tool status, I don't see the qdisk votes represented.
I've confirmed that qdiskd is indeed running. I'd appreciate it if
someone could help point me to my mistake here.
Thanks in advance.
