Ok, I have 4 production systems. There is one NTP server for all four systems. In each system there is one Solaris 10 box that points to that NTP server. All of the other machines in the system point to the Solaris 10 machine to get their time sync.
All four Solaris 10 machines have essentially... (2 Replies)

Hi,
I have two ntp servers in my cluster and I want all the nodes in my cluster to sync with either of the ntp servers or just one. Unfortunately it keep rotating the sync, between my ntp server 1, ntp server 2 and local. Is there anyway I can change the sync to avoid local?

SYNC(2) Linux Programmer's Manual SYNC(2)
NAME
sync, syncfs - commit filesystem caches to disk
SYNOPSIS
#include <unistd.h>
void sync(void);
int syncfs(int fd);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
sync():
_XOPEN_SOURCE >= 500
|| /* Since glibc 2.19: */ _DEFAULT_SOURCE
|| /* Glibc versions <= 2.19: */ _BSD_SOURCE
syncfs():
_GNU_SOURCE
DESCRIPTION
sync() causes all pending modifications to filesystem metadata and cached file data to be written to the underlying filesystems.
syncfs() is like sync(), but synchronizes just the filesystem containing file referred to by the open file descriptor fd.
RETURN VALUE
syncfs() returns 0 on success; on error, it returns -1 and sets errno to indicate the error.
ERRORS
sync() is always successful.
syncfs() can fail for at least the following reason:
EBADF fd is not a valid file descriptor.
VERSIONS
syncfs() first appeared in Linux 2.6.39; library support was added to glibc in version 2.14.
CONFORMING TO
sync(): POSIX.1-2001, POSIX.1-2008, SVr4, 4.3BSD.
syncfs() is Linux-specific.
NOTES
Since glibc 2.2.2, the Linux prototype for sync() is as listed above, following the various standards. In glibc 2.2.1 and earlier, it was
"int sync(void)", and sync() always returned 0.
According to the standard specification (e.g., POSIX.1-2001), sync() schedules the writes, but may return before the actual writing is
done. However Linux waits for I/O completions, and thus sync() or syncfs() provide the same guarantees as fsync called on every file in
the system or filesystem respectively.
BUGS
Before version 1.3.20 Linux did not wait for I/O to complete before returning.
