I store CIB and PE files to tmpfs, and sync them to remote storage (CIFS) with lsyncd level 1 config (I may share it on request). It copies critical data like cib.xml, and moves everything else, symlinking it to original place. The same technique may apply here, but with local fs instead of cifs. Btw, the following patch is needed for that, otherwise pacemaker overwrites remote files instead of creating new ones on tmpfs: --- a/lib/common/xml.c 2011-02-11 11:42:37.000000000 +0100 +++ b/lib/common/xml.c 2011-02-24 15:07:48.541870829 +0100 @@ -529,6 +529,8 @@ write_file(const char *string, const char *filename) return -1; } + unlink(filename); + file_output_strm = fopen(filename, "w"); if (file_output_strm == NULL) { crm_perror(LOG_ERR, "Cannot open %s for writing", filename); _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
