Hi, stackers, Following the config tutorial (http://docs.openstack.org/trunk/openstack-config/content/drive-audit-conf.html), I create a drive_audit.conf file: [drive-audit] device_dir = /srv/node log_facility = LOG_LOCAL0 log_level = INFO minutes = 60 error_limit = 1 log_file_pattern = /var/log/kern* regex_pattern_1 = \berror\b.*\b(dm-[0-9]{1,2}\d?)\b Can anyone give me some log examples in kernal.log which means drive failure so I can test whether the swift-drive-audit works? Thanks a lot. Best Regards Jonathan Lu
