This is a bit of a surpise. Am I understanding correctly that running postgresql or mysql on top of LVM negates any data reliability measures the DBMS might have in the event of an unexpected shutdown? I have several servers configured to run LVM on top of MD1 for the convenience of being able to add more space to a volume in the future. I didn't realize this was a reliability risk. :( _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
