oh, and forgot one a couple of years ago. - Bad interaction between ext3, software RAID (md), LVM, and the 2.4.20 kernel. Led to filesystem corruption. I suspect this was a bug that has since been fixed; but I don't believe I was the only one to be bitten by this. http://lkml.org/lkml/2003/1/5/11 http://lkml.org/lkml/2003/1/5/224 So all my real software problems with md may have been fixed by now; but I'm pretty soured on it by my experiences, and practical experience has demonstrated to me that 3ware hardware RAID is a better value proposition both for performance and maintenance (disk replacement speed) reasons. -- Carl Soderstrom Systems Administrator Real-Time Enterprises www.real-time.com ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
