I read someplace that you can reduce wear and tear on hard drives by including noatime in the mount options. I already do this for the one system I have using a CF card, but I was wondering about it just in general. I have several servers that rsync themselves various places for backups. That means that every time I rsync the entire filesystem, a gazillion atimes are being updated for essentially no reason. Ditto for the s/locate indexer. I can't recall ever using an atime for anything (ctime and mtime yes, atime no). Can anyone give me a good reason not to do this on some/all of my machines? All of my machines are ext3, some have H/W EIDE RAID, others have software (MDM) mirroring, some are just plain old hard drives, if it matters. Most are Debian or Ubuntu but I have a couple of CentOS4 boxes too. And what about for machines in a VM?
