Disabling ZFS atime

[dennylin93]

Hi, I'm in the process of setting up a new server with ZFS. Right now, I plan to use ZFS for MySQL and the mail storage. Is it safe to disable atime on these directories? I seem to remember that some parts of the system require atime to function correctly (like logs), so I'm not sure if it's ok to turn it off.

I believe you are mistaken, it is absolutely safe to turn off atime.

I have noatime on everything, including /var (which includes /var/log here), and I don't see any issues with the logfiles or syslog in general, or any other process. That's on regular UFS2 though.

Thanks. I'll try it out today.
