Hi There,

Just wondering if there are any known issues with using the noatime flag for mounting via fstab?

Has anyone done this?
Did it provide any measurable benefit?
Did it cause any issues?

Thanks.

Hello,

From a quick bit of research, this sounds like there is no major issue, only 'mutt' an email client that relied on atime.


By the sounds of this, it is safe and can provide a good amount of improvement.

Hey there,

Most people do not configure this since it is not the default. Our tuning guide filesystem linked below does recommend its use.

We have done this in the past on /tmp file systems (for example) as it aided some backup software that we used to use. No side effects other than it sped up the backup software.
