Re: [Linux-cluster] noatime

The main reason why performance improves with noatime (is the nodiratime flag supported?) is because it means no write happens for ever file read. That means no locking required, which is the main thing that slows down concurrent accesses. I don't know what the first-access issue might be, but noatime should help under heavy concurrent use.

Were you trying this for a specific reason? I tried noatime to see if I could
get a faster initial response time from the GFS volume. Every time I access
it, there is a long delay initially, then things are fine until the next

Hi all,

If I put in my fstab file:
/dev/sdc5               /home           gfs     noatime

Will it actually mount without atime? And how can I confirm this?
