Yes, that's right (except you left the 6th field, the pass order, off from the end of the edited line). > From: Matt Black [mailto:matt.bl...@jbadigital.com] >> In order to fix this you will need to update /etc/fstab and reboot. On any recent linux and ext3/4 combination (I'm not sure about XFS and friends) you don't need to reboot for this to take effect: % mount | head -n1 /dev/mapper/vg-root on / type ext4 (rw) % sudo mount -o remount,noatime / % mount | head -n1 /dev/mapper/vg-root on / type ext4 (rw,noatime) Obviously you still need to update /etc/fstab for this to persist across reboots. This is just a performance improvement (not writing access times to every file), so if you're not that fussed about performance you might as well leave atime enabled on your root disk. If you are fussed about performance, you should probably have your Riak data on a separate filesystem anyway (which can then be mounted with noatime and whatever other performance tuning options you'd like).
