There is no need to specify noatime and nodiratime.Code:# /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda1 during installation UUID=2e19524f-b028-4ef3-93a5-bed6757708fc / ext4 defaults,noatime,nodiratime,discard,errors=remount-ro 0 1 # /DATA was on /dev/sdc1 during installation # UUID=3A2084D220849713 /DATA ntfs defaults,umask=007,gid=46 0 0 # /SSD2DATA was on /dev/sdb1 during installation UUID=de961735-1d84-4c72-8abe-fefa7b03a708 /SSD2DATA ext4 defaults,noatime,nodiratime,discard,errors=remount-ro 0 2 # /home was on /dev/sda2 during installation UUID=5a71aee7-cd8c-431f-bdc3-828bc40226b7 /home ext4 defaults,noatime,nodiratime,discard,errors=remount-ro 0 2 # swap was on /dev/sdc2 during installation UUID=c01746dc-7f90-40a6-9dda-324aecf9bdce none swap sw 0 0 # Place tmp into ram tmpfs /tmp tmpfs defaults,mode=1777 0 0 tmpfs /var/tmp tmpfs defaults,mode=1777 0 0 tmpfs /var/spool tmpfs defaults,mode=1777 0 0 tmpfs /var/cache tmpfs defaults 0 0
Just using noatime implicitly specifies nodiratime as well.
