Here is what i did. I think it took it after reboot.
Step 1, check filesystem for / .
ts7500:/proc# df -T
Filesystem Type 1K-blocks Used Available Use% Mounted on
tmpfs tmpfs 31444 4 31440 1% /lib/init/rw
udev tmpfs 10240 172 10068 2% /dev
tmpfs tmpfs 31444 0 31444 0% /dev/shm
rootfs rootfs 507748 382932 98602 80% /
/dev/root ext2 1979 1784 195 91% /initrd
/dev/ram1 ext3 2971 1171 1647 42% /ramazu
Step 2: add noatime at /etc/fstab. As an experiment,
I add ext3 as file system
ts7500:/var/log# cat /etc/fstab
# UNCONFIGURED FSTAB FOR BASE SYSTEM
rootfs / ext3 defaults,noatime 0 0
Step 3 I reboot the linux. It shows the following.
rootfs has noatime
ts7500:~# mount
rootfs on / type ext3 (rw,noatime)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
udev on /dev type tmpfs (rw,mode=0755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)
/dev/root on /initrd type ext2 (rw)
/dev/ram1 on /ramazu type ext3 (rw)
For curiosity, at /ect/fstab, I used ext2 instead of ext3.
And it seems now roofs is ext2 noatime?
I am wondering if "rootfs / ext2 defaults,noatime 0 0" changed the fyilesystem
from ext3 to ext2 ???
See below.
ts7500:/var/log# cat /etc/fstab
# UNCONFIGURED FSTAB FOR BASE SYSTEM
rootfs / ext2 defaults,noatime 0 0
ts7500:/var/log# mount
rootfs on / type ext2 (rw,noatime)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
udev on /dev type tmpfs (rw,mode=0755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)
/dev/root on /initrd type ext2 (rw)
/dev/ram1 on /ramazu type ext3 (rw)
