noatime difference

Post by rjsrjs »

Hello Everyone:
Here is something I found that is interesting to me, maybe someone can explain out there in Linux Land.
I get the following information about my /dev/sda1 SSD laptop boot drive when I use the command "cat /proc/mounts" in the terminal. Thats what Mint put in when I installed Mint 19.1. System is working great with out an problems on my Lenovo T430 with 180GB SSD and 8 Gigs of memory

Code: Select all

/dev/sda1 / ext4 rw,relatime,errors=remount-ro,data=ordered 0 0
And I get the following in my fstab file.

Code: Select all

UUID=a693fde7-85d5-4704-8897-d24e6d447abb	/	ext4	errors=remount-ro	0	1
/swapfile	none	swap	sw	0	0
In the fstab file there is no mention of relatime and other things, but in cat /proc/mounts there is relatime. Is this correct? I thought both should be the same.

Just curious Thanks.

If you check the man page for mount
Since Linux 2.6.30, the kernel defaults to the behavior provided by this option (unless noatime was specified)
