SSD set up assistance please? (solved)

[Wompoo]

I am stuck at point #7 in this set of instructions on optimizing my new SSD:
https://sites.google.com/site/easylinuxtipsproject/ssd

Specifically this part (c) here:

"c. Now add the word noatime to the line for your root partition and your other Linux partitions, just before errors=remount-ro. Note: don't add it to the line for the swap partition!
Here's an example of an adapted line, in which you can see the exact spot where the noatime switch has to be put:
UUID=xxxxxxx / ext4 noatime,errors=remount-ro 0 1"

Will someone interpret the above for this beginner please?

Will someone interpret the above for this beginner please?

In a terminal:

Code: Select all

sudo nano -w /etc/fstab

Navigate to the line that mounts your / (root) system, for example:

UUID=65654675476AE53 / ext4 errors=remount-ro 0 0"

Navigate to e in errors and type noatime,

Don't forget the comma, and don't include spaces. Your cursor should be over the e when you start to type.

ctrl-o + <enter> to save, ctrl-x to exit.

Before you do that, backup fstab:

Code: Select all

sudo cp /etc/fstab /etc/fstab.bak

If you can't boot after making the change, use ctrl-F1 to start a terminal and issue these commands:

Code: Select all

sudo cp /etc/fstab.bak /etc/fstab
sudo reboot

Thanks for the prompt reply Catweazel.
I think I have it. Is this the terminal entry that I now enter after typing in noatime:


# /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>
# / was on /dev/sda1 during installation
UUID=ae6b558b-c19e-4df1-b053-98ca844b75f1 / ext4 noatime,errors=remount$
# swap was on /dev/sda5 during installation
UUID=8ff79968-3597-4632-a6e3-a002242b9909 none swap sw 0 $

But:

Should I go out of that and enter the fstab update command first? Then do the above?

edit: I have now done the backup entry.

That looks almost right. I don't recognise the $ symbol in errors=remount$. Maybe the text got cut off. Anyway, noatime, is in the right place and in the right format. You're good to go.

Cheers.

All good then Catweazel, thanks again.

[Wompoo]

oopps! I must have done something wrong.


Please ignore - wrong command entered!

All good then Catweazel, thanks again.

You're most welcome.

I selected all of the terminal result, copy and pasted to word file and saved in documents.
Is that what was meant by "save the modified text file"?

edit:
I found the save option in the terminal options at the top. Done.
However, when I go to close the terminal, it warns that a process is still running. What do I do now?

I didn't read all of Pjotr's instructions so I don't know, sorry.

No Problem catweazel.

Someone else came to my rescue using TeamViewer.
Thanks for your replies and assistance.
I will mark this as solved.
