[SOLVED] How do I increase the size of an existing GPT ext4 partition?

I found some advice here
http://ubuntuforums.org/showthread.php?t=1389429
but I'm not sure whether the information is correct
1 Run parted on your device: parted /dev/sdX
2 Change display unit to sectors: unit s
3 Print current partition table and note the start sector for your partition: p
4 Delete your partition (won't delete the data or filesystem): rm <number>
5 Recreate the partition with the starting sector from above: mkpart primary <start> <end>
6 Exit parted: quit
7 Check the filesystem: sudo e2fsck -f /dev/sdXX
8 Resize filesystem: sudo resize2fs /dev/sdXX
I'd like to increase partition #2 from 200 Gig to 300 Gig using gnu parted.
(parted) p                                                               
Modell: ATA WDC WD15EARX-00Z (scsi)
Festplatte  /dev/sda:  1500GB
Sektorgröße (logisch/physisch): 512B/4096B
Partitionstabelle: gpt
Disk Flags:
Nummer  Anfang     Ende        Größe       Dateisystem  Name              Flags
1      2048s      25167871s   25165824s   ext4         Linux filesystem
2      25167872s  444598271s  419430400s  ext4
or with unit set to GiB:
Nummer  Anfang   Ende     Größe    Dateisystem  Name              Flags
1      0,00GiB  12,0GiB  12,0GiB  ext4         Linux filesystem
2      12,0GiB  212GiB   200GiB   ext4
What is the correct way for doing this?

From the wiki gparted topic:
GParted is a GTK+ frontend to GNU Parted and the official GNOME Partition Editor application.
I think gparted can do anything gnu parted can do. The warning about ext4 in the topic you linked is from 2009, and recommends using gparted with a version higher than 0.6.2-2. Gparted 0.14.0-1 is currently in the Arch repo, so I think it's probably safe.

  • How do I increase the size of the text on the toolbar?

    How do I increase the size of the toolbar text, please?  For some reason, it's now very tiny, and everything I do only increases the font size of whichever web sites I access (which is not what I'm wanting to accomplish). 
    Thanks in advance for any help in this. Actually, I'm wondering what I might have done that would make the toolbar so tiny?

    Do  you mean the menu bar at the very top of your screen?
    If so, open System Preferences > Displays > Display > Scaled
    Try a different resolution.

  • Apple Mail (Mavericks), Viewing size of list is too small.how do you increase the size of the email message list.  The font is too small, I can hardly read them.

    In Apple Mail, using Mavericks, how do you increase the size of the email message list that displays on the left side of the screen?
    The font size is so small.
    Thanks.

    Thank you for responding.  After investigating and checking further, it was clear that only one of your suggestions changes the font size of the list of emails, also called the In-box.  And that is the display resolution.
    However, changing the display resolution affects the dots per inch of everything, everywhere and makes it larger.
    Given the high end fee Apple charges for their products, and the generally well developed software they provide, it is hard to imagine they have not corrected this obvious slight of effort on the inbox text. At times Apple's "one-size-fits-all" and "it's our way or no way" mentality astounds me and makes me want to run back to Microsoft.
    Evidently this is a well known mistake, which has yet to receive any attention.
    Again, thank you for your effort and assistance on my behalf.

  • How can I increase the size of UI toolbars across Adobe Creative suite?

    How can I increase the size of UI toolbars across Adobe Creative suite especially indesign, photoshop, illustrator on a new Apple retina display 2560 x 1140 with out changing/scaleing my screen resolution down?

    While some applications let you change the font size of the UI (notably Photoshop in Interface Preferences), others do not yet (like InDesign).
    You'll need to make your request using this form for it to be seen by the product manager(s):
    Adobe - Feature Request/Bug Report Form
    Make a good case because there are hundreds (thousands?) of things people request InDesign to do.

    how do i increase the letter size on the screen

    I have vision issues and changing the desktop resolution on my 27-inch iMac from the default of 2560x1440 to 1920x1080 fixed the problem for me. Everything is still sharp, something that won't happen if you do control + scroll.

  • HOW DO I INCREASE THE SIZE O MY 7640 ALL IN ONE PRINTER

    HOW CAN I INCREASE MY FONT SIZE IN MY HP 7640 PRINTER

    Hello jrfirepup, and welcome to the HP Forums.
    I see you are looking into printhead options.  This particular model of printer has built-in printheads, making them non-removable.
    I would recommend removing the cartridges and performing a power reset.  Disconnect the power cord from the printer and the power outlet, then wait 60 seconds. After 60 seconds, plug the printer back in. Ensure you plug the printer directly to a wall outlet. Make sure to bypass any sort of surge protector or power bar.
    I would also suggest this document on Ink Smears or Streaks.
    Good luck and please let me know the results of your troubleshooting steps. Thank you for posting on the HP Forums.

  • How do I increase the size of fonts in Yosemite?

    Hey all, recently I’ve been struggling to read the system fonts on Yosemite. I need to squint in order to see texts. For example, the font at the top left of the screen where the ‘Apple logo’ is it’s hard for me to read the text. I’ve got a 21.5inch LED monitor.
    In Finder, I’ve increased the text size to 16, which is the highest number. How can I increase it beyond 16 size font?
