gparted/kde not starting
« on: 2014/09/02, 14:03:15 »
Hi,


gparted under KDE crashes before drives are shown. no errors are prompted in the terminal.
Any suggestions?


I started gparted from the terminal via sux.


btw, what does this mean:


Code: [Select]
sux
Passwort:
bash: Kann die Prozessgruppe des Terminals nicht setzen (-1).: Unpassender IOCTL (I/O-Control) für das Gerät
bash: Keine Job Steuerung in dieser Shell.


Code: [Select]
apt-cache policy gparted
gparted:
  Installiert:           0.19.0-1+b1
  Installationskandidat: 0.19.0-1+b1

Cheers
Mathias

I bet: You start it a second time, and it will not crash. This is how it "works" here. Don't know why.

Ahm, if I recall correctly, sux is broken, use kdesu/gksu instead, depending on your DE.
Ok, you can't code, but you still might be able to write a bug report for Debian's sake

Right, sux is broken and will most probably never be fixed. There is suxterm, which works still.

thanks. gparted starts now without problems.


but, when i am trying to format a 4 TB WD Elements external drive gparted still crashes while scanning the drive. the drive is formatted with ntfs and i can use it out of the box. but i want to format it with ext4.

i know, i can use fdisk (or maybe not since fdisk can only write partitions up to 2 TB), but i've never had any problems with gparted so far.


any suggestions what might be the problem and/or how can i format the 4 TB partition?

Yes, here are 2:


(1) Use a bootable Parted Magic live cd/usb stick, or


(2) Use mkfs.ext4 at the command line.   ;)

hi,


(1) maybe i try parted magic, but since it is based on gparted it might also crash




i tried to check the partition table with parted


Code: [Select]
parted /dev/sdc
GNU Parted 3.2
Using /dev/sdc

then i tried



Code: [Select]

file -s /dev/sdc
/dev/sdc: DOS/MBR boot sector


now i am not sure, if i can just run


(2) mkfs.ext4


since i thought i have to use the GUID Partition Table (GPT) for partitions larger than 2TB. On the other hand, i dont know how the drive has been formatted with ntfs to 4TB and dos/mbr.

Strange -- I googled that error and the first page of hits were all from 2006 - 2009.  It seems they were trying to overcome the hard-coded 512 byte sector size.  But I didn't see a recent hit.  I haven't yet worked with a hdd >2GB, so I dunno.  I would still try the Parted Magic Live stick, although he now charges a small fee for the ISO download.  I have relied on that for years to work with hard drives.

Correct -- those are common now -- I have 2 hdds with 4096-byte sectors.  But current (G)Parted should not have any problem with them just because of the sector size.  There must be something else in your case.

Hello hypper,

you need GPT partitioning for disks > 2TB and  fdisk isn't capable. Use gdisk instead.
GPT uses a protective pseudo MBR that claims "disk full, no free space left" to prevent use of old tools like fdisk.

I still can't explain why gparted segfaults with your disk. It should™ work -- at least in theory.

In my KDE system i can start gparted directly from the menu - and policykit will ask for root rights.
I attached a screenshot.

greetings
