Title: gparted/kde not starting
Post by: hypper 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

Post by: michaa7 on 2014/09/02, 14:08:26: 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.

Post by: hypper on 2014/09/03, 13:20:31: 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. ;)

Post by: hypper on 2014/09/04, 12:53:36: 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 Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) print You found a bug in GNU Parted! Here's what you have to do: Don't panic!

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.

Error: SEGV_MAPERR (Address not mapped to object)

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.

it is a 4k sector size drive.

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.

Post by: musca on 2014/09/08, 04:00:30: 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
