Topic: [SOLVED]Need Help Testing "Align to MiB", and sector sizes > 512 bytes

EDIT:  GParted 0.6.0 was released on June 18, 2010.

Would you like to help us build a better, more robust GParted?

We could use help testing partition operations:

  • on disk devices with sector sizes > 512 bytes.

  • on any disk device using the new default "Align to MiB" alignment.

Testing is advised on a non-production system when you have a backup of your data.  :-)

Initial support for devices with sector sizes > 512 bytes and partition alignment to the nearest Mebibyte (1,048,576 bytes) has been added to GParted and committed to the gnome git repository.

A tarball is available at:
gparted-0.6.0-beta1.tar.bz2 - No longer available.

EDIT 2010-06-11:  Updated tarball available for download
gparted-0.6.0-beta2.tar.bz2

EDIT 2010-06-16:  Thanks to Francois Dupoux, gparted-0.6.0-beta2 has been included on the System Rescue CD beta version.  You can download this Live CD at the following link:
SysRescCd-Beta-x86

Testing to date has been performed on disk devices with 512 byte sector sizes.   Testing with larger sector sizes has been performed using the SCSI_DEBUG device driver.

REQUIRED DEPENDENCIES:

  • libparted version 2.2 or higher is required for sector sizes larger than 512 bytes.

KNOWN ISSUES:

  • hfs/hfs+: used/unused space not detected when sector size > 512 bytes

  • hfs/hfs+: shrink file system not available when sector size > 512 bytes


TESTS:
Any testing is appreciated.  If you are not sure what to test, you could try one or more of the following suggestions.

1)  Does gparted recognize your disk device with > 512 byte sector size?

2)  Can you create, resize, and delete a partition?

3)  Can you move, and copy a partition?
    You might want to try a small partition so it doesn't take too long.

4)  Do partition operations work with the file systems you normally use?

5)  If you have a disk device that you can afford to wipe clean,
     can you create a new partition table?

Thanks to Francois Dupoux, gparted-0.6.0-beta1 has been included on the System Rescue CD beta version.  You can download this Live CD at the following link:
SysRescCd-Beta-x86

Hopefully this will help make it easier for testing gparted-0.6.0-beta1.  smile

Re: [SOLVED]Need Help Testing "Align to MiB", and sector sizes > 512 bytes

The "Align to MB" option seems to be disabled in 0.6.1 . Please enable it atleast for GPT . If the problem is indeed due to logical partitions, then it need not be disabled for GPT.

How to use MB alignment with GNU Parted (mostly for GPT disks) for use in shell scripts (without manually doing the math)? Any option in Parted 2.3 to do so. The parted -a option does not support "1MB" parameter. I want 1MB alignment regardless of the physical/logical sector size (even for 512 byte sectors). Thank you.

Re: [SOLVED]Need Help Testing "Align to MiB", and sector sizes > 512 bytes

The next release of GParted (0.6.2) will re-enable "Align to MiB".  The fixes for bug #623630 have been committed to the GNOME git source code repository.  If you need this functionality before the next release then please feel free to check out the git source code and build from source.

the version of GParted 0.6.0 was great but had some different experinces with SysRescCd-Beta-x86.
