From Bugzilla Helper: User-Agent: Mozilla/5.0 (compatible; Konqueror/3.5) KHTML/3.5.7 (like Gecko) Description of problem: This result is obtained for: parted-1.8.6-10.fc8.x86_64.rpm and parted-1.8.6-12.fc9.x86_64.rpm. Installing parted-1.6.22-3.FC4.x86_64.rpm, however, yields a working version. Version-Release number of selected component (if applicable): parted-1.8.6-10.fc8.x86_64.rpm How reproducible: Always Steps to Reproduce: 1. Install Fedora 8 2. Attach a 4TB (RAID) volume 3. Run: parted, select /dev/sdx, and print Actual Results: "Error: Unable to open /dev/sdx - unrecognised disk label." Expected Results: Disk geometry for /dev/sdx: 0.000-4767742.500 megabytes Disk label type: gpt Minor Start End Filesystem Name Flags 1 1.000 3375000.000 ext3 2 3375001.000 4767740.000 ext3 Additional info: Note that even with the parted-1.6.22-3.FC4.x86_64.rpm, however, if instead of using the "select" subcommand, I start parted as "parted /dev/sdx", the following appears: "You found a bug in GNU Parted. Please email a bug report to bug-parted@gnu.org containing the version (1.6.22), and the following message: The sector size on /dev/sdx is 2048 bytes. Parted is known not to work properly with drives with sector sizes other than 512 bytes Ignore/Cancel?" If I choose "Ignore", then, parted works as expected. Note also that the volume sector size is, indeed, 2048 bytes. Although I am accepting the "Severity = Medium" for this, given that using parted to create GPT partitions is the only reasonable method for managing greater than 2TB partitions, I think that this bug (and the inability to handle sector sizes other than 512 bytes) should be fixed soon.
We are working on this upstream. The latest version appear in rawhide, so if you can try those out, it would help us.
It might be a sector size issue, the current upstream is working hard to solve this matter. Some further testing needs to be done, but I expect a new release of parted to be around the corner with this fix.
This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '8'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 8's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 8 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
parted-1.8.8 is now available and hopefully fixes this bug. It would be great if anyone could confirm this.
At least for the sector size issue, parted upstream does not solve the problem. parted still is unable to work with sector sizes different from 512.
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle. Changing version to '11'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
The sector size issue is fixed upstream in the 2.0 release. We will rebase to 2.1, which will be out soon sometime in the future, closing.
