Created attachment 991846 [details] invalid seek bug Description of problem: Trying to move and shrink partition on USB flash. Got "Libparted bug found!" window with the error "Invalid argument during seek for read" (see screenshot). So, what to do now? Retry/Cancel/Ignore? I also noticed the the flash drive was mounted when the error occurred. But I am pretty sure I unmounted it before operation. Version-Release number of selected component (if applicable): Name : gparted Arch : x86_64 Version : 0.20.0 Release : 1.fc21 How reproducible: Don't know. Additional info: Maybe this https://bugzilla.gnome.org/show_bug.cgi?id=742920 is the upstream bug.
See backtrace generated after hitting Cancel button few times (other options didn't work) https://bugzilla.redhat.com/show_bug.cgi?id=1192769
The reporter is correct that "Invalid argument during seek for read" is fixed by upstream bug https://bugzilla.gnome.org/show_bug.cgi?id=742920. This is included in GParted 0.21.0 and later. I see this bug was raised against Fedora 21 which only has GParted 0.20.0, https://apps.fedoraproject.org/packages/gparted. Will need to update to a later version of GParted to fix. (I see btrfs-progs in Fedora 21 was recently updated to the latest upstream release in Fedora 21 https://apps.fedoraproject.org/packages/btrfs-progs so I therefore see no reason why GParted can't too). Thanks, Mike Fleetwood (GParted Developer)
This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 EOL if it remains open with a Fedora 'version' of '21'. 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. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 21 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, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. 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.
Fedora 21 changed to end-of-life (EOL) status on 2015-12-01. Fedora 21 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
