F15 Feature - online Ex4 defragmentatnion (Re: e4defrag support?)
Hi, 2010/10/6 Eric Sandeen sand...@redhat.com: OK gang, it's in e2fsprogs-1.41.12-6.fc15 you have to invoke it with -test options to make it go ;) Word of warning, it's not had a lot of attention, and the whole design could change in the future, but it's something to play with :) -Eric Would it make sense to propose online ext4 defragmentation as a Fedora 15 feature? Rationale - more people would point their attention to this feature - more people would test it. Contingency Plan: None. Just delete feature from features page :) I'm not sure how it is in other distros, but it's probably not very popular feature. Any suggestions? Kind regards, Michal -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel

At this time, I don't think I'll be able to commit to that work. I'd usually sign up a feature for Fedora when it is reaching completion upstream, rather than using Fedora as a driver for upstream priorities...

I did not mean burdening your in bug reports with the annotation please fix this bug before F15 :) All bug reports should be sent to NEC's e4defrag developers. It seems to me that they are the most appropriate people to fix e4defrag bugs (of course if they still want to maintain this project - it is hard to deduce anything from git log - only five commits after merge - one from author). -Eric Regards, Michal -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel
