Server Technical Specification Working Session http://meetbot.fedoraproject.org/fedora-meeting-1/2014-02-27/fedora-meeting-1.2014-02-27-15.00.log.html > 16:06:36 <sgallagh> simo: To answer your question about overcommit: that is *possible*, but we can be smarter about it in the default partitioning Anaconda currently disallows overcommitting. > 15:48:19 <mitr> (Again, having a per-directory instead of per-user quotas would be rather beneficial here) A related item that came up is quotas. XFS supports project quotas. So that's possible in the case where you're on the fence if something should have a separate LV. Project quotas were just proposed as an ext4 feature last month. My two small concerns about LVM thinp by default: 1. XFS is highly parallel + the parallel writes is a trigger for the current thinp fragmentation issue. So it's a "good" combination to reveal this problem. 2. There is an outstanding bug between XFS and LVMthinp that I think the LVM folks might need to be pinged on. The wrong number of XFS AG's is being assigned to virtual size LVs and this will reduce performance. https://bugzilla.redhat.com/show_bug.cgi?id=1003227 Chris Murphy -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
