It doesn't enable all the on-disk format stuff; uninit_bg and flex_bg can also be tune2fs'd on, although honestly I think this could use more testing for corner cases. > (and then remounting as ext4dev) should work. > > Also is there (going to be) any sort of online defragmentation support > to make a converted ext4 use extends for all files? There is talk of that, but defrag support is not yet available. The patches are in the pending queue but not getting a lot of attention ATM. There have been other options discussed, such as transparently re-writing at least small files in extents format (though this wouldn't improve existing allocation). -Eric -- fedora-test-list mailing list fedora-test-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-test-list
