But then, a few years ago Apple went and built their own LVM like thing called Core Storage and made it the default. But then they also have high level tools aware of all the parts of the stack so that when you do 'diskutil repairdisk' and point it at a disk, it not only fsck's that file system, but it also checks all the Core Storage metadata found on the PV for consistency, and the EFI system partition on that disk, and even the GPT. The GUI version of the program does the same thing, it knows about the whole stack. But I find it ironic Apple went with an LVM like thing right at the time I was opining Fedora to drop it for Workstation. *shrug* And now Apple has a new filesystem to replace HFS+ and CoreStorage. It's not nearly as sophisticated as ZFS or Btrfs, but it's a kind of pool based file system with reflinks and snapshots similar to Btrfs, with no checksumming or the replication and dedup features. So one of these years...maybe we get a Btrfs kernel developer back at Red Hat or in Fedora to support getting us off LVM. Funny enough, part of the argument for NOT dropping LVM was the impending move to Btrfs and not wanting to make multiple back to back changes. Kinda too late for Fedora 25 now, but it might be interesting to refloat the idea of dropping LVM on Workstation for Fedora 26 if there's no light at the end of the tunnel for a Btrfs transition. -- Chris Murphy -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://lists.fedoraproject.org/admin/lists/users@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
