  • Is my open-source project up to date with MIT license compliance and attribution?

    My projects and many projects include a THIRD-PARTY-LICENSES.html file when I distribute binaries. See:

    The only real advantage I can think of with nested ZFS is that the files in the KVM would obviously be individual inodes in the nested ZFS filesystem and datasets, in addition to the one inode per virtual volume on the hypervisor (or zvol). This would allow for granular file management on the kvm and the use of tools like which is like a command line time machine for ZFS.
  • ZFS silent corruption bug found: replaces chunks inside copied files by zeroes

    > It's worth noting that copy_file_range is used by a lot of things.

    Yes, but the trigger feature, block cloning, only landed in the latest 2.2 release. If you immediately hopped on 2.2, and used a system with lots copy_file_range and FICLONE use, yes, you may have a problem (like, as you note, on Gentoo, where this problem surfaced).

    Most people were just hopping on the bandwagon. My distro ships 2.1.5, so I have a 6 month wait until this feature lands, so I was just building copy_file_range support into my ZFS apps, right before news of this bug hit.[0]

    > There are other things required to trigger the bug that are a lot less common though.

    Exactly. My guess is the incidence of this will exceedingly rare for the common user/small NAS user/etc. I've run a corruption detector[0], and what I've found mostly indicates false positives. Some are build artifact fingerprints, which I don't care about, and which were deleted with the next build. The ones with an extant file on another system, I confirmed were a diff match with the origin using `rsync -rincv` and whats on snapshots with `httm --map-aliases`. So far no positive matches.


  • Are you running Linux with a filesystem capable of block cloning/FICLONE (ZFS >= 2.2, XFS, BTRFS)?

  • Workflow: Rolling forward with ZFS and `httm`
    1 project | /r/sysadmin | 19 Jun 2023
    httm prints the size, date and corresponding locations of available unique versions (deduplicated by modify time and size) of files residing on snapshots, but can also be used interactively to select and restore files, even snapshot mounts by file! httm might change the way you use snapshots (because ZFS/BTRFS/NILFS2 aren't designed for finding for unique file versions) or the Time Machine concept (because httm is very fast!).
  • Really no easy GUI Btrfs snapshots for Fedora 38?
    2 projects | /r/btrfs | 6 Jun 2023
    All btrfs snapshot tools can have different layouts. It's mostly a nightmare for any one tool to support. Although its not the tool you're looking for, FYI AFAIK httm supports all/most btrfs layouts, but it took more work than necessary to get there.
