#49 RHEL/CentOS support for reading Btrfs Cloud images
Closed: Fixed by ngompa. Opened by chrismurphy.

Closed: Fixed
Reopen Issue

State of affairs summary:

  • Btrfs Cloud images will boot and function as normal even on hosts that do not support btrfs (e.g. RHEL). Resizing is also not impacted, as that's generally handled via cloud-init.

  • A standalone Fedora-built libguestfs container will allow image access regardless of host kernel support. See:
    https://bugzilla.redhat.com/show_bug.cgi?id=1970071
    https://src.fedoraproject.org/container/libguestfs .

  • grub2-mount can provide read-only support via GRUB's btrfs.mod and zstd.mod. See:
    https://bugzilla.redhat.com/show_bug.cgi?id=1970538

    https://git.centos.org/rpms/grub2/pull-request/1
    https://github.com/rhboot/grub2/pull/86.

  • btrfs-fuse confirmed as feasible, design work pending

Detailed version

Should the Cloud landing page, where these images are located, contain a note for RHEL/CentOS users, letting them know they can use these images, and point them to e.g. a quickdoc laying out the above options and How To?

Qu Wenruo is working on a read-only FUSE implementation, which @dcavalca has packaged up for Fedora. When it gets to its first stable release, I imagine we can ship it to RHEL/CentOS in EPEL to neatly solve this problem.

Metadata Update from @ngompa:
- Issue assigned to dcavalca
- Issue set to the milestone: Fedora 36 (was: Fedora 35)

This has now landed in EPEL 8: https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2021-7520d38390
