Inter-platform coordination
Ideas for projects that would help coordinate changes between platforms:
- Mechanism for pull changes from one place to another
- Make it easier to build, test, code review, and integrate ZFS changes into illumos
- Cross-Platform Test Suite
- One sourcebase rather than porting STF to every platform?
- Userland ZFS
- we already have ztest / libzpool
- want to expand this to also be able to test more of zfs in userland
- want to be able to run /sbin/zfs, /sbin/zpool against userland implementation
- want to be able to run most of testrunner (and/or STF) test suite against userland implementation
- ZFS (ZPL) Version Feature Flags
- Import ZFSOnLinux sa=xattr into Illumos
- /dev/zfs ioctl interface versioning
- Ensure that future additions/changes to the interface maintain maximum compatibility with userland tools
- Enable FreeBSD Linux jails / Illumos lx brandz to use ZFSOnLinux utilities
General features
- device removal
- based on indirect vdevs, rather than bprewrite
- resumable send/receive
- work in progress at Delphix
- Storage of small files in dnode
- work in progress at Delphix
- Reflink[1] support
- Unified ashift handling [2]
- Collapsible ZAP objects (e.g. fatzip -> microzap downgrades)
- Raidz Hybrid Allocator (preferably compatible with pool version 29 for Solaris 10u11 compatibility)
- Replace larger ZIO caches with explicit pages.
- Subproject: Document useful kernel interfaces for page manipulation on various platforms
- Improved SPA namespace collision management
- Mostly needed by virtual machine hosts
- work in progress in Gentoo
- Temporary pool names in zpool import [3]
- Temporary pool names in zpool create
