XFS and ZFS Utilities for macOS via Homebrew

On macOS, utilities for working with XFS and ZFS are available through Homebrew, but the selection is limited. For XFS, you can install xfsprogs, and for ZFS - zfs. Both packages support command line and can be integrated into Makefiles for OS development.

XFS Utilities for macOS

XFS (Extended File System) is a high-performance filesystem developed by Silicon Graphics. The following XFS utilities are available on macOS through Homebrew:

XFS Basic Packages

• xfsprogs - basic utilities for XFS management
• xfsdump - utility for backup
• xfsrestore - utility for restore from backup
• attr - utility for working with extended attributes

Important Note: XFS extended attributes allow attaching up to 64 KB of binary data to any inode, including symbolic links, device nodes, and directories. Attributes are divided into two namespaces: root (for superuser only) and user (for all users with write permissions).

Installation via Homebrew

brew install xfsprogs

ZFS Utilities for macOS

ZFS (Zettabyte File System) is a filesystem with volume management developed by Sun Microsystems. The following are available on macOS:

ZFS Basic Packages

• zfs - basic utilities for ZFS management
• zpool - utility for storage pool management
• zfs - utility for filesystem management
• zfs-mount-generator - utility for mounting

Installation via Homebrew

brew install zfs

Integration into Makefile

To integrate XFS and ZFS utilities into Makefiles for OS development, you can use the following approaches:

Makefile Example for XFS

XFS_PROGS = $(shell brew --prefix xfsprogs)/bin
XFS_DUMP = $(XFS_PROGS)/xfsdump
XFS_RESTORE = $(XFS_PROGS)/xfsrestore
XFS_ATTR = $(XFS_PROGS)/attr

# Targets for XFS operations
backup-xfs:
	$(XFS_DUMP) -f backup.xfs /path/to/xfs/fs

restore-xfs:
	$(XFS_RESTORE) -f backup.xfs /path/to/restore

set-attr:
	$(XFS_ATTR) -s user.name value file.txt

Makefile Example for ZFS

ZFS_PROGS = $(shell brew --prefix zfs)/bin
ZFS = $(ZFS_PROGS)/zfs
ZPOOL = $(ZFS_PROGS)/zpool

# Targets for ZFS operations
create-zpool:
	$(ZPOOL) create mypool /dev/disk1

create-zfs-fs:
	$(ZFS) create mypool/filesystem

snapshot-zfs:
	$(ZFS) snapshot mypool/filesystem@backup

send-receive-zfs:
	$(ZFS) send mypool/filesystem@backup | $(ZFS) receive mypool/restore

Recommendations for OS Development

For flexible work with filesystems during OS development, the following is recommended:

Flexible XFS Utilities

• Use xfs_admin to modify filesystem parameters
• Apply xfs_db for interactive viewing and modification of metadata
• Use xfs_repair for restoring corrupted filesystems
• Work with xfs_io for low-level I/O operations

Flexible ZFS Utilities

• Use zfs list -t all to display all objects
• Apply zfs get all pool/fs to get all properties
• Use zfs set property=value pool/fs to modify properties
• Work with zfs diff pool/fs1 pool/fs2 to compare filesystems

Limitations and Alternatives

macOS Limitations

• Native XFS support in macOS is limited
• Requires using FUSE (Filesystem in Userspace) for some operations
• Performance may be lower than on native platforms

Alternative Solutions

• Use virtual machines with Linux for advanced operations
• Consider switching to another macOS distribution with extended filesystem support
• Use Docker containers for isolated work with utilities

Important: For OS development requiring deep integration with filesystems, it’s recommended to use specialized tools and test them in an environment close to the target platform.

Conclusion

• Basic XFS and ZFS utilities are available on macOS through Homebrew
• OS development requires flexible command configuration and Makefile integration
• Main operations include backup, restore, and attribute management
• It’s recommended to test utilities in an isolated environment before using in production
• For more complex operations, specialized tools or platforms may be required

For full OS development, it’s recommended to study the documentation for each utility and create custom automation scripts for frequently performed operations.
