/xfs-check

Check XFS filesystem health and performance:

1. Identify XFS filesystems: df -T | grep xfs
2. Check filesystem usage: df -h | grep xfs
3. Check XFS-specific info: xfs_info / (or relevant mount point)
4. Review XFS statistics: xfs_db -r -c "sb 0" -c "print" <device> (read-only)
5. Check for fragmentation: xfs_db -r -c "freesp -s" <device>
6. Review filesystem errors: dmesg | grep -i xfs
7. Check filesystem mount options: mount | grep xfs
8. Review I/O statistics: iostat -x 1 3 | grep -A1 <device>
9. Check SMART status of underlying disks: sudo smartctl -a <device>

Provide Daniel with:

• XFS filesystem usage and available space
• Filesystem configuration (block size, features)
• Fragmentation status
• Any filesystem errors or warnings
• Mount options in use
• I/O performance metrics
• Underlying disk health (SMART data)
• Recommendations for XFS optimization
• Warning if space is running low (<20% free)
• Suggestions for maintenance (defragmentation, etc.)
