/filesystem-health

Check filesystem health and integrity:

1. Check filesystem types and mount status: mount | grep "^/dev"
2. Review filesystem health: df -h and identify issues
3. Check XFS filesystem health: xfs_info / && xfs_repair -n /dev/sda1 2>&1 | head -20
4. Check for filesystem errors in dmesg: dmesg -T | grep -i "error\|failed" | tail -20
5. Review SMART status if available: smartctl -H /dev/sda (or available disks)
6. Check inode usage: df -i
7. Review mount options: cat /etc/fstab
8. Check for read-only filesystems: mount | grep ro,

Provide Daniel with:

• Overall filesystem health status
• Any XFS-specific issues (this server uses XFS)
• SMART health status for disks
• Inode usage (can fill up even with disk space available)
• Mount points and their status
• Any filesystem errors from kernel logs
• Recommendations for maintenance
• Warning flags for anything concerning
