/raid-status

Check multi-disk array and RAID status:

1. Check for software RAID: cat /proc/mdstat
2. If using mdadm, get detailed status: sudo mdadm --detail /dev/md*
3. Check individual disk health: sudo smartctl -a /dev/sd[a-z]
4. Review disk errors: dmesg | grep -i "sd[a-z].*error"
5. Check filesystem on array: df -h | grep -E "(md|mapper)"
6. Review LVM if used: sudo lvdisplay && sudo vgdisplay && sudo pvdisplay
7. Check disk I/O stats: iostat -x 1 3
8. Review array rebuild status if active: cat /proc/mdstat | grep -i resync
9. Check array configuration: lsblk -o NAME,SIZE,TYPE,MOUNTPOINT,FSTYPE

Provide Daniel with:

• RAID array status (healthy, degraded, failed)
• Individual disk status and health
• Array rebuild progress if applicable
• SMART data for all disks in array
• Any disk errors or warnings
• Array configuration (RAID level, devices)
• Performance metrics
• LVM status if applicable
• Recommendations for array maintenance
• Critical warnings if array is degraded or disks are failing
• Suggestions for disk replacement if needed
