Explanation
RAID 1 is disk mirroring - two drives hold identical copies of data. When one drive fails, the array operates in a degraded state (still functional but with no redundancy), which is why the server is slow. Replacing the failed drive and issuing a RAID rebuild (repair) causes the controller to mirror all data from the healthy drive to the new drive, restoring both full performance and redundancy. Dismantling the array or continuing without repair eliminates redundancy entirely, leaving data at risk.
