I know how RAID work and prevent data lost from disks failures. I want to know is possible way/how easy to recover data from unfunctioned remaining RAID disks due to RAID controller failure or whole system failure. Can I even simply attach one of the RAID 1 disk to the desktop system and read as simple as USB disk? I know getting data from the other RAID types won’t be that simple but is there a way without building the whole RAID system again. Thanks.
Btw: With the regular Linux software mdraid, you can also swap drives without powering down. That all works fine while running. Unless your motherbard SATA controller craps out. But the mdraid itself will handle it just fine.
