It's happened again. One of my RAID0 arrays just stopped working. The mount command shows it as mounted, but neither the command line nor any GUI file managers can see any files, and if I try to open a file that I know is there I get "Error reading file: Input / output error." Attempts to umount it fail because mount thinks it is busy, and "mount -a" executes without error, but does nothing.
From previous experience the solution is to reboot, which restarts the array and all is well again. I've never lost any data, and if I did I have a full mirror on a Synology, but it's a major PITA to have to reboot. I've searched documentation on mdadm and I can't figure out if there is a way to just restart the array. Suggestions?
