The point of RAID with redundancy is that it will keep going as long as it can, but obviously it will detect errors that put it into a degraded mode, such as a failing disk. I monitor SMART on all the drives and also have mdadm set to email me in case of failure but I'd like to know my drives occasionally "check" themselves too. How would you check a running RAID to make sure all disks are still preforming normally? However looking for these scripts again now I'm finding it hard to find anything which seems similar to what I ran before and I feel I'm out of date and not understanding whatever has changed. Obviously backups are important and I'm taking care of that also, however I know I've previously seen scripts which claim to help against this problem and allow you to check your RAID while its running. However I've heard various stories about data getting corrupted on one drive and you never noticing due to the other drive being used, up until the point when the first drive fails, and you find your second drive is also screwed (and 3rd, 4th, 5th drive). Its currently mdadm RAID-1, going to RAID-5 once I have more drives (and then RAID-6 I'm hoping for). I'm starting to get a collection of computers at home and to support them I have my "server" linux box running a RAID array.
