Well, on Friday, a directory on the Snap Drive fileshare suddenly had no files in it. Then the directory itself vanished. Peculiar. Then in the Snap Drive’s system log, it started complaining about “broken spans.”
This was not good. But hey, it was a RAID drive, so I wasn’t that worried. Until I realized that the drive had been configured in so-called RAID-0, which is not really RAID at all, it’s just striping. Hence the reference to “spans.” Of course, in my confidence in the safety of RAID, I’d never bothered to back up the drive. Stupid, stupid. Now I’ll be spending upwards of $2-3k to try to recover some of the data, which could have been $50 worth of time and $100 worth of storage.
Lessons: Know the configuration before trusting the hardware. Make backups anyway. Don’t be stupid. sigh
