The filesystem repair is returning errors. The RAID array upon which the filesystem is now reporting a failed drive (having previously reported no failures). I suspect that the power failure may have caused simultaneous drive failures and one of the other drives isn’t being reported as failed yet either. This would explain some of the corruption I saw within the files (and the arrangement of said corruption) in addition to the problems with the filesystem.
