I had a hardware raid array, which in the middle of resilvering (with an XFS filesystem), suffered a power loss. It turned out that the initial drive failure was symptomatic of the impending power supply failure, and after replacement of the PSU, was unable to resume resilvering due to a corruption of filesystem metadata...

I carried the drives around in hopes of recovering the codebase for a virtualized+distributed SSI OS (Kerrighed-module-based), which had been in the works for about a year at that point.

Due to changes between 2.4/2.6 and 3.x kernel; the rise of user-level distributed computing in C/RIU, kubernetes+docker, I never really recovered the work: there were partial backups of some of the features scattered across three contributors' systems, but no coherent backup of the unifying components; and well "life" with one of the key contributors becoming 'Justice Impacted' stalled any real progress.

I use this as a personal motivation for RAID!=Backup.
