Hi there,


I saw your message into support.   First and foremost, it sounds like you desperately need to get yourself a UPS if you're having that many power failures.  Having a power failure while data is being written to the system can cause filesystem corruption and data loss.  From reviewing your logs, you do have a few devices showcasing issues.  The best advice I can give you at this point would be to start the array in maintenance mode and attempt to do file system checks / repairs.

All the best,
