Hi Everyone,
My area had a power outage in the middle of the night that outlasted my UPS battery. As many of you would do, I slept through the outage soundly knowing I am protected by OMV RAID, quality drives and UPS, the nut plug-in, and a backup/restore strategy. I believe my server shut down gracefully when the battery became low, though I'm not sure how to confirm. I was relieved to find no scary fsck 'not clean' or 'fixing this block or the other' warnings upon bootup, but I didn't find any comforting 'booting from graceful shutdown' messages either. How can I confirm a graceful shutdown? Pertinent info and logs follow.
