After powering down my home server, and transferring it from one UPS to another,
Centos 7 now boots into emergency mode only. I can't find a method to copy the system log to my desktop
to attach to this post, so I'm listing a few entries from journalctl -xb that seem like they might be relevant:

I also see multiple listings of errors on ATA1, which I believe is the DVD drive. I have not listed them since it's hard to see how they could be realted tp the current problem. In addition to sda I see a listing of sda1, and I don't understand why. My working hypothesis is that the root problem is that the SSD is failing, and that the solution is to do a clean install on a new SSD. Any helpful comments greatly appreciated. |
