When I woke up this morning, one of my boxen had spewed out a ton of
errors from one of my SSDs (the root drive), remounted read-only, and
went into a kernel panic.
After rebooting everything seems fine, though. I've ran a SMART long
test, but as I found out the SMART error log is not supported on this
drive. Neither do I have the log of what happened, since / was
remounted ro.
I've included the output of "smartctl --all /dev/sdc", but I can't see
anything that stands out.
Yesterday, I had another kernel panic (that seemed related to systemd),
so I suspect the (manually built) kernel to be at fault here. The RAM
in this machine is all brand new, and I ran memtest less than two weeks
ago, so that should be fine.
Can anyone look at this log and tell me if there is anything to worry
about? Which of the attributes should I look at, so that I know in the
future?
(And I did a full backup as recently as yesterday that was tested OK
at the time, so data loss is not a concern. Everything important is on
other drives anyway.)
