Still crazy after all these years

[Matthew Carpenter]

Ironically, this email chain hits just as my main lappie goes toes-up (on my work's mbp atm).  Came out of slumber and froze.  On hard rebooting, I see it trying to mount the root filesystem, but all I repeatedly get was some messages about Incrementally Starting RAID devices, and complaining about no group "root" or "disk".  Never to recover.

After playing around a bit, and fearing that my SSD was in the process of failing (but it booted grub without problem), I booted from a usb stick and discovered that my LVM root partition seemed fine.  However, the UUID on the partition is not what is in grub!

WAHT?

No clue what happened.  Judging from the number of packages that have yet to be updated, I don't think this is caused by updates.  I could be wrong.  The grub.cfg file is dated Jan 28th.  It's possible I haven't rebooted since then.  (off topic: does anyone have a favorite tool that writes stats to the log periodically?  I can cron up a call to dump "uptime" or "w" to the log, but I figure someone else has already probably written something that is in the repo)

Anyway, thought I'd throw it out to the group.

Kubuntu 14.10 running LVM on a fairly stock build.  I try not to muck with the internals without using the Kubuntu config stuff (automated updates are too valuable to circumvent, although it looks like I haven't been).  I just ran update-grub and the new config file uses "root=/dev/mapper/kubuntu-root" instead of "root=UUID=<blahblahblah>" that was there before.  wow.  I would assume problem solved, but this is odd.  I wonder if I ran an update while I had a bootable thumbdrive in?  I certainly hope that wouldn't cause problems.  And I can't think of a reason any tool might change the UUID of a LVM partition.

Hope you are all well!  Great to see you all still around.
