More than likely your system is doing some weekly admin tasks like log
rotation, stats processing or running the slocate cron job.
Note the time it occurs, and check the running processes at the time - you can
use top in 'Batch mode' and send its' output to a file. This can be left
running, or just run it as an at job prior to the time the CPU kicks off and
let it track the culprit. Then when you get out of bed you can track it down -
beats staying awake!
I doubt it's LVS related.
