This made no sense, sorry.
No system should really run main system volume on LVM thin (or at least
there no great need for it) so the typical failure case would be:
- data volume fills up
- entire system crashes
THAT is the only problem LVM has today.
It's not just that the thin pool is going to be unreliable
But that it also causes a kernel panic in due time. Usually within 10-20
seconds.
