dm thin provision, pool full

[Marcus Sorensen <marcus@xxxxxxxxxxxxxxxxx>]

You guys probably already know about this, but I was playing with kernel 
3.2.0 and the device mapper thin provisioned snapshots, and it doesn't 
seem like there is any sort of error implemented when the pool is full. 
I was running some write tests, and one of them just seemed to go into 
eternal D state. Checking iostat showed disks were idle. Running a 
'dmsetup status' returned the following:

thin: 0 41943040 thin 39832576 41943039
pool: 0 41943040 thin-pool 0 622/243968 81920/81920 -


that 81920/81920 is reporting data blocks in use/total blocks, correct?
