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?
