-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi Alasdair, Thanks for your response. But I am not convinced. Here is why... 1. I tried a bit-more and I was able to get Input/Output Error on certain locations - everytime - I read that location. (But I still have an open question that on some locations, though the verify reports failure, I do not get an IO Error on read) 2. I do not understand when you say device is live - do you mean mounted? Because I thought that the whole idea of dm-verity was that once the verity device is set-up, it would return EIO when something gets corrupted in the data or hash partitions when that invalid data is read.

I think it only verifies the data the first time it is read and doesn't check for changes underneath while the device is live.
