Hello,

I have one question about EHA.
If I well understand, when a client wants to read or write a file, he first computes a hash of pathname/file and then knows where read or write this file.

What happens if the volume is configured with stripe?
Does the client compute a hash of pathname/file_block?

If the files are striped across n bricks and you totally have m bricks (m should be a multiple of n), for every n bricks a stripe module is the owner say stripe1, stripe2... stripek (k=m/n). EHA algo treats strip1..stripek as bricks. And computes the owner of the bricks which is a set of n bricks. The stripe module is responsible for contacting the actual physical brick.
