Hi, My name is Gergo Csibra, and I live in Hungary. I'm new to GlusterFS, but not new to Clustering/HPC and programming, I'm in GUG project (http://sourceforge.net/projects/gug) So, I want to make an ECC translator, with this we can make a raid like bricks. I think this very close to encryprion translators, because this does the same thing: reads data from client manipulate this data writes to subvolume an reverse: reads from subvolume manipulate (really only checks, and maybe repair) readed data sends to client. I've looked the rot-13 translator, and after 2 days of missconfiguration I can test it. My questions: The encryption translator reads and writes same amount of data, but I must write more data to device (the original plus the ECC info), and send less to the client (readed minus the ECC). The other thing, if I make for example 4 ECC bytes to every 16 user bytes, maybe I need to read data from before and after the original buffer. What functions must I use, to do this thing? Is there some development documentation? ps. sorry for my english :) -- Best regards, Csibra Gergo mailto:gergo@xxxxxxxxx
