Also I'am curios is yes, i definetly think that's too small. try 16, 32, and 64. i'm using 32 w/ reiserfs. the only way to really find the optimal size, is of course to try different sizes timing what you typically use the drives for. > there anyway to change the chunksize w/o lossing the raid array and the > contents inside that array ? nope. -- Tom Vier DSA Key ID 0xE6CB97DA
