I got this error with yesterday ; yesterday -d /COPYRIGHT diff -c /dump/quenix1/2005/1222/COPYRIGHT /COPYRIGHT diff: /dump/quenix1/2005/1222/COPYRIGHT: Input/output error [status 1] ; with this message on the terminal where i start venti and vnfs: % err 0: read too small: asked for 128 need at least 300 cannot open venti disk b8ab9f305bd8b1b7b5e7c18186e7336a94107e2c: read too small: asked for 128 need at least 300 I don't know what exactly it means.
