I have now tested with 6-CURRENT compiled from sources dated 2004.08.29.21.00.00 (which includes your patch), and I must unfortunately report that it does not fix the problem. I tested by duplicating a bunch (9GB+) of binary files with known crc checksums on the same filesystem, and I ended up with ~10% corrupt files. Running the exact same test under a kernel compiled without SMP worked without any problems. (Testbed: SMP machine with 4 SATA discs in a gvinum RAID-5 array) I have managed to secure some more testing time on the server today, so I will be trying this with regular vinum later to see if that makes a difference. I'll report back here on the list. /Daniel ErikssonReceived on Mon Aug 30 2004 - 11:52:32 UTC
