After changing the mount option to use tcp instead of udp I have now read several gigabytes without a single error.=20 Is there some fundamental difference in how nfs over upd and tcp is handled regarding the packet contents like tcp using the tcp checksum and udp not using the udp checksum or something like that? Are there any counters for checksum errors in udp and tcp that can be read ?? I faild to spot anything in /proc. --=-zwaszzLro9Rkk4trfNfF Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQBClNxnmDGOmJIy9x8RAs4fAJ4+r7WkNZJeQYv2OUtYfokyD5YK7gCeJMN9 ldE7YhM0A32atEyjK1X2L7o= =GXjC -----END PGP SIGNATURE----- --=-zwaszzLro9Rkk4trfNfF-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
