Hello, I run a setup with 2 SAN-boxes attached to a server using the multipath-tools version 0.4.7 and kernel 2.6.17 (the qlogic-drivers do not compile against 2.6.18 ff.). I had no problems setting this up (despite some udev-trouble due to an older dmsetup). But when I try to access volumes > 2tb I get something like [root@backup]/var/log> fsck /dev/san/estor02lun0p1 fsck 1.37 (21-Mar-2005) e2fsck 1.37 (21-Mar-2005) The filesystem size (according to the superblock) is 1202399223 blocks The physical size of the device is 128657399 blocks Either the superblock or the partition table is likely to be corrupt! Without multipath the device is accessible and fsck'ble. I suspect a 32bit-wrap because of [root@backup]~> bc bc 1.06 Copyright 1991-1994, 1997, 1998, 2000 Free Software Foundation, Inc.

Any idea which part of the multipath puzzle is the 32bit bottleneck?
