I applied the 1.0.1-rc2 patch to a clean 2.4.9 kernel tree and was able to create a logical volume on top of s/w RAID 1 without any trouble. However, a bonnie++ run on an ext2 (or ext3) filesystem on the logical volume caused the system to lock up, with kswapd going uninterruptible. I suspect a VM (rather than LVM) problem, as a similar lock-up occurred on another system with 2.4.8 kernel and no LVM. We've reverted to kernel 2.4.7 on both systems and had no problems since. -- Ray Miller Unix Systems Programmer Oxford University Computing Services
