lvm and raid woes

[Norman Bridges]

Hi

I'm having problems with a combination of software raid 5 and two 
logical volumes defined on top of the md0. Various information about 
both is shown below. The system is Whitebox 4 fully patched.

I've created ext3 filesystems on both logical volumes, and succesfully 
populated these with data.

A problem arises when I reboot the system, when I find that the first 
logical volume "software" is mounted ok, but the second one "images" 
fails at the fsck stage. Consistently it claims that the journal inode 
is corrupt. It is worth noting though that if I comment out the mounts 
from fstab, and mount them by hand once the system is up then no 
corruption occurs. This all looks as if there is a timing condition 
between mdadm and lvm during the rc.sysinit phase, but I can't get to 
the bottom of it. Any help would be much appreciated.

Thanks
