grub-probe on raid10 finds the filesystem, so grub understands raid10. However when I put lvm over raid10, grub isn't able to find the filesystem. LVM on raid1 works. Is it a bug, or am I doing something wrong? I'm using 1.96+20090523-1 but I've tried versions from stable and testing as well. I should think that once grub builds an equivalent of a block device, LVM on raid10 is the same as LVM on raid1. thank mk
