patch for [xfs, grub-probe -t fs] and a question about lvm

[Adrian Migraso]

hi... can we add this patch... at least the first patch @ lines 249, i was trying to grub-probe the xfs filesystem under the lvm, and got some error...

 

Also,... i have been trying to use the lvm.mod with the grub, the problem is, my logical volumes are not detected by 'ls' command during grub resucue>

 

is lvm.mod ok?

 

can i have a peek of how grub2 works? I mean its flow... thanks guys...
