Hi, I haven't tested FC3test as yet and wanted to ask if grub in FC3 would do the right thing when installing on a software raid-1 boot array (ie, that it would write to the MBR on both disks) so if there was a disk failure, the machine would still come up. Currently in FC1/FC2, if you install on software raid-1 array and then remove the first disk, the system won't boot up since there is no boot information on the MBR of the 2nd disk. lilo would do the right thing but since that's being deprecated. I don't know if Grub is capable of this task An engineer from Dell has provided a document which gives a workaround for this http://lists.us.dell.com/pipermail/linux-poweredge/2003-July/014331.html Regards, Yusuf
