Grub1 doesn't support booting off LVM, so you'll have to have a separate /boot partition. If grub2 were available in CentOS 6 (and it isn't - rumors are maybe in EL7) then it would be possible to have /boot reside on LVM. Some time ago I set up a system without a separate /boot partition on LVM with grub2 using Debian (I did the same with a Fedora system since). I don't see an issue with having a separate statically sized /boot partition. 100MB for CentOS 5 and 512MB or so for CentOS 6. Besides, what is on /boot that really needs to be backed up? Probably not much of anything that's different from any other system. > > > -- > С уважением, > Халезов Иван > Системный администратор, отдел разработки ПО > НП РТС > > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos > -- ---~~.~~--- Mike // SilverTip257 //
