Don't know where you heard that little tidbit. I can tell you that LVM across multiple disks is terrible. When you have a disk die suddenly, all LVs which have PVs on that disk are unrecoverable, UNLESS you are using a redundant raid partition. When using redundant raid, and you loose one disk, you can run in degraded mode until you replaced that failed disk, then you can rebuild the missing portion from the redundant part. Redundant raid is all raids EXCEPT raid-0 which is just striping of the data across multiple disks. All other forms of raid (1, 3, 5, 6, 10) are able to survive a single disk failure and can rebuild when the failed disk is replaced. raid 6 can even survive 2 disk failures!). > Another concern I have is in regard to separate /boot partition which I > was not using on Linux for quite some time, but see that Fedora’s > automatic layout does create it? Probably a more historical artifact these days, but it could come into play if you are using a filesystem that grub2 cannot boot from. > Sincerely, > Gour > -- Kevin J.
