It depends on the version of Grub. Grub V1 needs /boot to be RAID1 with old metadata (metadata at the *end* of the partition, so Grub just sees a plain ext2/3/4 file system to find vmlinuz and initrd). Note: /boot/efi or the grub fs that Grub2 seems to want cannot be RAID, but you should duplicate the partitions across all of the physical disks in the raid set and arange some other way of "mirroring" them (eg rsync or some such -- does not need to be continious, since these file systems don't change continuiously). I believe Grub V2 understands raid and LVM, so having a separate /boot raid set might not be needed. Things like /boot/efi and grub's on fs still need to exist outside of the raid set and will need "manual" mirroring. > > Simon > > > > > Also HPE is ClearOS. I ran ClearOS6 for years before going with QNAP > > turnkey. Perhaps current ClearOS is better, but it does not handle > > multi-domain email as I need. Or it did not. So I am going to install > > my own CentOS variant and iRedMail... > > > > thanks > > > > > > On 1/5/23 13:08, Jon LaBadie wrote: > >> On Thu, Jan 05, 2023 at 08:18:08AM -0500, Robert Moskowitz wrote: > >>> Proliant gen8 does NOT have UEFI. > >>> > >>> So I think this means I better move up to the gen10... > >>> > >> > >> I'm pleased with my Gen 10+ (Plus). Pricer than I thought > >> you want. > >> > >> I like the "no power supply", just an external brick. > >> Quiet. I put in a PCI card to use 2 NVMe sticks, one for > >> system and one for /home. You can also boot from an internal > >> usb port like a thumb drive permanently installed. > >> > >> Carriers for 2.5inch SSD drives work fine so with few fans, > >> no drive motors, could be quite low power. > >> > >> Mine acts as email server, local caching DNS server (dnsmasq) > >> and Amanda backup server. > >> > >> Jon > >> > > > > > > _______________________________________________ > > CentOS mailing list > > CentOS at centos.org > > https://lists.centos.org/mailman/listinfo/centos > > > > > _______________________________________________ > CentOS mailing list > CentOS at centos.org > https://lists.centos.org/mailman/listinfo/centos > > -- Robert Heller -- Cell: 413-658-7953 GV: 978-633-5364 Deepwoods Software -- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services heller at deepsoft.com -- Webhosting Services
