Re: [CentOS] Looking for a RAID1 box

[Fleur]

Hi All, very interesting thread, I add my 2 cents point-of-view for free to
all of you ...

A lot af satisfaction with HP Proliant MicroServer from the first GEN6 (AMD
NEON) to the 1-year old MicroServer Gen10 X3216 (CentOS6/7/8) so I think
yours is the right choice!

In /boot/efi/ (mounted from the first partition of the first GPT disk) you
only have the grub2 efi binary, not the vmlinuz kernel or initrd image or
the grub.cfg itself ...

To be more precise a grub.cfg file exists there but it's only a static file
which has an entry to find the right one using the uuid fingerprint


*cat \EFI\ubuntu\grub.cfg*search.fs_uuid
d9f44ffb-3cb8-4783-8928-0123e5d8a149 root
set prefix=($root)'/@/boot/grub'
configfile $prefix/grub.cfg

Using an md1 software raid mirror for this FAT32 (ESP) partition is not
safe IF you use it outside of the linux environment (because the mirror
will became corrupted at the first write the other OSes will do on this
partition).

It's better to setup a separated /boot partition (yes, here an md1 linux
software raid mirror is OK) which the grub2 bootloader can manage correctly
(be sure grub2 can access his modules to understand and manage this
LVM/RAID : mdraid09,mdraid1x,lvm.mod [1] [2]

insmod raid
#and load the related `mdraid' module `mdraid09' for RAID arrays
with version 0.9 metadata, and `mdraid1x' for arrays with version 1.x
metadata.
 insmod mdraid09
 set root=(md0p1)
#or the following for an unpartitioned RAID array
 set root=(md0)

IMHO installing ex-novo is the easiest path with setup that puts all the
things correctly, building the right initramfs and putting the correct
entry in grub.cfg for the modules needed to manage raid/lvm...
To be honest I don't know how the anaconda installer manage the /dev/sda1
ESP/FAT32/EFI partitions (I'd like it clones this efi partition to the 2nd
disk, but i think it will leave /dev/sdb1 partition empty)

To understand better how GRUB2 works i've looked here : [3] [4] [5]

Happy hacking

Yes, that's even how RHEL/Fedora set it up currently I believe.  But
like you say, it only works as long as there's no other OS on the system
and the UEFI firmware itself is never used to change anything on the FS.
It's not entirely clear that most UEFI firmwares would handle a drive
failure correctly either (since it's outside the scope of UEFI), so IIRC
there's been some consideration in Fedora of dropping this support.

And... I'm not sure if GRUB2 handles RAID 1 /boot fully correctly, for
things where it writes to the FS (grubenv updates for "savedefault" for
example).  But, there's other issues with GRUB2's FS handling anyway, so
this case is probably far down the list.

I think that having RAID 1 for /boot and/or /boot/efi can be helpful
(and I've set it up, definitely not saying "don't do that"), but has to
be handled with care and possibly (probably?) would need manual
intervention to get booting again after a drive failure or replacement.

Are you sure that's still true? I've done it that way in the past but it
seems at least with EL8 you can put /boot/efi on md raid1 with metadata
format 1.0. That way the EFI firmware will see it as two independent FAT
filesystems. Only thing you have to be sure is that nothing ever writes to
these filesystems when Linux is not running, otherwise your /boot/efi md
raid will become corrupt.

Can someone who has this running confirm that it works?

Re: [CentOS] Looking for a RAID1 box

[Robert Moskowitz]

Well I just ordered a Proliant gen10+ microserver, as the gen10 of for 
1/2 the price was the $0.59 hamburger (we ad it, but you can't order it).


I also ordered 4 Seagate 4T terascale drives (seems nothing smaller around).

So in some 2 weeks I will have it all together and will see what happens 
when I do the install.


:)

Supposedly there is an internal boot usb port in the gen10+

It depends on the version of Grub.  Grub V1 needs /boot to be RAID1 with old

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

Problem comes back to it is ARM.

I have their Odroid HC4 for doing RAID, but could not get any Linux but

Yes Sir,
there is an add-on board for the H3+, 
https://www.hardkernel.com/shop/h2-net-card/ that gives four extra 2.5GBps 
ports.

It's not just you.  I was recently searching on Google and I couldn't find what 
I was looking for.  I kept getting that annoying blue fishing monster.  I then 
went to Duck Duck Go and got what I was after.  On returning to Google and 
using the same exact search phrase that was returning nothing prior, I then got 
the same hits as on Duck Duck Go - go figure!!!

Re: [CentOS] Looking for a RAID1 box

[Robert Moskowitz]

After a lot of hours searching, here is what I am coming to

3.5" 2-bay standard built just does not exist these days.  Pretty much 
everything is at least 4-bay.


the HP Proliant gen8 looks like a good deal, and only use 2 bays. Some 
models have RAID1.


9x9x10 case, not too bad.

The 1U setups end up being more as they expect them to be used for big 
servers.


Or I head over to Microcenter tomorrow (have to go anyway for a few 
items, 8mi away) and see what we can build.  They have a few 2-bay boxes.


One "enticing" aspect of the gen8 is one pair of drives, 1Gb, for the OS 
and another pair for the mail.

All modern Linux kernels include software RAID out-of-the-box.  This means any
system that supports more than one disk that you can install Linux on
(including CentOS) can be set up with Linux software RAID.  If you want
hot-swap, there are various SATA hot-swap units than can be mounted in a ATX
case with front 5" or 3" spaces.  A modern ATX motherboard with a AHA SATA
controller will support Linux, including hot-swap SATA disks, including SATA
connected SSDs.

I have LOTs of ARM boards here and have been working with them for over

Re: [CentOS] Looking for a RAID1 box

[Robert Moskowitz]

It will go into my rack cabinet so I COULD do a 1U format.

I would prefer something sitting on a shelf in the rack (next to my QNAP 
NAS) about the size to handle 2 HD and system board.


Enough memory for Centos and the mail server software.  Perhaps 2Gb is 
enough?  4Gb nice to have (anti-virus could eat up memory at times?)


Oh, has to be Intel not ARM (iRedMail req)

I don't need hot swap.  I just did a drive replace on my QNAP and it 
took ~10min to power down and swap drives.  Took 10hr to mirror to the 
new drive.


I DO want it all in the box.  No external drives.

And I don't want to build my own hardware.  I want to buy it, install 
drives, attach boot ISO, and install away.


Low power like 40W or less good.

This help?

Entry Level Dell Poweredge T150 servers could work, or build your own 
rig with an SLI MegaRAID or HighPoint RocketRAID dedicated controller 
card.


There are configurations like this in a Rackmount configuration, tower 
configurations, or Mini Server configurations, it all depends on what 
kind of space / budget / environment it is going in.

system that supports more than one disk that you can install Linux on 
(including CentOS) can be set up with Linux software RAID.  If you want 
hot-swap, there are various SATA hot-swap units than can be mounted in a ATX 
case with front 5" or 3" spaces.  A modern ATX motherboard with a AHA SATA 
controller will support Linux, including hot-swap SATA disks, including SATA 
connected SSDs.

Re: [CentOS] Looking for a RAID1 box

[Christopher Wensink]

It depends on the structure of the drives.  Do you want a dedicated 
controller card or is an embedded card on the motherboard acceptable?


Entry Level Dell Poweredge T150 servers could work, or build your own 
rig with an SLI MegaRAID or HighPoint RocketRAID dedicated controller card.


There are configurations like this in a Rackmount configuration, tower 
configurations, or Mini Server configurations, it all depends on what 
kind of space / budget / environment it is going in.


Reply back with more details if you want a better answer.

Help?

I am looking for a box I can drop Centos or one of the spinoffs that:

Has RAID1 internal (not an external USB RAID thing)
    Can be software or hardware

small (4TB/drive fine) and low power

I plan to use it ONLY for email server.  perhaps iRedMail

I have spent a lot of time looking and not finding any such piece of 
metal.


All I find are NAS boxes with their own OS.

thanks
