#198626 — Hrdware question

I am running Debian Stretch on my 64bit Linux platform.

I am planning on installing a 500B SSD as the boot HD and have a 
question about the SATA connectors on the ASUS M5A97 R2.0 MB.

I have what I thought was a simple question, but Google has not been a 
friend to me.  What I found via that route was that the 6 SATA ports are 
the same.  Should the boot drive be plugged into SATA8G_1?

Thanks in advance.

I don't know about your board, but usually you can set the boot
priority order in the BIOS. Probably you can use any of the SATA
ports.

Or _0 if it exists. Check dmesg to see whats the first one found.

I'm assuming that you have looked at the manuals Asus  MB are well 
documented)! :)

Going through the URL (1) without reading the "docs" the SATA internal 
ports are apparently "all the same" but you might want to be careful if 
you plan to use raid.

I appreciate the responses. I have looked a the MB Manual and the BIOS 
in both the easy mode and the advanced mode. (incidentally, the BIOS is 
current)

I have three dives on the platform:

I installed the current Debian Version on the 2TB HD as it was new at 
the time.

Unfortunately, the boot sequence on the EZ Mode screen is only shows the 
WD 500GB drive and the cdrom drive. I can only see the 2TB drive, upon 
which I installed grub, by hitting F8 and selecting the 1TB drive for 
booting.  Now the last time I installed a HD on the system I can't say 
as I paid any attention as to which connector each drive was plugged 
into.  Hence, the question that started this thread.

As I am strictly a user of computers I am very hesitant to mess around 
with the hardware and the BIOS.

let me finish his email by saying that I am most appreciative of the 
patience and consideration of most of the users of this list!

Recommended, but not necessary. After a BIOS reset, any HD or SSD plugged into
that port should be recognized as /dev/sda. Putting your preferred boot device
on it might be the easiest way to have an otherwise unrecognized device become
recognized, but you should be able to have it recognized as primary via advanced
BIOS setup regardless.

This answers my question.

Thanks for the information.

Today grub is using uuid to find out which drive it needs to boot from.
On my hobby server I have 8 drives in raid1 and when the storage (LSI) comes
up some times some drives are initialized before others, but using UUID
instead sda, sdb etc makes it work like a charm.

[Multipart message — attachments visible in raw view] — view raw

I have not gone thru OP's motherboard manual, but on my HP workstation, the
ports are numbered _0 thru _5 and if only one drive is plugged in total
then it will be /dev/sda. However if two or more are plugged in then the _0
is sda.

I will assume that you have one computer, an Internet gateway, and an 
Ethernet cable between them.


Hardware can be easy.  Get an anti-static wrist strap and take your 
time.  Read the users manual for the various components.  STFW and watch 
YouTube videos to learn more.


BIOS can be easy.  Load the defaults and only change those settings 
which you have a compelling reason.  Again, learn as required.


Linux, FOSS services and applications, and their myriad settings and 
interactions are all never-ending learning curves.


Looking at the motherboard users manual:

http://dlcdnet.asus.com/pub/ASUS/mb/SocketAM3+/M5A97_R2.0/E7438_M5A97_R20_Manual_web_hi-res.pdf

Section 1.2.9, item 4, is titled "Serial ATA 6.0 Gb/s connectors (7-pin 
SATA6G 1~6)".  Unfortunately, the motherboard and connector diagram has 
been badly pixelated, but the SATA connectors appear to be labeled 
SATA6G_1 through SATA6G_6 (?).  Please confirm.


I recommend:

1.  Get a small, fast, high-quality SSD to use as the system drive. 
Connect it to motherboard port SATA6G_1.

2.  Connect the optical drive to SATA6G_2.

3.  Do a fresh install of Debian onto the SSD.  Partition manually, 
creating three primary partitions: /boot (1 GB), swap (1 GB), and root 
(10 GB).  Leave the remaining space unused.  This will give you a system 
image that can fit on a 16 GB USB flash drive, a 16 GB SDD, or a 25 GB 
Blu-ray disc.  The first allows you to carry your desktop in your 
pocket, using laptops and PC's as convenient.  The second gives you the 
best performance.  The third is for taking archival images.

4.  Connect the 500 GB HDD to SATA6G_3 and the 2 TB drive to SATA6G_4. 
Mount the HDD partitions and/or directories as desired.  Adjust owner 
and group identifiers as required.

5.  Use the system drive for the operating system, applications, and 
carefully-chosen data.  (I keep my e-mail and CVS working directories in 
my home directory on the system drive.)  Keep the rest of your data on 
the HDD's.

Oh my!
Thank you so very much.  That, in part, is what I am planning on doing. 
Certainly attaching the SSD to SATA6G_1. The rest I will decide as I go 
along,

Mind to explain why should /boot be on a separate partition ?

It used to be the case that various bootloaders would not be
able to boot from a partition larger than a certain size.

If your root partition is encrypted, or uses an exotic
filesystem, a separate /boot may be needed.

A separate /boot may be used as part of a rescue booting system,
so that you can fix a broken /.

If none of those reasons apply, you can safely have a unified /
and /boot.

It used to, in a very distant past. Bootloaders which cannot boot from a 
1 GB partition must have long gone.

I know all this and did not ask why may /boot be on a separate partition 
*in general* but why should /boot be on a separate partition *in the 
specific context of this thread*.

Hello Pascal,

when you have /boot on a seperate partition, you can mount it read-only 
and only when kernel updates arrives, you mount it read-write.

You can do that with other quasi-static parts of the filesystem such as 
/usr too. So what's special with /boot which justifies mounting it 
read-only more than other parts ?

Primarily because I often use dm-crypt on swap and root; boot must be 
unencrypted.

While unencrypted /boot is the most common setup (mine too), you *can*
have encrypted /boot to:

  https://libreboot.org/docs/gnulinux/encrypted_debian.html

Some assembly required :-)

Plain dm-crypt or LUKS ?

Only if using plain dm-crypt. GRUB can handle LUKS encryption on /boot.

Whatever d-i sets up.

I have no doubt that people have figured out many other approaches to 
encryption.  I prefer KISS, so I use what d-i offers.
