Disk Druid and RAID 10 Partitions

[Aero Maxx D]

If I am using a raid 10 setup on 4 Hard Drives, would I make a raid 
partition of 250MB on each of the 4 drives as in total this would be 
500MB, or would I still make a 500MB raid partition, same for swap still 
make a 4992MB partition or halve it and spread it over the 4 drives ?

Below is how Disk Druid sets up the partitions itself when using only 1 
drive.

VolGroup        1144192
     lv_root     51200    /            ext4
     lv_home     229472   /home        ext4
     lv_swap     4992                  swap

sda
     sda1        1                     BIOS Boot
     sda2        500       /boot       ext4
     sda3        285686    VolGroup    physical volume (LVM)

Thanks
Daniel

1 x RAID 1 for /boot over all 4 drives
grub-install /dev/sda-/sdv/sdd to have all bootbale

1 x RAID10 for the OS
1 x RAID10 for data

SWAP can these days be a file
/home is here a folder on /mnt/data with a bind-mount

this setup runs on 2 identical machines once installed and
with dd over ssh cloned since june 2011, originally F15 and
in the meantime updated to F15

Hello Reindl,

Thanks very much for replying to my question, what if I wanted swap to
be a partition tho, would I create a 4GB partition on each of the 4
drives or make it 2GB partition on each of the 4 drives?

What about using LVM with raid 10?

no idea, since i wanted the setup as easy to maintain as possible
in the case of a drive failure i decided only to split boot, system
and data and all other stuff i do not want on the system disk
is on /mnt/data with bind-mounts

my machines have 16 GB RAM, swap is not really a topic there
> What about using LVM with raid 10?

also no idea, that is why i took 2x4 TB disks
enough free space for the next 10 years
of the 1.6 TB used are 500 GB local backups
and the rest contains a bundle of virtual machines
including a backup-vm for nearly all data i maintain

so no, i do not think about expand the array :-)

I'm having a hard time getting it to install the boot loader have
tried installing it on the raid device and also on the master boot
record but both fail.

why do we witch now to top-posting?
this destorys readability

i heard from some troubles with Fedora 16 and RAID
currently no topic for me
> tried installing it on the raid device

this can only be wrong

the bootloader can not act with any RAID device
that is why /boot needs to be RAID1 or a single disk
at boot time it is handeled like a single-disk and
that is also why you need to install the boot-loader
manually on the other drives to have a bootable
machine if your first fails

Am confused as to what you mean, I'm just replying.

I've put /boot on a raid 1 partition.

When installing the boot loader it gives you the option of master boot
record or the raid device so naturally tried both, unsure why it gives
you the option for raid device if this is wrong.

How do you install it manually?

what fedora version are you trying to install?
F16 AFAIk has some troubles with RAID as said

i have no single expierience with F16 exepct that a RAID1/RAID10 setup
in a virtual machine was upgraded without problems but it is still
using GRUB and not GRUB2
> How do you install it manually?

in F15 "grub-install /dev/sdb; grub-install /dev/sdc; grub-install /dev/sdd"
but until now i saw no information what fedora version you try to install
this usually belongs in the initial-post because if i had guessed
from the very beginning you are using F16 i had not replied at all

Ok thanks for that, am now confused as to where supposed to put my reply
doesn't seem to make sense to put it at the bottom now.

what fedora version are you trying to install?
F16 AFAIk has some troubles with RAID as said

Sorry I had thought I had put it in the subject or the body of my original
mail.

I'm using fedora 16. So do you suggest I try fedora 15, will fedora 16 be
fixed in the ISO? Or some hot fix patch later? If the latter I presume
there would be no way to do raid setup at install?

in F15 "grub-install /dev/sdb; grub-install /dev/sdc; grub-install /dev/sdd"
but until now i saw no information what fedora version you try to install
this usually belongs in the initial-post because if i had guessed
from the very beginning you are using F16 i had not replied at all

Thanks for that, but from what you said about not replying at all, that's
not very helpful as how are they supposed to know there is a problem with
fedora 16 and raid, I've googled this extensively and not found any mention
of this!

Thanks very much for replying to my question, what if I wanted swap to

no idea, since i wanted the setup as easy to maintain as possible

in the case of a drive failure i decided only to split boot, system

and data and all other stuff i do not want on the system disk

is on /mnt/data with bind-mounts

my machines have 16 GB RAM, swap is not really a topic there

What about using LVM with raid 10?

also no idea, that is why i took 2x4 TB disks

enough free space for the next 10 years

of the 1.6 TB used are 500 GB local backups

and the rest contains a bundle of virtual machines

including a backup-vm for nearly all data i maintain

so no, i do not think about expand the array :-)

usually bugs get fixed of the lifetime of a version

BTW:

normally you have the option to include updates-repo while doing
a fresh install (hopefully this was not messed in F16) and so you
can avoid the most release-bugs by get the latest versions including
kernel

but this helps only if anaconda is not broken in the setup you need
i will know this ina short time - in the next two weeks a new
(small) server will be delivered to me which should be F16
with 3XRAID1 (boot, system, data) and i would love that it
works without spending some nights :-)

I see I will give that a try I suppose I will be clicking on the
additional repos button to add this?

I got myself a small mini itx board does what I need it to do well,
just need to get it up and running now, then can put my current one
into retirement :-) as it struggles with anything above fedora 8 mouse
is really jerky like stops and starts when moving it. It's a via c3
processor tho I think that's part of the problem.

What you are supposed to do for the most part is answer questions inline
and just after the questions they answer. Also you should delete parts
of the message you are quoting that aren't needed to continue the
conversation.

It makes even less sense to keep top-posting.

Also, you might want to check your settings for quoted material. The
current message is virtually incomprehensible not only only because of
the top-posting but because you don't distinguish between quoted
material and your own comments (such as using the "> " line prefix as
above).

It's in your own interest to make these conversations readable.

Well I replied on an iPhone as I am now with this reply, it looks
quoted on my phone so had no idea it wasn't to anyone else as no one
else has mention it before.

The problem is that you're "just replying" using the default Gmail
top-posting style. Many lists, especially those of a technical nature
such as this one, frown on top-posting. In fact it's even stated
explicitly in the list guidelines (see the URL at the end of every
message on the list).

I also use Gmail, though for list traffic I'm almost always accessing it
via Evolution. However even when using the Web interface I'm careful to
avoid top-posting when replying to list messages.
