I'm thinking about putting all the computers on the network disk
array, including the SOC's: beaglebone blacks, arduino mega256, and
the RPi2. I would not mind doing the compiles (and maybe even the
booting!) on the hard drives instead of the limited-life SD cards
and 'flash' that are on the SOC's. Any of you guys done that?
Everything in the house is 1Gb Ethernet. If only I could get that
to the outside world <heavy sigh.> <span

Already have the BBB's booting of the SD card, which you have to do
with the rev B's and their 2 Gb size..<br>

There was an itsy-bitsy blurb about it on Debian's site but there
were no details given and, doing Yet Another Fresh Install
(copyright), I could not find it in any of the auto OR manual disk
setups. <sigh> This was less than a month ago.<br>

Software Linux raid is fine with the
striping but it sucks at mirroring. The
second (mirror) drive is NOT identical in
any shape form or fashion. Even the
partitions are different. And it is not
bootable!!! In mirroring, I want immediate
fail-over, or at most, one shutdown,
remove/replace drive, then back up right
where I was.<br>

<div>I agree. I had to go through hell with a
Debian mdadm system to install the boot loader
on both drives. I know this is a problem with a
few software raid solutions.<br>
<br>
<br>
</div>
<div>Anyone know if this has been fixed in any OS
+ Filesystem/Software Raid? One of the things
that killed me was if the bootloader was
corrupted on one disk, or the disk was partially
corrupted or something, in a software raid
scenario, the bios has to know to move to the
next disk, but when does that ever happen?<br>
<br>
</div>
<div>This was a big failing with software raid. I
am sure it could be hacked around by placing the
bootloader somewhere else...or something.<br>

Again, this isn't a problem with the software RAID, but just
how Linux works. mdadm doesn't know anything about the MBR
since it's not in a partition. Instead you configure the
bootloader to install itself on the MBR of both drives. IIRC
some installers (Debian maybe?) offered to do this for you.</div>
