re: hostname ?

accidentally replied offlist, so I'm trying to forward to the list for

Right, the OpenBSD version at the time (15 years ago) I think was
raidframe and they called it a serial number, it doesn't really matter
as long as all the drives in the stack are the same.  And it's mostly
important if you've got multiple RAIDS and might mix the drives up.

10 years ago I might have whipped out my copy of Norton Disk Editor
but that doesn't deal with LBA48, etc.  dd and a hex editor could
probably do it but unless you know exactly which bytes to change
you're likely to damage something more important.

So RTFM.  One point of a RAID is that you can replace drives when they
fail, so there's a way to put the serial number onto a new drive to
match before you put it in.  Just about any new drive will work as
long as you can make a partition the same size as the rest of the
drives.  5 or 10 years down the road it may be impractical to buy
exactly the same size drive.  So the makers of the RAID
hardware/software will have provided a way to prepare a new
replacement drive.

You want to change it on all the drives at once, that's unusual.  But
there's nothing peculiar to Debian ARM about it.  Try looking on
http://superuser.com or posting a question there.  Or maybe there's a
RAID list or forum within Debian.  Because of the larger userbase with
i386/686 and AMD people you're more likely to find an answer.  Or you
could just live with it the way it is and tape a note onto each drive
so you'll remember when you have to replace one.

I've never used mdadm, I'm on an OpenBSD laptop which sometimes boots
into Debian.  My only running Debian right now is on my phone.  No
mdadm man page even.  15 years on OpenBSD, hmm.
