[nflug] quick partition table mirroring

[Robert Meyer]

'dd'? :-)

Actually, you can probably use something like sfdisk to do it.
sfdisk -d /dev/hda > hda.out
sfdisk /dev/hdb <  hda.out

or, more succinctly:
sfdisk -d /dev/hda | sfdisk /dev/hdb

How's that?

Cheers!

Bob

Subject: [nflug] quick partition table mirroring

I'm not sure the subject of this message accurately describes what I'm 
looking but it's kind of close.

I have a Linux server with mirrored drives and one of the drives died. 
I've replaced the dead drive with an identical disk and want to recreate 
the partition layout and rebuild the mirrors, simple tasks. Because the 
disks are identical I'd rather not have to manually create all the 
partitions, I want to suck that info from disk1 and apply it to disk2.

On Solaris I'd use prtvtoc from grab the disks partitions and fmthard to 
apply it to the new drive but haven't been able to locate equivalents on 
  Linux yet. Is anyone aware of how this can be done on Linux?
