Re: ANNOUNCE: mdadm 1.6.0 - A tool for managing Soft RAID under Linux

Thanks David,

I think you and Neil are saying the same thing. I'm going to do some reading

I can see why you said that.

my reading is that --auto *creates the major/minor numbers* by which the
kernel recognises partitions.
It doesn't create the partitions.

I don't have an hdg, but if I did its partitions would be addressed like

so:

david@ash:~$ ll /dev/hdg3
brw-rw----    1 root     disk      34,   3 Apr 15  2001 /dev/hdg3

I'd still need cfdisk et al to set the start/end blocks for the device.

Maybe:

--auto=partition creates the device files for partitions on the array
which may then be manipulated as normal by cfdisk et al

would be a good --help entry?

I did finish, but the example seemed to show that the --auto would build

cfdisk

but it seemed unnecessary at that point

You must finish reading what Neil said!

< Then
<    cfdisk /dev/md/XX
< will allow you to partition the array.

He has more info you somehow skipped!
Re-read the email from Neil.

The simplest way to access this functionality is with

   mdadm --create /dev/md/XX --auto=partition --level= ....

How does in know how big to build the partitions?
How does it know how many partitions?

Can you do it with out building the partitions automatically
and instead it will just build /dev/mdXX and then I can use
fdisk, sdisk, cfdisk... to build my partitions?

Thanks
Jay
