confirmed ... :-)

Another question on this. Especially the module itself.

We will upgrade our backup-server to an external SCSI-HDD-Tower with 8*148=
=20
GiB SCSI-HDDs plus one TapeDevice.

Our Backup-Server itself will have no HDDs anymore in it afterwards.
The basic installation will be ...

/dev/sda1	/boot	->	50 MiB		ext3
/dev/sda2	/swap	->	1 GiB
/dev/sda3	/	->	5 GiB		ext3

/dev/sda4	none	->	141,95 GiB	Linux RAID
/dev/sdb1	none	->	148 Gib 	Linux RAID
/dev/sdc1	none	->	148 Gib 	Linux RAID
/dev/sdd1	none	->	148 Gib 	Linux RAID
/dev/sde1	none	->	148 Gib 	Linux RAID
/dev/sdf1	none	->	148 Gib 	Linux RAID
/dev/sdg1	none	->	148 Gib 	Linux RAID
/dev/sdh1	none	->	148 Gib 	Linux RAID


After that is the module ready to do the following (or similar):

"There are partitions reserved to be part of a Linux RAID-System. Currently=
=20
there is no Linux-RAID on your system. Please indicate, which type of RAID=
=20
you want."

	<dropdownbox to select from stripeset to raid x>

(next steps would be for my scenario)

"You have requested to install a RAID 5 system. Should all reserved partion=
s=20
go into that RAID-System?"

	[ ] Yes

(Now Webmin should come up with a reasonable solution, maybe saying)

"If you click on this button the basic RAID 5 system will be configured as=
=20
follows ..."

(maybe)

/dev/sda4		Parity Partition	141,95 GiB
/dev/sdb1 to /dev/sdh1	Data Storage		aprox. 1036 TiB

(what I mean is, that there should be a check if a requested type of RAID i=
s=20
possible with the found HDDs or not, and to show up a possible solution to=
=20
take)

"The basic RAID 5 system has been setup properly. Now you need to choose=20
which filesystem this RAID should have."

	<dropdownbox with possible filesystems>

(what I mean is, that the module should automagically find out which kind o=
f=20
filesystems would be useful according to the filesystem size. maybe it can=
=20
give out a warning: "If you use ext2 or ext3 it will take longer to format=
=20
the filesystem the more huge the RAID system is.")

"The RAID 5 system has been formatted with $1 properly. Now you will be=20
redirected to the Mount-Module in order to mount your RAID 5 system. Its=20
device name will be /dev/md0. Please indicate the mountpoint in the textbox=
=20
and then click on $2".

Well so far for the whitepaper ;-)
