Hi all,
in order to support the feature in the subject (I need it to install a
server with this particular configuration) I've done a new patch, just
committed in the trunk. With this patch I've introduced a new way to
specify the software RAID volumes inside the autoinstallscript.conf,
instead of using the /etc/raidtab file in the image.
This solution doesn't replace the old one, so for now we have backward
compatibility, even if in the future IMHO it will be nice if we will use
the autoinstallscript.conf for each file system and logical volumes
(LVM, soft-RAID, etc) definition.
The soft-RAID definition is very similar to the LVM syntax. The physical
partitions to assign to a soft-RAID volume is specified in the <part>
tag (like the lvm group) and for the global raid volume options there is
the new special block <raid> ... </raid>. Inside this block you can
specify the same options of the raidtab.
I've attached an autoinstallscript.conf example with both simple
soft-RAID and LVM volumes over soft-RAID volumes definitions. I've
successfully tested it with a SLES9-SP2 distribution.
Let me know if you like this or if you prefer another syntax or another
approach. ASAP, if there are no objection, I'll provide a more detailed
description (updating the autoinstallscript.conf man page for example),
including more details of these new tags.
Here is also a short todo list, but before proceeding the development of
these feature I wait some feedback...
1) spare disks definition (the idea to implement this is to use the
attribute spare_dev, instead of raid_dev);
2) generate the autoinstallscript.conf with soft-raid volumes when
cloning a golden-client (for now the support is only for the server-side)
Regards,
-Andrea
