Hi maybe there is a feature like this already but then I have to discover that one yet.
We have a bunch of compute nodes in our server farm and some of these
only have a single HDD inside and some of an extra SSD besides the HDD.
Currently I'm using a small script which will determine to which class
this machine belongs to. It works but I think it would be much more
"natural" if setup-storage had the extra disk_config option "optional".
Usually I use a partition hook to order the devices I have, e.g.
$disklist is set-up so that the first entry will always be the HDD and
the second one will be the SSD (if present).
With the optional option I could then simly write:
disk_config disk1 disklabel:msdos fstabkey:uuid
primary / 25000 xfs rw
primary /var 25000 xfs rw
primary swap 8192 swap sw
primary /srv 1- xfs rw
disk_config disk2 disklabel:gpt fstabkey:uuid optional:yes
primary /ssd 1- xfs rw
and be done with it.
Does this sound reasonable or did I already miss something like this?
Cheers
Carsten
