[xcat-user] [xcat-users] Deploying Ubuntu server software raid 0

[Oscar Y. <osc...@bs...>]

Dear Xcat-users,

I'm facing some doubts when deploying Ubuntu Server 16.04 with custom 
partitions over software raid0.

I've checked the xcat-docs: 
http://xcat-docs.readthedocs.io/en/stable/guides/admin-guides/manage_clusters/ppc64le/diskful/customize_image/cfg_partition.html 
and created three files:

1 - "partitions-raid0" with this code in it:

raid ::
500 10000 1000000000 ext4
     method{ raid }
     .
2048 512 2048 raid
     method{ raid }
     .
0 2 0 ext4 /
     /dev/sda#/dev/sdb
     .
0 2 0 swap -
     /dev/sda#/dev/sdb
     .
2 - "partitions-disk-raid0", which serves to define the two disks that 
will be used to create the software raid.
/dev/sda /dev/sdb

3 - And finally some extra commands in "partitions-extra-config-raid0"

d-i partman-auto/method string raid
d-i partman-auto/disk string /dev/sda /dev/sdb
d-i debconf/priority string critical

And defined my osimage with the partitionfile attribute like this:

partitionfile=/install/custom/partitions-raid0,d:/install/custom/partitions-disk-raid0,c:/install/custom/partitions-extra-config-raid0

I'm not sure if this setup is correct, because I have been not able to 
past some weird error in partman telling me that it's reading all 
physical volumes, then hangs. But that's another issue, maybe more 
related to debian/ubuntu that this case is.

Thanks in advance for your time and help.

Kind regards,

--
