[one-users] using real disk partitions for storage?

2010-08-11 Thread Dan Yocum

Hi,

I've got a special use case where we'd like to use an entire disk 
partition, i.e., /dev/sdc, for storage space.  Is there a way to create 
an appropriate template with contextualization to tell Opennebula to NOT 
create a file and format it, but format a disk partition?


Thanks,
Dan

Hi Dan,

You can look inside the tm_mkimage.sh and modify it accordingly to your
needs. For example, you could comment out the line (for nfs driver):

 41 exec_and_log "mkfs -t $FSTYPE -F $DST_PATH"

regards,
Jaime

Hi Jaime,

Thanks for the tip.

I realized late yesterday that allocating and formatting a disk 
partition requires root permissions, which the oneadmin user doesn't 
possess.  It might be worthwhile to re-think the level of permissions 
and the write access available to certain block devices.  Maybe put 
oneadmin in the 'disk' group and grant write access on certain 
partitions on the worker nodes...


Anyway, since this is a one-off installation, I just used virt-manager 
to create the VM.


Thanks,
Dan
