I've got a new installation default packstack --allinone command, i tried to change the space given to all my virtual machine changing from 49Gb to what i need, but i can't find where, on dashboard i see Used 0 of 49.0GB, i've tried i can go over but i would change 40Gb limits.

i presume i'm not using cinder as storage for running virtual machine

Correct, instances do not count against the volume quota (or the "volume count" and "volume summary") numbers shown in the dashboards summary view. I'm not exactly clear what you're seeing, it sounds like you're stating that the dashboard summary shows "0 of 49GB" used? Not sure what this has to do with the hypervisor, or the comment about "change to 40". You list cinder quota-usage for the admin tenant, are you viewing summary in the dashboard as admin tenant as well?

now i've got these i give to my project quota 1000 GB (two project as test) and make some virtual machine for both project, but on the http://mydash.local/dashboard/admin/h... is see always the 98 gb limits (two node with 50 Gb x node). C:\fakepath\Screen Shot 2014-02-09 at 7.29.55 PM.png


solution:

mount a secondary disk /dev/sdb

extend /dev/xxxxx/lv_root on that disk resize (extend) lv_root on that partion

extend the ext4 filesystem on the new lvm volume reboot some service! done

command used:

dd if=/dev/zero of=/dev/sdb bs=512 count=1
pvcreate /dev/sdb 
pvscan
lvmdiskscan
pvdisplay

vgextend vg_node4 /dev/sdb 
lvextend -L+120G /dev/vg_node4/lv_root

resize2fs /dev/vg_node4/lv_root 
#e2fsck /dev/vg_node4/lv_root 
df -h
/etc/init.d/httpd stop
/etc/init.d/httpd start
/etc/init.d/memcached stop
/etc/init.d/memcached start
