After a month of messing around with Grizzly installation, I came to the beginning - requirements.
I have Ubuntu 12.04 LTS, 64 bit, on my three machines, each with 4 gb ram, one 250 gb hard drive, one NIC.
Since I don't have another physical NIC, I added the virtual one, so that I have eth0 (for private management network, native), eth0:1 (for external public network, virtual) on my controller node. For data network it's eth0:2.
I can ping, make ssh connection with these virtual NICs, everything is the same, except that they are virtual.
With the disk I haven't done anything, I haven't created a partition for volumes, because it will erase everything on my disk.
So I just followed the steps here:
dd if=/dev/zero of=cinder-volumes bs=1 count=0 seek=2G
losetup /dev/loop2 cinder-volumes
#Type in the followings:
vgcreate cinder-volumes /dev/loop2
As I understood it created a virtual new partition but with only 1 gb, I guess, because when I type command vgdisplay I see:
--- Volume group ---
VG Name cinder-volumes
Metadata Areas 1
Metadata Sequence No 6
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 1
Open LV 1
Max PV 0
Cur PV 1
Act PV 1
VG Size 2.00 GiB
PE Size 4.00 MiB
Total PE 511
Alloc PE / Size 256 / 1.00 GiB
Free PE / Size 255 / 1020.00 MiB
VG UUID NInOD3-R3Iv-VjE6-Jk24-av3u-FlZd-7k9Gmw
Maybe I can resize it somehow, using a free space on my disk? And what about NICs? It's not how the network configuration should be?
And the last: do these two issues affect on the instance creation? It's always in ERROR state.
