Update a port in Neutron

 

neutron port-update --fixed-ip subnet_id=SubNetID,ip_address=X.X.X.X --fixed-ip subnet_id=SubNetID,ip_address=X.X.X.X <PORT_ID>

* Don't forget to input the already present IPs in the command or they will be overwritten

 

neutron port-update PORT_UUID \
--fixed-ip=subnet_id=SUBNETID,ip_address=192.168.1.{164,165,{167..190}}\  
--fixed-ip=subnet_id=SUBNETID,ip_address=1.1.1.{164..190} \
--fixed-ip=subnet_id=SUBNETID,ip_address=10.0.0.{4..30} \  
--fixed-ip=subnet_id=SUBNETID,ip_address=172.16.1.{68..94}  

Explanation:

Line 1. replace PORT_UUID by the port ID

Line 2. Will add 192.168.1.164, 192.168.1.165, 192.168.1.167 - 192.168.1.190 (We are basically skipping 192.168.1.166)

Line 3. Will add 1.1.1.164 - 1.1.1.190

Line 4. Will add 10.0.0..4 - 10.0.0.30

Line 5. Will add 172.16.1.68 - 172.16.1.94

Stop a migraion

Remove the active volume from the migration state

find the volume in the attaching state and remove it

Adding a LVM Cinder Volume

 

mkfs.ext /dev/md0
mkdir /cinder-vol
mount /dev/md0 /cinder-volumes
dd if=/dev/zero of=/cinder-vol/cinder-vol bs=1 count=0 seek=3950G
losetup /dev/loop2 /cinder-vol/cinder-vol
pvcreate /dev/loop2
vgcreate cinder-vol /dev/loop2
