[ubuntu:R1.1-10] : Subnets are still getting added ( using diff IPAM) exceeding the quota limit

[Ruchi Priya]

I had set the subnet quota to 2 for admin project,but I can add subnets >2 by using diff IPAMs through Horizon.

Only if I use the same IPAM ,I get error for exceeding the limit

Sachin,
The commit URL you pointed out is for master...is it committed to 1.10 also ?

[Ruchi Priya (ruchip)]

I observe the issue on mainline #2010 and R1.1 #25 as well:

Steps :
1) Set the quota limit for subnet to 2 ( using UI)
2) From horizon ,create a n/w and add 2 subnets using the default IPAM.
3) Try to add 3rd subnet using the default IPAM,it gives error as expected.
4) Try to add a subnet again using a new created IPAM -- test-1 ,it allows to add 1 more subnet .
5) Try to add one more subnet using IPAM -test1 --it fails
6) Add one more subnet using new IPAM test-2 ,it allows
,So it allows 1 subnet addition per new IPAM created even though the quota limit set exceeded.
