Hi, below you can find requested information from OpenStack DB. There is no issue right now, but maybe historical tracking could list to some hint? Anyway, issue was related with /dev/vdb drive for instance: 128f1398-a7c5-48f8-8bbc-a132e3e2d556 -> in DB output you can observe that size of volume is 15GB, when directly from instance it was reported as 115GB(so vdb of second instance presented in this output) mysql> select * from block_device_mapping where instance_uuid = '90fda439-fc0e-4e22-8d0b-6f2a18eeb9c1';
