CLOUDSTACK-9466: Fix fk constraint failure in upgrade path
In the 4.1.0-4.2.0 db upgrade path, it creates new tables to store secondary
(nfs) storage in image_store table and volumes in volume_store_ref table. In
the upgrade path, it first tries to migrate NFS storage pool where it
excludes
storage pools which have been removed, but it migrates all the volumes
without
checking if their storage pools have been removed. This causes fk constraint
failure as the volume/row being inserted refers to a storage pool which does
not exist in the image_store table.
The fix migrates all the nfs storage pools to image_store including removed
storage pools and in doing so migrates with the 'removed' field. This fixes
db upgrade for old pre-4.0 and 4.0/4.1 CloudStack clouds.
