I find that cloudstack needs to mount subdirectory of primary or secondary storage NFS. For example,if I use 192.168.1.10:/secondary as my secondary storage,cloudstack will not only mount /secondary,but also mount /secondary/template/tpml/1/3 sometimes. Now I have a storage device which does not support subdirectory mounting,so if cloudstack use it as its primary/secondary storage,the system vms can not start. I want to know how to deal with the problem.
