Hello Stackers, Our company is operating many sophisticated clusters with different storage types, such Ceph and SAN storage. What makes things trickier is that some compute node cannot use certain volume types. For example, some compute nodes do not have HBA, so they cannot take advantage of FC based SAN storage; the others do not have 10GbE ethernet, so they cannot connect to Ceph. Such deployment sometimes makes resize virtual machine quite tricky. So my question is what is best practice for this situation? Is it possible to determine if certain volume type is usable on a given compute node? Thank you very much for help. -- Best Regards, Jiatong Shen
