@pepsov, @phillxnet will likely be able to provide more targeted guidance on what to investigate where, but you could have a look at this thread, starting around here that goes into detail about the udev usage and disk ids:
lots of it is probably not applicable to your situation, as that thread deals with an HP server setup, but you might be able to extract some details that can help you overcome this situation.
I don’t believe, that the 4.x version of Rockstor will make any difference here, but of course, if we there is a permanent fix to be had, it would only be released in that latest development.
