@kimbl The issue opened in part as a result of this forum thread dev name change breaking mounts has now had another associated pull request / code change committed and is available as of Rockstor version 3.8-14.02 testing channel updates. I know this is waking an old thread that contains references to more than one issue but just by way of a heads up for anyone who wishes to test and confirm this proposed fix. As mentioned in the linked issue it is rather difficult to reproduce as it depends on specific hardware config / speed, and so is not able to be confirmed by any current Rockstor developers. @kimbl 's report in this thread looked like the closes to what has hopefully now been addressed via the now merged revise internal use and format of device names.
The referenced issue is awaiting confirmation of a fix, once one or two are received it can be closed as fixed.
