@dannyboy1121 Just a quick update:
As of Rockstor testing channel update version 3.8-14.22 the potential problem with the next stable release with your very long nutanix serial numbers and consequent by-id names should no longer exist as the GitHub issue opened as a result of this forum thread has now been closed. This fix should end up in the next stable release so my previous concerns over your long device names in the current testing channel updates and consequently the next stable channel update no longer apply.
Hope that helps: (bit by bit).
