 <font size="1">While since long there was permanent lack of space on t3 home server (t3nfs01, ~7TB),
                        the way to resolve the problem  is to  migrate to a new home location on PSI standard nfs facility /t3home.<br/>
                        /t3home is mounted  already on UIs and WNs since June 2018 in addition to current /shome  and  is in use by test users and newcomers.<br/>
                        The  new default quota is 10GB to  keep scripts, documentation, stuff like this.<br/>
                        It's configured currently with 1 daily, 1 weekly and 1 monthly snapshots (on a specially reserved PSI nfs backup volume).<br/>
                        In spite of the big gap in quota sizes current movement is easy: all user data  from   /shome  is still FULLY AVAILABLE and usable.<br/>
                        The next  possible step is to re-use current backup space (t3nfs02, ~20TB). One might append it to /shome  and use combined volume (7+20 = 27TB) as a "scratch" for big size data.
