Hi Emmanuel, Mount shows the following options which resulted from "defaults,_netdev" in fstab: rus4iws.rus.uni-stuttgart.de:/vol/rus4iws_data0/ on /home type nfs4 (rw,relatime,vers=4.0,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=129.69.98.101,local_lock=none,addr=129.69.201.103,_netdev) I now also tried with "noac" and without _netdev (where I forgot its meaning .. I think it was a recommendation to cirumvent some systemd boot problem) like the following: rus4iws.rus.uni-stuttgart.de:/vol/rus4iws_data0/ on /home type nfs4 (rw,relatime,sync,vers=4.0,rsize=65536,wsize=65536,namlen=255,acregmin=0,acregmax=0,acdirmin=0,acdirmax=0,hard,noac,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=129.69.98.101,local_lock=none,addr=129.69.201.103) But it did not resolve anything.
