They used to !!!! After chasing many red herrings I discovered a simple cp /tmp/file /global/dir where /global is an nfs4 mount does not work consistently 1. If the user does have permission to create the file It usually fails saying it cannot create the file because of permission problems However it creates a zero length file, with a variety of permissions set as seen above. However it sometimes copies the file correctly !!!! This was observed on one particular occasion with Thunar where some of the thumbnails were created and some not. 2. If the user does not have permission to create the file No problem - no zero length file created 3. Root works too, the file is copied OK and belongs to root:root Switching back to nfs3 mounts avoids the problems and all is well ------------------------------------------------------------- Has anyone seen anything similar? Has anyone any suggestions as to where my nfs4 configuration could be wrong ? The two lines used nfs3/nfs4 are shown below (I use NIS to distribute the files) maui.jaa.org.uk ~ 6# cat /etc/auto.home * -fstype=nfs 148.197.29.5:/exports/home/& #* -fstype=nfs4,rsize=32768,wsize=32768 148.197.29.5:/home/& maui.jaa.org.uk ~ 7# cat /etc/auto.direct /global -fstype=nfs 148.197.29.5:/exports/global #/global -fstype=nfs4,rsize=32768,wsize=32768 148.197.29.5:/global Should I create a bug report ??
