<p class="MsoNormal"><span lang="EN-GB">I’m having some really strange timestamp behaviour when doing file operations on NFS mounts shared via CES on spectrum scale 4.2.1.1
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The NFS clients are up to date Centos and Debian machines.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">All Scale servers and NFS clients have correct date and time via NTP.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Creating a file, for instance ‘touch file00’, gives correct timestamp.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Moving the file, ‘mv file00 file01’, gives correct timestamp<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Copying the file, ‘cp file01 file02’, gives a random timestamp anywhere in time, for instance Oct 12 2095 or Feb 29 1976 or something similar.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">This is only via NFS. Copying the file via a native gpfs-mount or via SMB gives a correct timestamp.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Doing the same operation over NFS to other NFS-servers works correct, it is only when operating on the NFS-share from the Spectrum Scale CES the issue occurs.<o:p></o:p></span></p>
