Does the cp actually complete? As in, does it copy all of the blocks? What’s the exit code?
A cp’d file should have “new” metadata. That is, it should have it’s own dates, owners, etc. (not necessarily copied from the source file). I ran ‘strace cp foo1 foo2’, and it was pretty instructive, maybe that would get you more info. On CentOS strace is in it’s own package, YMMV. -- Stephen > On Feb 3, 2017, at 8:19 AM, Andreas Mattsson <[email protected] > <mailto:[email protected]>> wrote: > > That works. > > ’touch test100’ > > Feb 3 14:16 test100 > > ‘cp test100 test101’ > > Feb 3 14:16 test100 > Apr 21 2027 test101 > > ‘touch –r test100 test101’ > > Feb 3 14:16 test100 > Feb 3 14:16 test101 > > /Andreas > > > That’s a cool one. :) > > What if you use the "random date" file as a time reference to touch another > file (like, 'touch -r file02 file03’)? > > -- > Stephen > > > > On Feb 3, 2017, at 7:46 AM, Andreas Mattsson <[email protected] > <mailto:[email protected]>> wrote: > > 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 > The NFS clients are up to date Centos and Debian machines. > All Scale servers and NFS clients have correct date and time via NTP. > > Creating a file, for instance ‘touch file00’, gives correct timestamp. > Moving the file, ‘mv file00 file01’, gives correct timestamp > 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. > > This is only via NFS.
