[gpfsug-discuss] Creation time

[Michael Neumayer]

If you can use rsync (Linux) or robocopy (Windows) for the sync, preserving dates can be configured via the available options of these and similar tools. You may as well have a look at rclone (https://rclone.org/). I haven't used it a lot so far, but a colleague of mine did some large migrations with it, and was quite happy about it.

I've never tried, but if you still have the external file system available, you could probably use the mentioned tools just to update dates to their value on the source file system without transferring them again, in case you've already finished the sync.

Best,
Michael

Betreff: [gpfsug-discuss] Creation time


Is it possible to change the creation time on a file in GPFS? I have a gut feeling the answer is no and I can't see a mechanism to do so but thought I might as well ask.

The use case would be syncing in data from an external file system and preserving all those creation times, that stretch back many years rather than have them all batted down to the date of the sync.

JAB.
