Hi,we recognized this behavior when we tried to move HSM migrated files between filesets. This cases a recall. Very annoying when the data are afterword stored on the same pools and have to be migrated back to tape.
@IBM: should we open a RFE to address this?

Is this still true if the source and target fileset are both in the same storage pool? It seems like they could just move the metadata… Especially in the case of dependent filesets where the metadata is actually in the same allocation area for both the source and target.Maybe this just doesn’t happen often enough to optimize? -- StephenOn Apr 16, 2020, at 12:50 PM, Oesterlin, Robert <[email protected] <mailto:[email protected]>> wrote:Moving data between filesets is like moving files between file systems. Normally when you move files between directories, it’s simple metadata, but with filesets (dependent or independent) is a full copy and delete of the old data.Bob Oesterlin Sr Principal Storage Engineer, Nuance*From:*<[email protected] <mailto:[email protected]>> on behalf of "J.

Dependent on the root fileset. Anyhow a user wants to move a large amount of data from one fileset to another. Would this be a metadata only operation? He has attempted to small amount of data and has noticed some thrasing._______________________________________________ gpfsug-discuss mailing list gpfsug-discuss atspectrumscale.org <http://spectrumscale.org/> http://gpfsug.org/mailman/listinfo/gpfsug-discuss_______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at spectrumscale.org http://gpfsug.org/mailman/listinfo/gpfsug-discuss
