pvmove?

Is pmove like the "mv" command where it will move all the data from one lun to another rather than *copy* it. So LUN1 becomes empty and LUN2 has all the data after a pvmove?

Hi:

Yes. See the manpages for 'pvmove(1M)' for some options.

Whatever you do, if/when you use 'pvmove' do not interrupt (kill) it. You can leave your volume in a "corrupt" state.

Regards!

Coolmar,

From pvmove(1M):
The pvmove command moves allocated physical extents and the data they
contain from a source physical volume, source_pv_path, to one or more
other physical volumes in the same volume group.

So, yes, 'pvmove' is like 'mv' in the sense that source data are discarded after the operation completes.
