So one of my partitions filled up too soon :-). It's on a 4 TB drive, and I figured I'd shrink the time machine backup on the same disk to make more room.
Except that I found that the partition layout put the time machine partition at the front of the drive, and the data partition at the end of the drive. So my first thought was to look at core storage and logical volumes. The thinking was to turn the existing data partition into a logical volume, and then add a second logical volume to it -- resizing the data without having to copy it. I can't find anything in diskutil's man page to describe how to add a new physical volume to a logical volume. A "workable" (but slow) solution is to just delete the TM (3 tb), put a copy of the data at the front of the drive, and make a new smaller TM at the end. That would work, but copying a full TB of data on the same spindle is slow. (Not a big deal, just an annoyance). My question is: What can be done with core storage? How can you add new physical volumes to existing partitions? Perhaps more usefully / generally: Lets say you had a large, 4 TB drive that you knew you were going to have different data stored on. You break it up into 8 1/2 TB partitions. You want to be able to expand two different logical volumes/partitions as needed, not knowing ahead of time which one would need how much of the space. How would something like this be done with core storage, or is this not what core storage is intended for? (10.9.5, in case that matters). --- Entertaining minecraft videos http://YouTube.com/keybounce _______________________________________________ MacOSX-talk mailing list MacOSX-talk@omnigroup.com http://www.omnigroup.com/mailman/listinfo/macosx-talk
