Move veritas filesystem space between Logical volumes

Steelysteel · #1 (**permalink**) 11-24-2008

I have a veritas file system (fsA) that is nearing capacity. We have secondary file system (fsB). that is unused and would like to move some of it's disk space but I'm unsure as to how to do this with.

/dev/vx/dsk/vg05/lvol05
25288704 21887258 3188911 88% /fsA
/dev/vx/dsk/vg05/lvol04
256000000 152953 239856631 1% /fsB

I know how to grow the file system using the command:
vxresize -F vxfs -g vg05 lvol05 +2G

But how would I allocate 40GB from lvol04 to lvol05?
I'm a veritas/filesystem newb.

The easiest way is to use vxresize to shrink the second volume (eg use -2g to shrink by 2GB ), then vxresize the one you want to grow.

Thanks Reborg. Worked perfectly. As I read your post, I realized that the logical volumes were in the same volume group so a shrink/increase would be trivial. Brain fart for me.

I was thinking that the the LV's were in separate volume groups which, I presume, complicates the matter. Correct? if so, what would I have to do differently?
