I've installing quite a bit of software into /usr lately and just noticed i was running out of space.

justin@neo justin $ df -h

/dev/hda3 2.1G 213M 1.8G 11% /

none 378M 0 378M 0% /dev/shm
/dev/sda2 14G 5.3G 8.7G 39% /mnt/ipod




Never fear, lvm2 w/ xfs to the rescue.

All while she was mounted and emergeing stuff!



No point to this post other than lvm is just good stuff.

Nice to ehar about this. I want to try it out myself, but I'll need to have ome time and search how to set it up.

OK but where did the extra 5 gig come from?

I have a 200 gb drive, 100 of it is slated for lvm and the rest just sits there and i can pull it into lvm or use it for regular partions or other distros.

One of my other systems has 4 36gb scis drives and I currently have two of them under lvm and the others aren't used, but I can bring them into my volume group if i want to add dir or expand the ones i have.
