You should give LVM2 a try on some test system please. It supports the LVM1 metadata (IOW: you can install it and use your volume groups created with LVM1). The only major feature missing in LVM2 is 'pvmove' which we are working on right now. > > Any pointers to documentation would be appreciated. Meanwhile, I'm busy > Googling ... LVM2 is command line compatible with LVM1. The new features are (mostly) in the man pages comming with the LVN2 source distro. You need to get device-mapper from our website as well (see the usual README/INSTALL files). > > -- Dossy > > -- > Dossy Shiobara mail: dossy@panoptic.com > Panoptic Computer Network web: http://www.panoptic.com/ > "He realized the fastest way to change is to laugh at your own > folly -- then you can let go and quickly move on."
