Hi Howard Your start point is "man lvreduce". Depending of the filesystem type you're using you would have to find out how to resize the FS _before_ using lvreduce/lvextend. Depending on the FS type it may or may not be possible to do it on a mounted FS. In worst case a boot from Rescue-CD would be necessary == down-time. You will have to do this: resize (decrease size of) the file system on the huge_lvol lvreduce huge_lvol lvextend tight_lvol resize (increase size of) the file system on the tight_lvol LVols resizing was I think the first and most important motivation to write LVM. Good luck. Regards, Chris On Wed, Aug 31, 2005 at 02:56:40PM -0500, Meadows, Howard T wrote: > > I have a volume group with 4 logical volumes.
