The way I''ve done it in the past is: 1. Make sure that xen domain is shut down that you are re-sizing 2. Run lvextend (you''ve already done this) 3. Run e2fsck -f [logical volume name] (i.e. /dev/domain0/lvname) 4. Run resize2fs [volume name] [new size in G of LV] (i.e. resize2fs /dev/domain0/lvname 8G 5. Start up vm. New size should be reflected now. HTH -----Original

For the special case of "100%" there is no difference. For values less than 100% with a non-empty VG, the two are quite different, e.g., (50% of VG) != (50% of the free space in VG). -- Bob

I spent the afternoon yesterday googling for answers, but had have come up blank still. What I am trying to do is resize the file system to use the additional disk space that I added to the logical volume that the
