It is showing less than 300 G because it is a sparse file. (all the blocks are not allocated upfront.)
The difference on the NFS server *may* be because of the BUG mentioned in the man page. " On BSD systems, `du' reports sizes that are half the correct values for files that are NFS-mounted from HP-UX systems. On HP-UX systems, it reports sizes that are twice the correct values for files that are NFS-mounted from BSD systems. This is due to a flaw in HP-UX; it also affects the HP-UX `du' program." /Jd --- On Thu, 1/15/09, Brian Krusic <br...@krusic.com> wrote: > From: Brian Krusic <br...@krusic.com> > Subject: [convirt-users] unexpected image sizes > To: xenman-users@lists.sourceforge.net > Date: Thursday, January 15, 2009, 3:05 PM > Hi all, > > So I shutdown my domU to copy it to a backup location (yes, > I am still > trying to find a way to do a live backup/snapshot so if > anyone has > suggestions, I would love to hear). > > So, du -h /var/lib/xen/images/host.img > > ... shows 18G > > So I copy it to my NFS mounted backup machine and upon > doing a du -h / > nfs-share/backups/host.img > > ... show 7.6G. > > This domU is actually set to have 300G but I didn't > allocate all of > the disk space during domU creation. > > Any ideas?
