Please file a bug for this in bugzilla, fdisk should show the right data. > After "exporting" the disk to DomU the partition can't be mounted. > > mount /dev/hdc1 /test > mount: /dev/hdc1: can't read superblock > > fdisk shows the same results as in Dom0 > > fdisk -l /dev/hdc > > Disk /dev/hdc: 6999.9 GB, 6999999774720 bytes > 255 heads, 63 sectors/track, 851034 cylinders > Units = cylinders of 16065 * 512 = 8225280 bytes > > Device Boot Start End Blocks Id System > /dev/hdc1 1 48986 393479629+ 83 Linux > > but yast in DomU is not able to recognize the correct partition size. > > /dev/hdc │ 6.3 TB│ │DISK hdc │ > /dev/hdc1│ 375.2 GB│ │Linux native > > I have two questions: > > 1. why fdisk is not showing the correct partition date? > 2. is xen forwarding the partition parameters correctly? Does it work if you are not using Xen? I mean: Can you create such a file with our default x86-64 kernel?
