RE: [linux-lvm] Moving Xen LV to image and mounting the image.

Just trying to see the partitions incase I have to mount with an offset.

I installed the xfs module with yum and then deleted all the loopback devices with losetup -d and started over again...

[root wdcxen1 ~]# losetup -a
[root wdcxen1 ~]# losetup /dev/loop0 /root/wdcdns1.img
[root wdcxen1 ~]# losetup -a
/dev/loop0: [0807]:14876937 (/root/wdcdns1.img)
[root wdcxen1 ~]# mount -t xfs -o loop,ro,noatime,nodev,nofsck ~/wdcdns1.img /mnt/tmp/
mount: wrong fs type, bad option, bad superblock on /dev/loop1,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

I really appreciate everyones help, this has been stumping me for a week or so.

Thanks!
