I realized that I made a mistake and did not leave room for doing snapshots. Now I am moving each of the LV's to a new single large logical group and leaving space for snap shots. So then I realized that I could do a "dd" to an image file (example: "dd if=/dev/VolGroup00/LogVol00 of=/root/wdcdns1.img"). I was wondering if there was a way to mount this image file? I can't seem to mount it no matter what I do. Am I doing this correctly?
I don't remember the details exactly, but I've done this before.
You tried mounting it loopback, right?
ie. mount -t xfs -o loop,ro,noatime,nodev,nofsck somesystem.img /image
If that fails, it may be because you imaged it with it mounted. If
so, you will may need to apply any outstanding journal entries to get
it to mount.
