Yes there is: mdconfig -a -t vnode -f "/path/to/dd/image/file" That will cause the file to be treated as an md device. See also man mdconfig. The output of that command is the newly created /dev/md? device node. Depending on whether you dumped the whole disk, a slice, or a partition there may be additional devices. If you dd'ed the whole disk your former root partition might show up as /dev/md0s1a, for example. Once you've identified the device node(s) that contain(s) the filesystem(s) you're interested in, just mount it/them like you would any other device, e.g. mount /dev/md0s1a /mnt JN ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
Mounting/examining dd image?
I was trying to transplant my system from a small, old drive to a big, new one. I made a dd dump of the entire small drive, but then I accidentally destroyed the drive (be careful with bare drives and metal PC cases...) Anyway, I have the dd file but I don't have a spare drive onto which to copy it. Is there a way to read its contents/mount it/explore it/hopefully extract files from it on a running system? -jsd- ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
