Problems unpacking Stage3 tarball

[darthlunchbox]

Hello all, I've been using Ubuntu for a few years now and finally decided to make the switch to something more intense. I'm trying to dual-boot Gentoo with Windows 7 on a newly built computer. I've been following the installation documentation on Gentoo's site, but I keep encountering a problem.

First a quick background: I got to the end of the install already, but I had mistyped my grub configuration file, so I tried to go back through the livecd and edit it. Only, when I remounted everything and chrooted, there was no grub/boot folder. After a while, I just decided to start the install fresh and formatted the partition with ext3 again. Now, everything seems to go well until I try to unpack the stage3 tarball. It bombs out and gives me some errors:

# tar xjpf stage3-i686-20100824.tar.bz2
tar: ./boot/.keep: Cannot open: Read-only file system
tar: ./boot/boot: Cannot create symlink to '.': File exists
tar: ./boot: Cannot utime: Read-only file system
tar: ./boot: Cannot change ownershipt to uid 0, gid 0: Read-only file system
tar: ./boot: Cannot change mode to rwxr-xr-x: Read-only file system
tar: Exiting with failure status due to previous errors.

I think these have to do with the previous almost-install I had accomplished, but I'm not sure of that, and wouldn't know how to fix that if it is the case.

If anyone's got an idea, it would be greatly appreciated!

EDIT:
Here's the machine specs (for what it's worth):
Intel i7-930
EVGA x58 FTW3 motherboard
nvidia geforce gtx 480

It looks as if you are trying to unpack the tarball in your cdrom root partition. Have you mounted the new ext3 partition on /mnt/gentoo and moved across to it?

I've mounted /dev/sda3 (my linux partition formatted to ext3) to /mnt/gentoo, and also mounted /dev/sda1 to /mnt/gentoo/boot, then changed my directory to /mnt/gentoo (sda2 is my windows partition), but I'm still getting those errors. :/ Did I mess up a command in there?

Have you used chroot at this point? Are you installing from another Linux install or LiveCD?

[Segfault]

mount command will display what's mounted and where. Filesystems with errors are mounted read-only by default.

It looks like he's using a CD. And as far as I can remember from my own Gentoo install, you can't chroot until you've unpacked the tarball because, before that, there aren't the files to make a working root partition.

If Segfault is right, then the answer might be to run fsck on the new partition and correct any filesystem errors before proceeding further.

I am running of the liveCD right now; should have mentioned that. But anyway, when I run the 'mount' comman, sans any other input, I get quite a few lines, but my hard drives are listed last as such:

/dev/sda3 on /mnt/gentoo type ext3 (rw)
/dev/sda1 on /mnt/gentoo/boot type ntfs (rw)

The only devices listed as read-only are /dev/sr0 and /dev/loop0, which is mounted on /mnt/livecd.

When I run fsck /dev/sda3, it outputs this:

fsck from util-linux-ng 2.17.2
e2fsck 1.41.11 (14-Mar-2010)
/dev/sda3: recovering journal
/dev/sda3: clean, 36267/30228480 files, 2113718/120906552 blocks

I mounted the MBR and linux partition again, but the same errors come out of unpacking the tarball.

sda1 is NTFS? Is this your Windows partition?
Your / is supposed to be empty before downloading and unpacking stage3.

Good catch, it's also supposed to be either ext2/3/4, anything but NTFS.

I had a sneaking suspicion that had something to do with it, but I wasn't sure. That's the boot sector on the hard drive, so I should mke2fs on /sda1 and it should be good? (I don't want to accidentally kill something, so I'm making sure I'm keeping up with you guys first )
