 |
|
hi.
i've read (several times) all the other threads i found about this topic. but i can't yet get it to work.
my old configuration is:
| Code: | /dev/hdf1 -> /boot
/dev/hdf2 -> swap
/dev/hdf3 -> /root |
the new one should look like:
| Code: | /dev/hdf1 -> /boot (note: the /boot stays the same :p)
/dev/hdg2 -> swap
/dev/hdg3 -> /home
/dev/hdg4 -> / |
i moved the files successfully to my new harddisc. that's the way i did it:
* booted my old disk
* mounted /dev/hdg4 to /newdisk && mkdir /newdisk/home
* mounted /dev/hdg3 to /newdisk/home
* created the filesystems (reiserfs)
* copied the files | Code: | | cp -a /bin /dev /etc /home /lib /mnt /opt /root /sbin /tmp /usr /var /newdisk |
(my first attempt was but /dev didn't get copied)
* modified /newdisk/fstab to mount the new stuff
* modified /boot/grub/grub.conf, i.e. changed root=/dev/hdf3 to root=/dev/hdg4
it boots, i can start X. i got a 'unable to find a PTY' if i tried to open more than one Eterm or if i wanted to 'screen'. after some research i found out the problem was the dev filesystem wasn't mounted.
this already looks weird to me because i use the same kernel as with my old disk and it works fine there. (devfs *is* included in the kernel config). nevertheless i tried manually: and it complains about not being able to find .devfsd
but this device (?) exists in (/newdisk)/dev/.devfsd.
im pretty much clueless at the moment about what i could do now, any help is appreciated.

Not necessary - it already exists on the old one.

Not the best order - first copy /root dir, then the rest.
But it should work, all the same.

Impossible - you couldn't have mounted them without a valid filesystem!

Ridiculous - see here:
| Code: | | cp -ax /* /newdisk/ |

That's because if you use devFS it isn't part of the "normal" filesystem.
Just make a new one.

As long as you're sure that's all you changed...

Do you have devpts support in the kernel ?
It can use either devpts or the hardlinked pty's, but since your /dev seems a bit screwy, devpts is needed to make it work if the entries aren't there.

oops, right, the order was the other way around.

/dev/pts file system for Unix98 PTYs isn't checked (i assume this isn't the one you are talking about but i cannot find another entry in 'make menuconfig')
how do I check if devpts support is there?
jfyi, /newdisk/dev/pts contains 0 / 1 / 2 / 3 |

| Code: | | grep CONFIG_DEVPTS_FS /usr/src/linux/.config |
Will tell you whether it's compiled in or not.

*compiling*
[e] w00h \o/ it works now, thanks a lot!
[e2] oops, this was too early.. i can start several Eterm's (up to 4) and screen doesn't work :x
mount doesn't show any /dev mounted and devfsd /dev still not finding .devfsd :|
should i delete the contents of /dev ? will they be recreated ? |

They should be, yes - but it would be safest to make a backup, or take some other precaution.
The bootloader has been known to b0rk because of it, since devfs assigns other ide identifiers - /host/bus/target/lun, like scsi.
If you installed this way then the regular /dev/hdxy links would be made to the /ide structure, but if you cut it out after installation I wouldn't hazard any guesses...
Easiest would be to boot a liveCD, mount the root partition somewhere, and
| Code: | mv /mnt/gentoo/dev /mnt/gentoo/dev.old
mkdir /mnt/gentoo/dev
|
and reboot...
That way you can fix things easily when it b0rks.

| Code: | | Warning: Unable to open an initial console |
and it reboots automatically.
when i emptied the /dev on the newdisk as you said and reboot.
it's strange, shouldn't it just work if i do a 'cp -a /dev /newdisk/' ? (as I did previously) |

No, you always have to specify which files - otherwise it will create a dev directory inside the new /dev directory - which wouldn't work 
Instead of
| Code: | | cp -ax /dev /newdisk/dev |
do a
| Code: | | cp -ax /dev/* /newdisk/dev |
