<pre wrap="">Greetings --
My computer has a single hard disk drive -- but many partitions. A
couple of those partitions are dedicated to openSUSE 10.2, and the
rest are Kubuntu Jaunty (also known as Version 9.04).
In the past, I have been able to use (Jaunty) Dolphin to view all
partitions -- which meant I could copy files from one distro to the
other. I no longer SEEM to have that option. Although I see how
to modify the default start-up folder, I see nothing that would
seem to help me restore the cross-partition view. So I am blind!!!
Can anyone point out the obvious to me? THANKS for your time with
this message!!!

Hello, Anne --
FIRST, Thank you for a quick and helpful reply.
SECOND, a part of my delay in replying is due to problems that I created
for myself in the process of trying to install a VHS-DVD
player-recorder to use the "TV-AV" aspect of my computer monitor! I am
now back to normal. MEANWHILE, I have been researching the issue that
you have raised for me. I am certain that the answer to your question
is "No." But I am not at all sure quite what I need to do!
When I try to edit /etc/fstab in openSUSE, I see
/dev/sda2 / / acl,user_xattr 1 1
/dev/sda3 /home /home acl,user_xattr 1 2
/dev/sda1 swap swap defaults 0 0
proc /proc /proc defaults 0 0
sysfs /sys /sys noauto 0 0
debugfs /sys/kernel/debug debugfs noauto 0 0
usbfs /proc/bus/usb usbfs noauto 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
/dev/fd0 /media/floppy auto noauto,user,synch 0 0
The df shows
/dev/sda2 18% /
udev 1% /dev
/dev/sda3 42% /home
Both commands produce radically different output in Jaunty (9.04). Part
of this is obviously due to the partitioning which I did -- but part of
it is a combination of other variables (such as versions, etc.)! For
example, edit /etc/fstab produces a LOT of comment-code, not to
mention some really cryptic first-column device names! Trying to
minimize the confusion, let me present its output as follows. (If the
names are important, I will gladly supply them!)
proc /proc proc 0 0
/dev/sda6 / ext3 0 1
/dev/sda11 /home ext3 0 2
/dev/sda10 /opt ext3 0 2
/dev/sda7 /root ext3 0 2
/dev/sda8 /tmp ext3 0 2
/dev/sda12 /usr ext3 0 2
/dev/sda9 /var ext3 0 2
/dev/sda1 none swap 0 0
/dev/sda5 none swap 0 0
/dev/scd0 /media/cdrom0 udf,iso9660 0 0
/dev/fd0 /media/floppy auto 0 0
The first column in the preceeding listing is taken from the comments
and seems to be something from "prior to installation". The
third-from-last column is --
defaults
relatime,error=remount -ro
relatime
relatime
relatime
relatime
relatime
relatime
sw
sw
user,noauto,exec,utf8
rw,user,noauto,exec,utf8
The results of the df command are also much more extensive --
/dev/sda6 9% /
tmpfs 0% /lib/init/rw
varrun 1% /var/run
varlock 0% /var/lock
udev 1% /dev
tmpfs 1% /dev/shm
lrm 1% /lib/modules/2.6.28-11-g
eneric/volatile
/dev/sda11 2% /home
/dev/dsa10 1% /opt
/dev/sda7 4% /root
/dev/sda8 2% /tmp
/dev/sda12 10% /usr
/dev/sda9 5% /var
I really do NOT understand the fact that "tmpfs" appears TWO times above
the "eneric/volatile" entry, but I did not copy this one in error!!!
I notice that you mentioned that I should have fstab mounts for the
partitions of EACH distro in the other. This makes excellent good
sense if I am going to be moving things in both directions. I do not
anticipate doing this -- the moves will be entirely from openSUSE to
Jaunty. Can I "get away with" adding openSUSE partitions to Jaunty's
fstab -- or will things effectively blow-up in my face if I fail to
balance the equation?
THANKS for your time and assistance!!!!!

I had a similar situation.<br>
Part of the problem for you "might" be that the 2 OS'es do not use<br>
the same device names for the partitions in question. So, you will<br>
need to do some work to be sure (for example - that /dev/sdb3 in one<br>
OS is the same as /dev/sdd3 in the other os). What I am trying to<br>
point out is that the disk numbering scheme in the two OS'es might<br>
not match. So once you are able to identify the device names<br>
in both OS'es and map them 1 - 1 correctly, then adding them correctly<br>
into both OS'es fstabs should be very trivial.<br>
<br>
So, your devices on jaunty are:<br>
<br>
/dev/sda6 / ext3 0 1<br>
/dev/sda11 /home ext3 0 2<br>
/dev/sda10 /opt ext3 0 2<br>
/dev/sda7 /root ext3 0 2<br>
/dev/sda8 /tmp ext3 0 2<br>
/dev/sda12 /usr ext3 0 2<br>
/dev/sda9 /var ext3 0 2<br>
/dev/sda1 none swap 0 0<br>
/dev/sda5 none swap 0 0<br>
<br>
PS: I do not know how jaunty creates 12 partitions in a Linux disk!<br>
Jaunty seems to be using BSD partitioning scheme, no?? If that<br>
is the case, your opensuse will probably not be able to mount<br>
jaunty's non-standard Linux partitions. Standard Linux kernels<br>
simply do not write BSD partitions - even the config menu says<br>
it is dangerous to config and build the linux kernel with write<br>
support for BSD's UFS partitions.<br>
I do know that you could have for example 3 extended partitions<br>
and 4 sub-partitions in each extended partition. Perhaps that is<br>
what you did - in which case my comment re: BSD UFS does not<br>
apply.<br>
<br>
<br>
Your devices on opensuse are:<br>
/dev/sda2 / / acl,user_xattr 1 1<br>
/dev/sda3 /home /home acl,user_xattr 1 2<br>
/dev/sda1 swap swap defaults 0 0<br>
<br>
Now, which devices do you wish to be visible to both OS'es??<br>
<br>
Also, in each OS, issue the command<br>
fdisk -l /dev/sd? <br>
for all disks visible to the OS. Look in /dev to see how<br>
many sd devices there are. Save the outputs<br>
and label them so a reader will know which OS the command<br>
was run on.<br>
This will help identify which disks have same partitioning scheme<br>
and partition types, ..etc.<br>
<br>
Cheers,<br>
<br>
