partial upgrade or update /home/user not found anymore on software raid0 partition
I have Ubuntu Studio Lucid 64 (pre-empt kernel) on a software raid 0 partition (md0). My /home is supposed to be on another raid 0 partition (md1).
I believe that in my tiredness I may have ran a partial upgrade which didn't succeed in loading the latest kernel -30, so I am still on -28.
I couldn't boot into my system anymore, so I tried recovery, and chose to repair broken pkgs, (also apt-get clean since I also had a message that my /boot partition was 100% full- which is ok now).
What I can do at this point is to boot into a blank desktop with no access to programs or my files etc....
ERROR:could not update ICEauthority file /home/user.ICEauthority
nautilus could not create the following required folders
pls. create therse folders or set the permissions such that nautilus can create them.
I worked from TTY console or recovery console and attempted various recommended chown but get message that/home/usr is not found:
"/home/user" "file does not exist"
lists swap files only no / or /home ...Is this normal? If not how can I still be accessing / then? Other Ubuntu versions on same and other computers seem to have / and /home partitions in fstab. Could a partial upgrade that didn't get fully installed mess up fstab?
From terminal and cding to /home and typing:
shows 2 lines with permissions etc ending in .
but NO lines showing lost+found
here's an example of a working OS also on a md0 partition on another computer:
user@computer:/home$ ls -la
drwxr-xr-x 4 root root 4096 2008-10-25 07:13 .
drwxr-xr-x 22 root root 4096 2011-04-05 12:48 ..
drwx------ 2 root root 16384 2008-10-25 06:38 lost+found
drwxr-xr-x 69 user user 4096 2011-04-15 21:16 user
Some posts suggest to remove and re-install nautilus but I beleive I need to fix /home first...For all I know it may have been just a partial update-I was so tired. I did a couple of other things that had changed the permissions, but I didn't rm anything for certain!
Are my home contents lost?
Pls. re-installating the whole distribution is NOT an option and re-installing home will be tricky with software raid....any solutions???
Sorry, finished work today and now promised hubby to watch a movie on the computer in question, cause I have been at it for a couple of days (note: my generic non-raid Ubuntu boots fine)... ASAP afterwards, I will post it, check /proc/partitions and /proc/mounts and use DU disk utility as someone mentionned. Pls. bear with me, in case I have to reconstuct my software raid0, as I have never done anything like this, and don't want to mess things up furthur. I am worried since my multi drive/ OS set up was such a headache to get done, partly cause my MB had a quirk or 2, which I discovered only once 1/2 my OS were installed!
ok back...hope you'll get to see this, bhaslinux...
I was attempting to photograph my screen with the results, from my webcam on a long USB cable, but that was a fool's errand. Nope, I don't have a digital camera yet...
Looks like /home is missing from cat /proc/mounts! Its still listed by blkid, mdadm --detail/dev/md1, cat/proc/partitions, and cat /proc/mdstat. I'll try to list some details but that has to be it. Now the only problem is that blkid and sudo mdadm --detail/dev/md1 give different UUIDs for the raid partitions. Maybe it doesn't matter. I want to use nano and try to add the md1 device to cat /proc/mounts, but maybe I'll wait a little for a confirmation just to make sure...
/dev/md1: label "U Studio L Home" UUID:63626aef-46d0-49cc-83ei-7810029217d2 Type
I double checked and everything seems to correspond to the right /dev; for example my / is md0 and is around 45 Gigs total thus confirms that md1 is /home. BTW when if I changed permissions for a partition/directory and have a label like my /home above, without the _ between the words (U_Studio_L_Home) can this cause a problem? It seems to matter if I want it to be seen as a directory, correct?
Let me know if more info is needed!

bhaslinux, I have some good news! Before I had a chance to see these instructions to add to /proc/mount, I kept trying to add /home to fstab with nano. I had tried using the UUID, /dev/md1 /home ext4 defaults 0 0 and /dev/md1 /home ext4 relatime 0 0 and finally /dev/md1 /home ext4 defaults 0 2. And it only worked until a second reboot, which at that point, I didn't expect it to!
As soon as I was back with /home/my username and nautilus working again, the message with /boot being full 100% came up so I followed instructions and checked my linux-images in synaptic: It confirmed that last kernel had installed in /boot but failed due to dependancies:
I then I removed linux-image-2.6.32-30 & 2.6.32-21 & 2.6.32-25 pre-empt kernels (I marked the latter 2 for complete removal) and did:
Now everything works fine as before!!
I will keep note how to add lines in /proc/mounts for any future problems, because I wasen't using the right format so it gave me "invalid arguement". I will add more details if needed for anyone else who may run into a similar problem...
