Full Root Partition - now missing /hda1 - Mandriva 2006 2007
Hello,
I thought it wise to back-up my drive before upgrading from Mandriva 2006 to 2007 - wrong move. I meant to put the back-up on my CD, but somehow I ended up filling my root partition, hda1. In trying to figure out what to do, I ran across this old post and tried the following command: du -x / | sort -nr | less http://www.linuxquestions.org/questi...ight=hda6+full When I used df -a before executing the above command, I received: /dev /hda1 5.86 100% /hda6 69G 81% Afterwards I received: Filesystem Size Used Avail Use % Mounted On none 0 0 0 - /proc none 0 0 0 - /sys /dev/hda6 69 56 13 81% /home none 0 0 0 - /proc/bus/usb What happened?!?! And how do I make sure I don't lose my valuable information on hda6? Is there a way out of this? Funny enough, during boot I can see hda1 - all full; yet it doesn't show on df -a ?? Many Thanks, Phillip |
use the cd/dvd and type rescue at the boot
go to console mode type su to become root (if not already) see that all partitions are still there fdisk -l to mount hda1 mkdir /mnt/mounted_hda1 mount /dev/hda1 /mnt/mounted_hda1 to see what is in there ls -l /mnt/mounted_hda1 the command rm is for remove you could remove whatever you want alternatively use a live cd to delete / backup whateve you want alternatively install 2007 on hda1, if you look carefully at options because hda6 is on another partition it will be kept safe |
Thank-you Emmanuel,
I followed the instructions and in the end df -a gives me: /dev/hda1 5.8G 100% / (mounted on) none /proc none /sys /dev/hda6 81% none /proc/bus/usb /dev/hda1 5.8G 100% /mnt/mounted_hda1 I'd like to remove some files, but I don't know which files I can safely remove. I did clear away the /tmp and /Games. I tried to install 2007 but I get an error about no space left on device. -Phillip |

I meant install with formating /dev/hda1. You will loose everything on hda1 be sure not to format hda6 before you could mount home mkdir /home/etcback mount /dev/hda6 /home/etcback and you can use cp -R /etc/* /home/etcback/ to at least save /etc I cannot tell you what file to delete... are you sure which partition is home? do not want a disaster here ahev you got good backuos just in case |
Thank-you Emmanuel
When I went to rescue mode I used lsparts to find this: hda1: 2.9GB hda5: 549MB (swap) hda6: 34GB Why does my hda1 now say 2.9GB instead of 5.8? I went through and tried to start again, ut same problems. I haven't tried what you suggest above, but only because I want to make a back-up of some files. Is it possible for me to burn files to a CD in such a state of disrepair? If so, how do I go about doing this? -Phillip |
My take on how I got into this mess is that I inadvertently backed-up my files onto the root partition. As a result, there must be files that are simply redundant. If I can just clear these reduntant files, then I should be able to install 2007 - something I can't do now. I think anything that I care about is on my /home in hda6. Are there generic files that I can remove in the root partition that will not ruin my day? For instance, I removed the Games files, but there were few of them and so did not clear up much space - likewise /tmp.

fact that / is full (unless there is a bug in the installer or the installer needs space before the format stage - read the 2006 to 2007 upgrade thread You are better off installing than upgrading, so the only thing to really backup from / is /etc so you have your old settings if you ever want to see what they were) the command line is ls to see files You are better of with live cd if you are going to delete things on / (visually easier maybe than command line if you are not used to it) I think this is a waste of time unless you want to be able to rerun 2006 file you can delete /var/log/* I would not like to make more suggestions surrely all these file you copied there are in a directory it is a question of searching There are commands like du, and df note that if you become root and type history you would have the old command line when that backup went wrong (if you used command line) another trick maybe would be boot with rescue chroot to /mnt/mntedhda1 urpme openoffice (I have never tried, but in theory should work) The idea is to desinstall a big package (openoffice is ~100 Mo) and then reboot system. Then 2006 should boot |
You are better off installing than upgrading,
What is the difference between an install and upgrade? I thought that install would write over files that I had on there - start from scratch kind of idea. so the only thing to really backup from / is /etc so you have your old settings if you ever want to see what they were) How do I backup /etc ? By the by, regardless of how this all turns out - though with your assistance,I am optimistic - I think it is quite remarkable the number of people you help out in these forums, kudos! -Phillip |
Live cd's are great for this.
Using an archive tool, like ark, or cli tools bzip, and compress the whole thing to one contiguous file and burn it to cd. |

but when "installing" there is also an option called upgrade that try to reuse old settings and match existing packages with new version you need to mount home 1st, assuming rescue mode mkdir /mnt/myhome mount /dev/hda6 /mnt/myhome ls -l /mnt/myhome (check hda6 is what you think it is) mkdir /home/etcback cp -R /etc/* /myhome/etcback/ ls -l /myhome/etcback/ man cp for more info If you are new to linux, unless you setup fancy things, I doubt you will ever use /etcback, but you have important things there like /etc/resolv.conf Quote:
Am not the 1st, not the last Just hope one day you help other as well Best way to learn |

PHEW!!! Ok, well, I took a bit of a chance (loss of hundreds of photos) and used my installation dvd to reformat hda1 - root partition - and then reinstalled 2006. Luckily, I still have my photos, bookmarks and all important business. I'm going to burn some cds of the above mentioned goodies, and then install 2007.
Thank-YOU Emmanuel for your help - and others. -Phillip |
