My inexperience on installs really demonstrated<br>I managed to completely fubar my main fc5 on sda1<br>using an f10 live/install cd<br>I was able to recover w a backup fc5copy....see below<br><br>summary of f10liveinstall from memory, not sure of all steps<br>
--the livecd itself saw usb as sda? just like knoppix?<br>--it had a confusing double menu for choice of disk<br> --on 2nd half i clicked on sdc6 (ie sdb6)<br> --but on 1st half it rqrd something to click sda,b, or c<br>
-- i may well have left this as sdb(ie sda)?<br>--then its response listed something re LVM<br> and a separate /boot partn?, evidently no choice<br><br>-- i tried to back out before any changes commited,<br> did it twice or more, <br>
could easily have made mistake/confused installer<br><br>then viewing system from knoppix cd<br>(here seen from reboot into my backup fc5copy)<br>[root@bootp ~]# df -kh<br>Filesystem Size Used Avail Use% Mounted on<br>
/dev/sdb6 7.7G 5.6G 1.8G 77% /<br>tmpfs 1014M 0 1014M 0% /dev/shm<br>/dev/sda1 190M 5.6M 175M 4% /mnt/sda1 <<only 190M???<br>[root@bootp ~]# pwd<br>nothing in sda1 except lost+found, <br>
my entire orig sda1 my mainfc5 wiped out<br><br>at some point after this<br>i did the mbr reinstall as per kyle rankin apr09LJ <br> using dd and my mbrbackup on usb<br>then fdisk -l looked normal<br>[root@bootp ~]# fdisk -l<br>
<br>Disk /dev/sda: 36.7 GB, 36703934464 bytes<br>255 heads, 63 sectors/track, 4462 cylinders<br>Units = cylinders of 16065 * 512 = 8225280 bytes<br><br> Device Boot Start End Blocks Id System<br>/dev/sda1 * 1 2676 21494938+ 83 Linux<br>
/dev/sda2 2677 3163 3911827+ 82 Linux swap / Solaris<br>/dev/sda3 3164 4462 10434217+ 83 Linux<br><br>21G size for sda1<br>but the df results say only 190M, a strong indication fubard.<br>
<br>i finally was able to boot into my fc5copy on sdb6<br>by first installing into mbr of sda<br>in knoppix cd <br> root (hd1,5)<br> setup (hd0)<br><br>(this didnt work if usbexternal connected, seen as sda in knoppix<br>
then: root (hd2,5) setup (hd1) did say succeeded <br> but trying to boot wo knoppix ends w GRUB GRUB GRUB GRUB <br>)<br><br>my questions re liveinstall cd<br>--i was trying to use _only_ sdb6, (which i backed out of)<br>
but livecd also did something evidently wiping sda1<br> do i need to have available more than one partition for livecd?<br><br>--livecd seems to leave no choice by LVM-- can i choose no LVM?<br>--maybe livecd also trying to setup separate boot partn, not sure.<br>
again, can i choose no LVM?<br><br>--re my apparently fubared sda1: just reformat? or no need?<br> can i reuse it for other stuff? what size is it?<br> I dont understand how <br>fdisk shows sda size 21G but df has 190M??????<br>
<br>all in all this was very frustrating, but<br>--at least i have a working fc5 with <br> only a few months of data files gone bc not backed up<br>--before i finally recovered my fc5 copy on sdb6<br> i learned i could chroot to it off of the knoppixcd;<br>
this was useful, took notes running emacs in that chroot.<br>--i did get practice using my mbrbackup <br> and also practice knoppixcd to recover (did i need both?)<br><br>question re knoppix cd (i know, this is OT for fedoralist)<br>
-- this is a purchased cd,<br> it appears limited, comes up as "microknoppix"<br> eg neither gpart nor gparted available<br>--are there more complete versions? <br> --the f10 liveinstall cd now has me scared off,<br>
but in its liveonly aspects does it have gparted, gpart?<br><br>comments, advice all appreciated<br>Jack<br><br><br>
