I think that the worst of the worst has happened. I was looking at logical volume groups in webmin and tried to make a new one, from my /dev/hdb2 partition. I started the process and noticed at the bottome "all data will be lost" and quickly stopped the process. I then halted the system, connected my FC3 drive, booted, and kept my fingers crossed. Kernel panic. No linux partions found. I can see with fdisk -l /dev/hdb that the partitions are still there, and partition 2 is an lvm volume, but how to access it now. That was all my stuff, everything that I had saved! <sob!> Looks like I am commited now to FC5 and have no choice but to move ahead. I did try to rename the FC3 lvm to VolGroup01 instead of VolGroup00 like it was and got a device busy result. Now when I go back into webmin and check logical volume managment, I can see two volume groups, 00 and 01 and 01 is on /dev/hdb2, my old FC3 install! I see that there is one physical volume present, /dev/hdb2 and it is 190Gb in size, that is it, my FC3 install. But over in the Logical Volumes, the group has no logical volumes yet. I know that the volume is there, I just screwed it up but how to get it back? I really, really need this badly and am afraid to lose it altogether. There has to be a way to recover this logical volume somehow, at least it has a different volume group now, 01 instead of the 00 that the current system resides on. Oh man somebody help. Bit, where can I post for help with this? Are there any good newsgroups for linux volume group recovery? -- ~Ohmster theohmster at comcast dot net Put "messageforohmster" in message body to pass my spam filter.

First thing you should do is before upgrade is backup important stuff first. $ Tar -xzcf ~/lessthan_DVDsize.tar.gz /abunchofdirectoriesunder4gig K3b ~/lessthan_DVDsize.tar.gz files to a couple of DVD-RWs Second do not panic. With FC3 as the primary system, boot from the FC5 DVD boot: linux rescue # you get the prompt $ chroot /mnt/sysimage $ ls ~ # you should still see your data If you can see your data then you can disconnect the FC3 and reinstall FC5 without the LVM. Like I said go through the manual create partition menu and delete the Logical Volume partitioning. Then you should at least have one partition for / Then complete the FC5 installation. After that completes you should be able to reconnect the FC3 drive $ mount -t ext3 /dev/hdb1 /mnt/fc3sys $ cp -a /mnt/fc3sys/home/Ohmster /home $ cp -a /mnt/fc3sys/usr/(directories not already on FC5) /usr After you've cp'd all the data to the FC5 system My FC5 installation wouldn't create a swap partition but it's ok you don't need one and you can dd a swapfile, mkswap and swapon if you need one later. Like LVM nice but not necessary for low user systems. I'd disconnect the FC3 drive, reboot to make sure the FC5 has everything and works properly. Then you can do what you want with the FC3 drive and even "dread" install LVM on both drives. As soon as I figure out how to install my second hd in this pc without removing the cpu fan, I plan to use LVM. I think using Webmin instead of commandline LVM commands you inadvertently ran pvcreate on hdb1 which I mentioned you should not do. Perhaps I should have said never run LVM create anything on hdb?

No can do. When I try that, the rescue disc scans for Fedora installations and does not find any, therefore it does not mount any. Examining the logical volume group with the xwindows LVM tool shows that it is present on /dev/hdb2, which is correct, and it has a different name now, VolGroup01. The physical view shows 189Gb of space which is correct. The logical view shows all of that space as free. Now I know that all my files are still there, the darned thing did not run long enough to erase all of the files, but something happened to the logical drive and now all the space is marked as "Free" with no files present. Bummer. I gotta find some way to bring them back. -- ~Ohmster theohmster at comcast dot net Put "messageforohmster" in message body to pass my spam filter. |
