ok...
my bad. there is an additional step that has to be done tha t i left out. my apologies. once you've found that you do have the lvms with the: lvm pvscan lvm vgscan lvm lvscan
cmds... the lvm(s) might be in an inactive state. if you do a "ls /dev" and you see that you have "/dev/VolGroup00" or something to that effect depending on how you named your lvms... you're ok. if not, then you simply need to activate the lvms by doing: lvm vgchange -ay
this will go ahaead and set the lvm(s) to an active state, where it will then show up under the "/dev" dir...
the rest of the steps i provided should work ok..
thanks..
Hi...
Ran into an interesting issue during the past week, and figured I'd post the issue, and solution here in case it might come in handy for someone else...
The laptop was running, but it was left on with the lid closed for a day or so.. when powered up, the laptop went into a state saying it couldn't find the mounts... hmm.. shouldn't have thought this could happen. figured the drive might screwing up, so i reinstalled FC8.
after a few hours, got everything back.. went and plugged the laptop into a power strip that had a short..!! ouch, saw the same behavior.. got sort of nervous, but thought it should be ok (hopefully!) so after another reinstall, got to really wondering what was really going on... didn't think about it.. the laptop was working.. things were cool.. for a day! and after closing the lid, and then reopening.. after another day or so. saw the same behavior.
here's what i was seeing:
Filesystemtype is ext2fs, partition type 0x83
"VolGroup00" using etadata type lvm2 2 logical volumes in volume group "VolGroup00" now active
VFS: Can't find ext3 filesystem on dev dm-3 mount: error mounting /dev/root on /sysroot as ext3: Invalid argument setuproot: moving /dev failed: No such file or directory setuproot: error mounting /proc: No such file or directory setuproot: error mounting /sys: No such file or directory switchroot: mount failed: No such file or directory
========================================
at this point, talked to a few people, and started thinking that somehow the disk was getting, had gotten corrupted.
so...
started to try to see what the drive had, if anything!
poped in the FC8 rescuedCD, and went to work..
ran the cmds: lvm pvscan lvm vgscan lvm lvscan
since i had installed using the defaults for FC8 LVM, the drive showed that it was basically ok.
went ahead and ran fdisk /dev/sda and saw that i indeed had my two partitions /dev/sda1, /dev/sda2
so at this point..
i did a mkdir /dev/sysimage, followed by a mount /dev/VolGroup00/LogVol00 /mnt/sysimage
this worked, and got me to a point where i could hopefully fix/repair whatever errs might be on the drive...
i then ran e2fsck -y /dev/VolGroup00/LogVol00
after a little hope.. and an amount of time as the system did it's thing, it came back saying how many sectors where corrected, etc...
i then rebooted, and the laptop was back up/running as it should!
feel free to add to this if you have useful information, or additional insight that you want to share.
peace.
