Boot problem with FC3

System shut down normally last night.

Any and all assistance and suggestions would be appreciated


Thanks in advance to all

It might be that your physical drive containing your logical volume is not working properly.

Does your BIOS detect the drive? If not, try unplugging/replugging the drive cables (at both ends) -- they sometimes work loose, and that's the most common cause of "drive failure."

If the drive is found by your BIOS, then you'll need to try to repair it. Since it contains a logical volume, this is a non-trivial task.

CAUTION: Do not run fsck (or any variant) of the physical drive containing a logical volume partition. Doing so will destroy the logical volume. Read the logical volume information files for recovery procedures.

Boot from your FC3 CD #4 (or perhaps #5), or from your FC3 DVD, and enter "linux rescue" at the first prompt. That should boot you into "rescue" mode from the CD (after you answer a few question, which look like the instal questions).

The rescue system starts by searching all your hard drive partitions for Linux installations. It then presents you with a menu from which you can select the one you wish to "rescue" (if it finds more than one). The rescue system itself is loaded into a RAM disk, and there are several tools available for "fixing" the installation.

If it finds and mounts your logical volume, you can try fsck on the entries in /dev/mapper/, which are the images of the different file systems stored in the logical volume. If there are no entries under /dev/mapper/, then try a pvscan to see if the LV is listed as on some physical volume. If it is, start lvm and use the "help" command to list available commands. If it isn't, I'm not sure what you can do except, perhaps, download FC5 and do a new, fresh, install.

Again, I'd suggest looking for a LVM tutorial (see the button at the top of this page) before starting.

ran linux rescue and pvscan the drives show as follows:
pv../dev/sda
vg..VolGroup00

pv..unknown s/b /dev/sdb

is the problem with the second drive correctable??

can i remove the second drive from the lvm , reconnect it and then add it back to the lvm later?

thanks in advance

additional info:

lvmdiskscan:

/dev/loop0 73.67MB

/dev/sda 149.05GB
/dev/sda1 101.94MB
/dev/sda2 148.95GB LVM physical volume

/dev/sdb 149.05GB

vgscan:

couldn't find device with uuid: A4FzP4-LcHK-tBXf-NFBY-Hs4z-384s-32tX8g
couldn't find all physical volumes for VOLGROUP00
