After installing it, I decided to try out LVM. I created a group using 4 harddrives (using entire disk, no partitioning), set up a volume, and formatted it with reiserfs.
Actually I started with 1 volume on the empty drive, moved the data from a full drive over, prepped and added that drive etc.
Unfortunately, Mandrake sucks so bad that it fragged the menus on all desktops when I tried to run the system update, leaving me with no shell access and such.
I did the ctrl-alt-f8 to get to a console shell and copied my /etc directory to another drive, then proceeded to reinstall the OS (approximately 40 times before I figured out the magical incantations necessary to make it not blow up in my face).
Note that the OS iteself was not on an LVM (hda is a normal, partitioned disk). The LVM group is on hde, hdi, hdj, and hdk.
Now that I have Mandrake behaving itself (sort of), I want to mount the LVM group again. Unfortunately I can't seem to get Linux to mount it without complaining about not being able to reach a certain sector =(
I activated the group, did a vgscan and pvscan which created the /dev entries and some /etc entries, but if I try to mount it (/dev/group1/vol1), it sits there and does nothing (I waited 40 minutes before giving up).
If I run fsck.reiserfs on it, it sits busy for about 5-10 minutes and then complains about not being able to reach a sector (along with a suggestion that my disk has an error on it).

The problem has occurred looks like a hardware problem. If you have bad blocks, we advise you to get a new hard drive, because once you get one bad block that the disk drive internals cannot hide from your sight, the chances of getting more are generally said to become much higher (precise statistics are unknown to us), and this disk drive is probably not expensive enough for you to risk your time and data on it. If you don't want to follow that advice, then if you have just a few bad blocks, try writing to the bad blocks and see if the drive remaps the bad blocks (that means it takes a block it has in reserve and allocates it for use for requests of that block number). If it cannot remap the block, this could be quite bad, as it may mean that so many blocks have gone bad that none remain in reserve to allocate.
bread: Cannot read the block (44171264): (Input/output error).
