This evening I added a 36 GB drive to our department server. I did a

the new drive got added twice, but with different UUIDs. Of course


is no way vgchange will bring it online. Is there a solution to the
problem? I downloaded LDE from <http://lde.sourceforge.net/> to have a
look at it, but I don't know what to alter. I run Slackware 8 with


2.4.8 and LVM-1.0. The attached files contain output from pvdata -U -V


on all three partitions.

You're right sdb1 appears to have been added twice with seperate
UUID's.  I'm at a loss to explain this at the moment.  Did you run
pvcreate more than once on sdb1 ? (I want to know where that extra
uuid came from).

Well here's the full story: I added the new disk, made a new LVM partition, ran pvcreate on it. Did a vgextend vg1 /dev/sdb1. Rebooted. No vg:s found, Panic: root not found. Spent a bunch of hours hackaing a Slackware 8 boot floppy with LVM 1.0 support. It found the vg. Next idea: Maybe it's because of devfs. I hacked the disk a bit further yo use devfs, and now it didn't find the VG:s. I started looking for any LVM list archive, found something about small initrd:s so I put an 8 MB initrd image on the root floppy, and wow, the VG was there. Tried to put a larger initrd on the boot partition and re-ran lilo. Rebooted, no success. Later I realised that a initrd_size=8912k might have done the trick. Booted from the floppy again and did a vgreduce vg1 /dev/sdb1. Now it would boot. Here I should really have backed up everything to a non LVM partition, but instead I did a vgextend vg1 sdb1. Re-ran lvmcreate_initrd, re-ran lilo and rebooted. That's where I am now. Two SDB1:s with separate UUID's. Can this be fixed or should I format and reinstall? It would really feel bad because I've never had to format and reinstall a Linux system except for the occasional hardware failure.
