Unusual IDE device names
 

I just installed Fedora 4 on a box with a new motherboard and chip. I used one of my spare 10 GB IDE drives to install Linux on. I then added a 40 GB IDE drive that had a FAT32 partition and a ext3 partition (20 GB each). I was hoping to get access to the ext3 partition but was not counting on it. Then I was going to format the entire drive to ext3.

When I added the drive to my system and booted up linux, the kernel said it was scanning all volumes and has renamed my 10 GB hard drive from hda to VolGroup00-LogVol00 in /dev/mapper and has named my 40 GB drive to VolGroup00-LogVol01 in /dev/mapper. Looking at dsemg it appears that the 40 GB drive is corrupt and probably the cause of the hard drive device name changes.

If I reformat the 40 GB drive will it revert back to a normal naming convention or do I need to take additional steps?

Thanks,
Herman Radtke

The Fedora 4 default install creates 2 partitions (your hda1, hda2) /boot and a LVM partition ( labeled VolGroup00-LogVol00)that contains / and swap. Your 40GB drive also appears to have a LVM partition which was named VolGroup00-LogVol01. There appear to be 4+ partitons but due do errors I can not tell if there are any logical partitions. Any partition not LVM can be accessed like /dev/hdc1. Without seeing how the drives are actually partitioned this appears to be normal.

The hard drive error could be due to a drive issue with the intel chipset but most likely it is an indication that it is going bad.

The install is brand new. If I installed Fedora 4 again and manually created my partitions, as opposed to druid, I could get around this?

Yes, BTW LVM stands for logical volume managent. You can google for more info but in a nutshell it allows one to expand storage capacity by adding drives easily.

I have a similar problem. Fedora 4, ATA/100 PCI card, 46GB Maxtor with similar errors. I have data I'd like to recover. I also have ATA/133 PCI card with two other drives which are configured under LVM. I'm confident if I get the ATA/100 - 46GB combo working, I can get my data off and then I can rebuild that machine without the problem some 46G drive.
