 Posted: Wed Jan 21, 2004 11:57 am Post subject: LVM problems with LiveCD [solved] |
 |
|
I've just bought a new SATA hard drive (Samsung SP1614C), which I'm trying to dual boot Win2000 and Gentoo on. The Win2000 part is done and now I'm trying to install Gentoo on the 10GB I left free, preferably using LVM. I've got an ASUS A7N8X Deluxe motherboard which has the SiI3112 SATA controller. For some reason, I couldn't get the Gentoo 1.4 LiveCD (x86-basic-1.4-20030911.iso) to boot - it chucked a spazz around 'cloop' or something. Anyway, I then tried the experimental livecd-2.6_11-29-2003.iso. This boots no problem.
However, I run into troubles when I try to set up the LVM stuff as per the guide. I can create vgcreate, but it doesn't add my volume group to /dev. Similarly I can create my logical volumes, but when I try to activate them, it fails:
| Code: |
vgchange -ay vg1
/dev/cdrom: open failed: Read-only file system
Incorrect metadata area header checksum
/dev/mapper/control: open failed: No such file or directory
Is device-mapper driver missing from kernel?
/dev/mapper/control: open failed: No such file or directory
Is device-mapper driver missing from kernel?
Incompatible libdevmapper 1.00.05-ioctl-cvs (2003-09-01)(compat) and kernel driver
0 logical volume(s) in volume group "vg1" now active
|
What's going on? Is this a problem with the LiveCD's kernel? Is there some sort of work around for this? Can anyone recommend a LiveCD that I can use?
I'm going to try using Knoppix and see if that gets me any further. My other option is to try to install from my old hard drive, but the Gentoo on that has a 2.4 kernel and I doubt it'll be able to use the new drive (if there's an easy way to fix this, let me know!). I'll keep you posted.
Any help is much appreciated.

Dude - you're trying to make your cdrom a part of a volume group.
I can only hint that this will probably not work...
Maybe read the LVM docs some more, adding your cdrom is probably not in the instructions.
Also note that getting LVM to work for the root partition is more work than just using LVM - you have to do some dark magic things. |

No kidding - at no stage did I add the cdrom to my volume group. Unless something funky is going on.
And I have separate /boot and / partitions from my LVM partition, so I ought not to need to do anything dark and magical, right? |

Hmm. could you describe what you did do to make the vg ?
ISTR that the 2.6 (lvm2) stuff works differently form what I use (lvm1); it manages the /dev entries in a sort of devfs manner, or something (sorry - not clear).
Search the forums for "asus a7n8x", it's bound to turn up (it seems a popular board). |

Exactly as in the guide.
| Code: | vgscan // whinged about /dev/cdrom
pvcreate /dev/hde7 // whinged about /dev/cdrom
vgcreate vg1 /dev/ide/host2/bus0/target0/lun0/part7 // not sure exactly what I used, but it was what /dev/hde7 pointed to. Again, whinged about /dev/cdrom.
lvcreate -L10G -nusr vg1 // gave the error in first post
|
Everything seems to have been set up fine, except I can't activate the Logical Volumes. The output of pvdisplay and lvdisplay is:
| Code: |
--- Physical volume ---
PV Name /dev/hde7
VG Name vg1
PV Size 9.50 GB / not usable 0
Allocatable yes
PE Size (KByte) 4096
Total PE 2431
Free PE 767
Allocated PE 1664
PV UUID vIWE6A-VClc-qT6K-pxpF-ipuf-AmZF-SwsgcL
--- Logical volume ---
LV Name /dev/vg1/usr
VG Name vg1
LV UUID XB2ot9-ffKY-hcka-LUnj-dt5K-qlSD-u2LR8J
LV Write Access read/write
LV Status NOT available
LV Size 3.00 GB
Current LE 768
Segments 1
Allocation next free (default)
Read ahead sectors 0

Hmmm, I know nothing about devfs. Any chance you can elaborate?

Yeah, did that before I posted. Nothing that I can find. Either not many people using LVM or they aren't having problems.
I figure the /dev/cdrom error is some artifact of running off the LiveCD. It doesn't seem to be the problem. It looks like a kernel issue. For some reason I don't have /dev/mapper and LVM doesn't like that at all. Anyone got a spare or know where I can find one?  |

| Right, I've sorted it all out and now have a working Gentoo system. First off, the reason the 1.4 LiveCD wasn't working was a dodgy download - I checked the MD5 hash and it didn't match! Anyhoo, I'd already downloaded Knoppix, so I gave that a go. I have to say - a much more pleasurable way to install! LVM worked from there, and it's all good now, except I think I need to update my partitions to LVM2, but I don't think that'll be a problem. |
