 Posted: Mon Sep 17, 2012 2:50 pm Post subject: grub missing from boot (vmware) |
 |
|
after upgrading the kernel, I get error (awk:fatal) about grub.conf and it asks me to create it manually.
genkernel works fine on its own:
http://pastebin.com/KCwTKgEh
However, I want the genkernel to automatically update my grub boot loader configuration but it fails (may be because it can not find grub).
http://pastebin.com/cU1MR8dU
this is odd but I dont have the grub configuration file:
| Code: |
~ # nano /boot/
System.map-genkernel-x86-3.3.8-gentoo initramfs-genkernel-x86-3.3.8-gentoo kernel-genkernel-x86-3.3.8-gentoo
~ # locate grub.conf
/usr/portage/sys-boot/grub/files/grub.conf.gentoo
/usr/share/doc/grub-0.97-r10/grub.conf.gentoo.bz2
/usr/share/doc/grub-0.97-r10/grub.conf.sample.bz2
|
More info:
| Code: |
~ # cd /boot/
System.map-genkernel-x86-3.3.8-gentoo initramfs-genkernel-x86-3.3.8-gentoo kernel-genkernel-x86-3.3.8-gentoo
~ # locate grub.conf
/usr/portage/sys-boot/grub/files/grub.conf.gentoo
/usr/share/doc/grub-0.97-r10/grub.conf.gentoo.bz2
/usr/share/doc/grub-0.97-r10/grub.conf.sample.bz2
~ # cd /lib/modules/
2.6.25-hardened-r13/ 2.6.28-hardened-r6/ 2.6.28-hardened-r7/ 2.6.28-hardened-r9/ 3.3.8-gentoo/
~ # cd /usr/src/
.keep linux/ linux-2.6.28-hardened-r7/ linux-2.6.28-hardened-r9/ linux-3.3.8-gentoo/
|
How to resolve this? Can I manually create a grub.conf file and add the kernel in it?

More info on grub:

These are the packages that would be merged, in order:

Probably. Or else grub was never installed to the boot partition. Can't really tell.
@nitish.anand, genkernel has an option called MOUNTBOOT that you will find in /etc/genkernel.conf that will take care of mounting the boot partition for you.

Ah. Arg, you're right.
@nitish.anand, one possibility is that your new kernel doesn't include filesystem support for the filesystem used on the boot partition. Normally a genkernel-generated kernel will include support for most common filesystems, though. Have you been modifying the configuration heavily with the genkernel --menuconfig option? If so, you should do so again and check that you have support for the boot partition filesystem.
Wait, is XFS really your boot partition filesystem? Probably not as I don't believe grub supports XFS. An incorrect /etc/fstab could be why /boot isn't mounting.

thx John and jaglover for your prompt responses. Yes this was a kernel upgrade from 2.6.36 hardened -r9 to 3.3.8
after emerging the gentoo-sources, I ran genkernel --menuconfig --bootloader=grub all.
In the menuconfig, the only thing I changed was Virtualization (changed from M to *). Thinking * will include the support for vmware.

This has reportedly since been fixed, and the 0.97 version (at least) of GRUB is apparently stable.
http://xfs.org/index.php/XFS_FAQ#Q:_Does_GRUB_work_with_XFS.3F
@Jaglover - no idea why my current kernel (linux-2.6.28-hardened-r9) cant find boot. I have not rebooted into the new kernel after upgrading to 3.3.8, could this be the cause? I am not sure of reboot as it might fail after.

Fibbing doesn't help. Unless your system is seriously nonstandard, none of the commands you show above except the one I recommended produces the output you posted. Are you running in a chroot right now?

Sorry; that's beyond my area of expertise. What do you think that tells you?
Looking at your "lspci -n" output, the driver for the virtual hard drive controller is a standard (although somewhat old) Intel ICH IDE controller. The device driver that handles it is | Code: | -> Device Drivers
-> Serial ATA and Parallel ATA drivers (ATA [=y])
-> ATA SFF support (ATA_SFF [=y])
-> ATA BMDMA support (ATA_BMDMA [=y])
-> Intel ESB, ICH, PIIX3, PIIX4 PATA/SATA support |
however I believe that the out of the box genkernel configuration should have support for that. You could reboot your virtual machine into the install CD (that is how you installed this, right?) enter the chroot, and then run | Code: | | genkernel --menuconfig all |
to see whether or not it's enabled (probably as a module). Note that you must properly set up grub to lave the initramfs available to properly boot a genkernel kernel image.
However, that all said, I've never see a system act like yours it: booted up but with the device nodes not existing the for root filesystem device. Perhaps someone with more virtualization experience will chime in.

John, I believe it booted up using legacy IDE drivers, udev will not create nodes for hd* but the way rootfs is mounted at boot still gives access to the root filesystem.
@nitish.anand
You should disable IDE support in kernel and enable PATA driver as John suggested.

Interesting. Would've though that the legacy drivers would've been long gone from the genkernel-supplied kernel config files. Definitely worth checking, though.

thx John and jaglover, this server was hosted on a separate hardware before and was imported into virtual environment (converted as vm) in 2010 (by my predecessor).
I tried rebooting my server last night with lots of problems (boot not found obviously and then modprobe.conf issues). So I have reverted back to earlier snapshot and gone back to kernel 2.6.28 (where sync + system + world + revdep works and the server reboots fine) - it is a bodge fix until I retry upgrading the kernel to 3.3.8. But I thought to first solve this 'boot not seen by kernel' issue before upgrading.
