 |
|
I do it follow http://gentoo-wiki.com/HOWTO_Install_Gentoo_with_NVRAID_using_dmraid
BUT, got wrong below
| Code: | livecd root # ./dmraidinitrd linuxrc initrd
Making busybox...
HOSTCC conf.o
HOSTCC zconf.tab.o
HOSTCC conf
Making device-mapper lib...
Making fake install in /tmp/initrd/opt/device-mapper...
Making dmraid...
Creating initrd image...
2048+0 records in
2048+0 records out
2097152 bytes (2.1 MB) copied, 0.018406 seconds, 114 MB/s
cp: cannot stat `/tmp/initrd/dmraid/1.0.0.rc13/tools/dmraid': No such
file or directory
Fatal error: did dmraid fail to compile?
|
And I have had make sure that libselinux has been emerged.
Does some one has the same troubles ?

orphen,
You may find this thread answers your question as it unpicks dmraid and how genkernel puts it together. The steps it goes through will be useful rather than the exact problem and solution, rather like the install handbook.
dmraid is something you should avoid if you can. Its BIOS provided software raid, so the layout of data on the drives is particular to your BIOS. the only reason to choose dmraid over kernel raid is that Windows understands dmraid too, so Windows and Linux can share the same raid set.

The problem above has been fixed.
I had changed script of dmraidinitrd to copy the dmraid in the system.
And, there is another problem.
| Code: | RAMDISK: Compressed image found at block 0
VFS: Mounted root (ext2 filesystem) readonly.
Freeing unused kernel memory: 188k freed
sh: applet not found
Kernel panic - not syncing: Attemted to kill init! |
The ash/sh can NOT be executed.
| Code: | LiveCD root# /mnt/gentoo/root/image/bin/ash
ash: applet not found
LiveCD root# /mnt/gentoo/root/image/bin/sh
sh: applet not found |
Anybody HELP?

orphen,
ash is not a vaild shell, unless you have already installed it. My system does not even have a symlink from ash to bash.
/etc/shells contains
| Code: | # /etc/shells: valid login shells
/bin/sh
/bin/bash
/bin/tcsh
/bin/csh
/bin/esh
/bin/ksh
/bin/zsh
/bin/sash |
so they should all work, even if they are symlinks to bash.
In initrds, its normal to use sh for the shell and provide it with busybox and a symbolic link.

My system does not even have a svmlink from ash to bash too.
And ash has not installed yet.
BUT, there is ash in the initrd image's /bin. And also sh in the initrd image's /bin.
The MD5SUM of ash&sh is the same.
Maybe I would to do `echo "/bin/ash" > /etc/shell` in the initrd image?
BUT, when is booting
| Code: | RAMDISK: Compressed image found at block 0
VFS: Mounted root (ext2 filesystem) readonly.
Freeing unused kernel memory: 188k freed
sh: applet not found
Kernel panic - not syncing: Attemted to kill init! |
It is "sh: applet not found!"
PS. My kernel is 2.6.18-gentoo-r3, and dmraid version is 1.0.0_rc13.

orphen,
Is /bin/busybox in the in intrd or the complete /bin/sh an /bin/ash and all the supporting libraries ?
Normally, busybox provides all the system functions an initrd needs and eveything is symlinked to it.

Thank you for your help.
The /bin/busybox is in the initrd which I have seen.
The scripts which I have used is http://gentoo-wiki.com/HOWTO_Install_Gentoo_with_NVRAID_using_dmraid/dmraidinitrd
so, I think that "all the system functions an initrd needs and eveything is symlinked to it", BUT I'm NOT sure.
