 Posted: Fri Apr 21, 2006 6:02 pm Post subject: How to make initrd? |
 |
|
Hello. I recompiled kernel (from gentoo sources), installed it and get error: "Unable to mount your root fs...". This is because of I use ReiserFS: the system doesn't reconize it. I know that one answer to this problem is to make initial ram disk (initrd). I tryed | Code: | | mkinitrd -c -k kernel-version reiserfs |
In Slackware it works, but in Gentoo doesn't. So, can anybody tell me how to make initrd?
Thanks. |

Gentoo sources have reiserfs patches. Check your kernel config. You can use genkernel to create initrd. What error do you get with mkinitrd?

Edit: You may want to post your /etc/fstab here as that could be the problem. |

With mkinitrd I get message that command not found.
This is error I get when I try to boot up with new kernel:
| Code: | UDF-fs: No partition found (1)
XFS: bad magic number
XFS: SB validate failed
Kernel panic - not syncing: VFS: unable to mount root fs on unknow-block(1,0) |
My fstab: | Code: |
/dev/hdc /mnt/cdrom auto noauto,owner,ro 0 0
/dev/hda6 none swap sw 0 0
/dev/hda7 / reiserfs defaults 0 1 #Gentoo
/dev/hda8 none swap sw 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/hda5 /mnt/hda5 reiserfs defaults 0 0 #Slackware
/dev/hda1 /mnt/ntfs ntfs defaults 0 0 #Windows

And my grub.conf: | Code: |

| maybe something like "emerge -av reiserfsprogs" (or reiser4progs?) is needed? |

I made initial ram disk, but I still get kernel panic.
I also have build in ReiserFS support as driver, not module. Perhaps I should compile it as module? |

maybe you dont have the right sata controller or ide driver installed? I usually make sure my root partitions filesystem driver is compiled into the kernel and not as a module.
