hello everyone. i tried to install 2.6.17.4 on my box. everything works well with 2.4. i want an upgrade and update. i'm using lvm. i installed lvm2 from source and also compiled the device-mapper and also patched the kernel (2.6.17.4). At first i tried to boot without the initrd ramdisk and it gave me that it "VFS: Cannot open root device "mapper/<lv-device>" or unknown-block(0,0)" I tryied to make a ramdisk initrd image with the script lvmcreate_initrd for the 2.6.17.4 kernel and put it together with the kernel bzImage. After that i tried to boot and it gave me that it mounts the initrd image but it dosn't find the vgscan and the vgchange which are located on /sbin in the initrd filesystem. After that i mounted the ramdisk on my working kernel 2.4 system and everything seemed to be in place. the files were in /sbin and linuxrc contained the exact paths. I can't understand what i'm doing wrong. Please help!
I forgot to mention that I installed the raid components including the device-mapper support in 2.6.

Thanks in advance!
