 |
|
Hi folks.
I have a amd64 box running on gentoo-sources-2.6.17-r8 with the root partition managed by evms on raided disks.
I tried updating to gentoo-sources-2.6.20-r8 but I couldn't boot that kernel, so I've reverted.
When trying to boot the new kernel I get dumped to a shell with an error message
| Code: | /linuxrc: ERROR: The root volume has not been properly mounted. Starting
/linuxrc: ERROR: a shell. Please mount the root volume manually on the
/linuxrc: ERROR: /sysroot directory. You can do this with the command:
/linuxrc: ERROR: mount -o ro /dev/evms/Your_Root_Volume /sysroot
/linuxrc: ERROR: When you exit the shell, I will attempt to continue
/linuxrc: ERROR: the boot process. |
There is no /dev/evms/, and if I cat /proc/mdstat it seems to say there are no md devices.
Any ideas why this is happening? What information can I provide to narrow things down?
To build the new kernel I simply copied my .17 config into the new .20 src dir, then make menuconfig, then exit and save, then make && make modules_install. I copied the config, kernel and system map to boot, updated grub by copying the old entry and tweaking it.
I also tried using the evms-2.5.5.initrd instead of the 2.5.4 that's working for me now.
Thanks
