Can't get thru "init"

Post by JoeHenley » Sat Jul 28, 2012 9:04 pm

Hi,

I'm trying to install MM 0.25.0-81b5 using PXElinux NFS boot via a server running Fedora Core 16 and Myth 0.25 (from atrpms ver 286).

I can get past the dhcp part, then screen goes blank for a few seconds. Then I get error messages ending in a "panic." It appears to be running in /tftpboot/minimyth-0.25.0-81b5/sbin/init when it occurs. The first few error messages are:
mount: none has wrong device number or fs type unionfs not supported
mkdir: can't create directory 'initrd'; read only file system
pivot-root: No such file or directory
mkdir: can't create directory '/etc/'; read only file system
Then I get a few more messages and then the panic and the trace.

Any thoughts or suggestions appreciated. Thanks!

Could you try with the latest MiniMyth version (81)?

How much memory for the initrd is allocated on the boot line (ramdisk_size=?)?
MiniMyth running on an Acer ApireRevo 3610 and a Zotac ZBOX-ID80-U. Find out more at my MythTV page.

Hi Pablo,

Thanks for the quick response!

Ummm, I don't have a ramdisk_size parameter on my boot line. My pxelinux.cfg file has:
--------------------------- snip --------------------------------
DEFAULT minimyth-nfs
NOESCAPE 1
DISPLAY messages
# TIMEOUT 5
LABEL minimyth-nfs
KERNEL minimyth-0.25.0-81b5/kernel
APPEND ro root=/dev/nfs ip=dhcp nfsroot=192.168.1.200:/tftpboot/minimyth-0.25.0-81b5 pci=nomsi hpet=disable i8042.noaux
------------------------ sni -------------------------------
The FE has 2 GB memory.
Could you try with the latest MiniMyth version (81)?
Certainly. I'm running MythTV ver 0.25 (atrpms sub ver 286) in the BE. I can't recall the "rule" on MythTV BE/FE database versions, will 0.25 BE be OK with 0.25.2 FE?

Thanks!

Hi Pablo,

I dug around and it looked like it was OK to run a 0.25.2 BE against a 0.25 FE. So I gave it a shot; I loaded MM ver 0.25.2-81.

As before, it got past the dhcp part (and I think it gets past loading pxelinux), then the screen went blank, then a few seconds later it paniced. But the message is abit different:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown block (2,0)
PID: 1, Comm: swapper/0 Not tainted 3.4.6 #1
Call Trace: yada yada

Thoughts, suggestions?

Thanks again for all your help!

Hi all,

My bad. Turns out that this problem stems from a typo on my part. Once I discovered and corrected it, the problem went away. Sorry for the false alarm.
