Not sure if I get these, also. Have to take a closer look on next reboot.
So, do you ahve any idea how to capture all the boot messages so I can
report back accurately?
Hmm, didn't try this, but you could put tee into your initrd and append

Now I tried :-). Don't do this on the /sbin/devfsd line. If you let the
mkinitrd script _create_ linuxrc, the use \${LOGFILE}. You could also add
-v options to evms_activate, modprobe and mount to have more details in
your logfile.

Hey, that was/is a real helper. Althugh I was out of time for the whole day,
after returning back, saw your email, downloaded initrd from the site, and
all the old messages disappeared, although there are some new like:
device-mapper: 3.0.0-ioctl (2003-03-28) initialised: [EMAIL PROTECTED]
device-mapper: ioctl interface mismatch: kernel(3.0.0), user(4.0.0), cmd(0)
device-mapper: unknown block ioctl 0x5310
Maybe it's because I have evms2.1.0, while initrd uses 2.1.1?
Anyway, for now I'm satisfied with the outcome of trying devs initrd.
Since I'm too tired to look at the new messages now, I'm going to investigate
them tomorrow.
Thank you for the pointer.
My script (if you still use it), doesn't copy /etc/{passwd,group} to the
initrd, so user/group name resolution does not work from it.
Thank you for the info. Creating initrd by hand also did not resolve this
issue with user/groups.
Sincerely,
Gour

As you can see from my other post, using EVMS devs initrd gets rid of them.
After modifying my linuxrc to get a logfile and carefully watching boot
output, all I can say is I don't get these. Please ask on the evms-devel
mailinglist.
They are no longet present, but I'll probably ask regarding the newly
appeared messages :-)

Re: [gentoo-user] EVMS2 on root partition
My initrd (bzip2 -9) is available at [sent privately] - it's only hosted on 56k, be nice :) Also, if you can get the kernel's output from when it fails to mount your root partition and post it to the list, it'd be of great assistance. Enabling CONFIG_SERIAL_CONSOLE in your kernel and booting with console=ttyS0 will dump the startup messages on the serial port, which you can capture with another machine. Chris PS.
