Hi Mark, > Yet another reason not to have your root file system on a logical volume.
how right you are. But we used the default installation setup and I don't really know if and how I can change this LogVol Setup afterwards. kind regards Anna -----Original Message----- From: Linux on 390 Port on behalf of Mark Post *EXTERN* Sent: Thu 3/27/2008 6:50 PM To: [email protected] Subject: Re: modprobe.conf >>> On Thu, Mar 27, 2008 at 1:16 PM, in message <[EMAIL PROTECTED]>, Fuhrmann Anna <[EMAIL PROTECTED]> wrote: -snip- > Next thing I thought of was: I forgot about modprobe conf.

If you add a "dasd=####" parameter to /etc/zipl.conf and build your special initrd, you should be OK. One way to check is to: cd /tmp mkdir initrd.test cd initrd.test zcat /boot/initrd > initrd.nogz cpio -iv < initrd.nogz and look at the contents of the init file that gets unloaded. -snip- > PS > Why I am afraid of the "semi-official" clone method: > mounting the DASD where I copied the system and wanting to change > configuration files this way > may be risky because the home system and the mounted system both have the > very same LogVol-setup. > Same setup, meaning also same names/labels.
