    FreeBSD disklabel problem

    Can someone please help me figure out how to change disklabel in freebsd 4.8. I am using the old version as it is required by the software i want to run. I am installing Olive emulator so that i can create a virtual juniper router. I have googled this for 2 days now and no joy i tried repartitiong drive but it did not work. This is what i am trying to achive:

    ad0a /
    ad0b swap
    ad0e /config
    ad0f /var

    currently:

    /dev/ad4s1a /
    /dev/ad4s1h /config
    /dev/ad4s1f /tmp
    /dev/ad4s1g /usr
    /dev/ad4s1e /var

    What ever i tried to do with disklabel -e command ends in device busy i tried to umount partitions then change the disk label and it did not work i also tried booting into single user .... it did not work. Any ideas i am getting desperate

    ad0a; looks like that's a whole disk.. Normally it would be ad0s1a. The s1 denotes the first slice (aka dos partition).

    Do I read it correctly and your current setup is using ad4s1 as the slice for fbsd? And you want to change it to ad0?

    ad0 is the master drive on the first IDE port
    ad1 is the slave on the first IDE port
    ad2 is the master on the secondary IDE port
    ad3 is the slave on the secondary IDE port

    ad4 is either USB or perhaps S-ATA drive?

    Doesn't matter though.. The software should install anyway and doesn't need to look at the devices itself, it'll only 'see' the directory structure and that looks alright..

    Doesn't the installation work? Does it complain? Or are you following some tutorial that gave the partitioning schema?

    Ok this is correct ad4s1a. Here is the link for Junos setup on Freebsd:

    http://juniper.cluepon.net/index.php/Olive

    Now when i run a package itself it complains as i think it does not know where to install it. The error i get:

    sysctl: unknown oid 'hw.re.model'

    You could try removing the options ATA_STATIC_ID from the kernel config and recompile.

    Then it would count the first drive as 0, second 1 etc. regardless of where it's connected.
    Mind you, if you add/remove a cd/dvd rom or another HD the numbers may shift..


    Another option would be to manually edit the install script and replace all ad0 with ad4 (search&replace)..
