    Default Question about diskspace

    Hello all:

    Sun UltraSparc 5, running Solaris 2.5.1 with a 9G drive.

    Here is the partition table from the 'format' command:

    Part Tag Flag Cylinders Size Blocks
    0 root wm 0 - 286 132.43MB (287/0/0)
    271215
    1 swap wu 287 - 564 128.28MB (278/0/0)
    262710
    2 backup wm 0 - 8891 4.01GB (8892/0/0)
    8402940
    3 unassigned wm 565 - 8328 3.50GB (7764/0/0)
    7336980
    4 unassigned wm 8329 - 8639 143.50MB (311/0/0)
    293895
    5 unassigned wm 0 0 (0/0/0)
    0
    6 usr wm 8640 - 8891 116.28MB (252/0/0)
    238140
    7 unassigned wm 0 0 (0/0/0)
    0

    I do not understand the "backup" partition. What is it? this computer
    was shipped with the OS installed. How do I make use of that space? I
    would like to increase the / partition without reinstalling the entire
    OS.

    Thanks all.

    This suggests it is a 4Gb drive as slice 2 is normall the entire drive.

    /usr , disgustingly small will have problems with an upgrade

     
    Traditionally the whole disk, used hsitorically for the old dump command
    in SunOS4.x days. People are now paranoid over its use.
     

    Based on this info, I would suggest you backup the system.
    Boot from CD (or net)
    resize the partitons
    restore from tape.

    More info needed really for more advice
    (a df -k would be handy, how much ram and what you are doing with it)
    Also a full output from format as it appears to be a 4Gb disk and not 9Gb
    as you have stated.

    Also Also, hwta have you got against upgrading to a newer more robust
    version of Solaris ?

    It's a partition that maps to the whole disk.
     

    You already are!
     

    Reinstalling the OS is probably the easiest approach. And
    while you're at it, you might as well upgrade to Solaris 9.

    Nothing. It's my users not liking the fact that I will take down
    the DNS server with no secondary. I'm working on a secondary
    server, when that one is up and transferred all the zone files
    from this server, I will install Solaris 9 on it. What would be
    a good size for all paritions? this server will run nothing
    fancy except the latest version of BIND.

    Thank you all for your helpful suggestions.
