    Default [SOLVED] Disk Usage Stats Issue

    I hope that the Disk Usage graphs on my system are not correct.

    We are running FOSS GA 5.0.0 on Ubuntu 6.06.

    Two 250 GB HD in software raid using reiserfs.

    Modified zmdisklog as indicated below:

    Code:
    if ($platform =~ /MACOSX/) {
    	$MNTCMD = "mount -t hfs";
    	$DFCMD = "df -ml ";
    } else {
    #shm20080103	$MNTCMD = "mount -t ext3";
    	$MNTCMD = "mount -t reiserfs";	#shm20080103
    	$DFCMD = "df -mlP ";
    }
    df yields the following (I know I could have done a better job with partitioning):
    Code:
    Filesystem           1K-blocks      Used Available Use% Mounted on
    /dev/md0             234228428  16202780 218025648   7% /
    varrun                 2076196        40   2076156   1% /var/run
    varlock                2076196         4   2076192   1% /var/lock
    udev                   2076196        80   2076116   1% /dev
    devshm                 2076196         0   2076196   0% /dev/shm
    A screen shot of Disk_Usage graph is attached.

    Can someone explain why Disk_Usages shows more than half my capacity used while df indicates we have used only 7% of our disk space?

    Thanks in advance!

    If you look at the green as the drive size = 230k
    & blue as the space available = 218k
    The key is the minimum shown on that graph = 200k
    I believe this bug was meant to address it: Bug 17303 - disk stats graph should use "0" to "Total Size" for the "Y-axis"

    Thanks for pointing the scale out. You'd think an engineer (me) would have been smart enough to figure that out. Sorry!
