Problem: Disk Utilization graphs are not showing the correct information when one partition is not mounted. Disk utilization trend graphs are not consistant in displaying the information.

I am monitoring 3 file systems: '/', '/data, and '/backup'.

The /backup partition is only mounted while backups are actually running which only takes a few minutes. When the backup completes, the /backup drive is unmounted.

In all cases, the text (from 'df') on the web page correctly lists the partitions that are mounted and correctly displays any disk space alerts:

/data (27% used) has reached the WARNING level (25%)

Filesystem 1024-blocks Used Available Capacity Mounted on LABEL=ROOT1 8652060 3039788 5172772 38% / /dev/sda7 14740312 3753364 10238176 27% /data

When the backup partition is mounted, the disk utilization image displays all three partitions in the line graphs and lists all 3 backup' with the cur/max/min/avg data below the line graph.

When the backup partition is not mounted, the image displays only the '/' root and '/backup' partition in the line graph, and only lists '/' and '/backup' with the cur/max/min/avg data below the line graph. The '/data' partition is not displayed/listed anywhere in the image.

Looking for some suggestions as to why / how this is happening and if there is something I can do to fix this.

thanks for any suggestions/pointers, Tom
