Symptoms

Filesystem /var/TKLC/smac/image/isoimages on PMAC VM is full

Changes

Cause

A mount of another filesystem "/var/TKLC/smac/image/isoimages/home/smacftpusr" was mounted onto a subdirectory of "/var/TKLC/smac/image/isoimages", which hid/obscured files that were on that filesystem original file system (i.e., "/var/TKLC/smac/image/isoimages").
 
Basically, 'du' was revealing the size of the unobscured filesystem; and 'df' was showing the size of the filesystem regardless of what was obscured from the user.
So 'du' did not show the 4.6G being used

[admusr@pmacserver ~]$ sudo du -ahx /var/TKLC/smac/image/isoimages | sort -r -h | head -n 50

Solution

Fix:
umount /var/TKLC/smac/images/isoimages/home/smacftpusr
cd /var/TKLC/smac/images/isoimages/home/smacftpusr
remove unwanted files. In this case there were .iso files so we ran: rm *.iso
mount /dev/vdd /var/TKLC/smac/images/isoimages/home/smacftpusr
df and check the size of /var/TKLC/smac/image/isoimages. It should be down to 4% or less.

As a further check we also used sftp to pmacftpusr and made sure adding an image was successful.
The above fix addressed the issue.

Recommendation:
As is documented in the installation guide be sure to use sftp to pmaftpusr when adding isos to the pmac. We do not recommend using scp to /var/TKLC/smac/images/isoimages/home/smacftpusr as the pmacd user may not be able to delete the files after it adds the image.
