The /pfs mounting command may not be entered into /etc/fstab after an upgrade. A good indication of this is that after the upgrade is complete, you cannot start capture again. If you log in to the command line interface and run 'df -h', you'll notice that /pfs is not mounted.
This should match /etc/solera/config/capture-config
ls -l /dev/disk/by-id | grep sdc or often it is sdc1
You will see something like:
Put the results from the ls-l above to look like:
scsi-36d4ae520a554d40018926ec005b37c46-part1 /pfs dsfs nosuid 0 2
Then reboot to bring up the appliance properly.
