Upgrade Note

This is taken straight out of the release notes, and its definately something you should be aware of, at upgrade time.....

"The MARS Appliance performs a file system consistency check (fsck) on all disks when either of the following conditions is met:

•If the system has not been rebooted during the past 180 days.

•If the system has been rebooted 30 times.

The fsck operation takes a long time to complete, which can result in significant unplanned downtime when rebooting the system after meeting a condition above.

For example, a MARS 50 appliance can take up to 90 minutes to perform the operation.

We also saw this behaviour weeks ago... was a kind of suprise we the device seems down and we pluged some remote console / display in. But seems quite obvious to have a fsck on regular basis.
