Freeway Server-Resident Application (SRA) Programmer Guide
Note
Some Protogate-supplied SRA installations (such as the Monitor)
will mount the “s2g” partition as “/var” instead of “/cache”. On
these systems, the /var partition on the hard drive takes the place of
the RAM-disk partition found on standard Freeway servers.
Once you start using a disk file system mounted read-write, you can no longer just
power off the Freeway server at any time. Similar to what happens with your PC when
you just power off, you run the risk of damaging the file system on the Freeway hard
drive. Therefore, you must remember to safely shut down the operating system before
powering off the Freeway server. There is no “shutdown” selection in the Freeway menu
(there is only “reboot”), but you can shut down the operating system by logging in to
the BSD shell and typing the following command:
shutdown -p now
This command will shutdown the BSD operating system immediately, and will also
automatically power down the Freeway server as long as the ACPI function is enabled in
the server.
If you accidently power off a Freeway with a hard drive, there is a chance that some of
the file paths in the read-write partition will be damaged. The BSD operating system
will try to automatically correct the damage when the Freeway server is rebooted. As
such, the boot time may be extended while the disk is being checked. If the damage to
the file system is too great, the Freeway will fail to boot up normally. In this case, you
will need to log in as “shell” and manually check the disk using the following command:
fsck -y
Any files that are lost from a power down will be the ones in the read-write partition
(usually your data or log files), as the Freeway operating files are backed up in the read-
only partition.
