This version of the FS system is running all 3 of the AuScope sites. It is installed into the usual /usr2 location. The only major deviation from a standard install is the /usr2/control being a softlink to a directory /usr2/control.[hb|ke|yg].
Another relevant directory is /usr2/AuscopeUtils, which contains any AuScope code which is not reasonably stored within the control.* or st-9.10.4 directory.
This code is all stored within the “pcfs_prod” git repository on observer@ops-serv2:/home/observer/gits/pcfs_prod.git (see the section on git for more instructions).
FS Updating Procedures
Updating this code would be a matter of upgrading one site, git-adding the new fs-? and st-? directories, and git-rming the old ones after an appropriate settling period when the migration was confirmed to be successful. Obviously they could be git-rmed immediately, but this would be less convenient to roll back if problems were found.
Some care would need to be taken when migrating the contents of the new 'control' directory into the existing ones. The specific steps which will be taken will vary depending on the extent of the changes in the new FS.
FS clock errors
If the FS is complaining frequency of a formatter to FS time difference > 0.5s, it may be necessary to recalibrate the drift rate. The procedure is outlined in /usr2/fs/misc/fstime.txt. The guts of the procedure is:
