allows users to perform operations specific to the Coda File
System. Most often, people use it to see how much of their
allocated storage space they are currently using and to
change the protection on their personal directories.
cfs will change the protection or "rights"
on directories but not on individual files. To change
permissions on individual files, use chmod(1).
Use ‘strong’ to override adaptation to changing network conditions. Revert to automatic adaptation using ‘adaptive’. This command is useful to force strong connectivity semantics even over slow or unreliable links.
Checkpoint volume modify log. This command will create a checkpoint file /usr/coda/spool/uid/vol@mountpt. Where uid is your local user id, vol is the volume being checkpointed, and mountpt is the volume’s mount point.
Check the status of the Coda file servers. Report on servers that are down.
Check volume/name mappings.
Clear short-term priorities used for cache management.
When the end of a pathname component in a symlink is either @sys or @cpu, the local venus will replace these magic strings with a platform dependent string. These cfs commands can be used to check what the precise expansion values depending on the current OS/cpu.
Tell venus to expand a conflict. The dangling symlink becomes a directory that contains readonly copies of all the versions of the object as found on the various replicas.
Tell venus to end a repair session on file. Useful if repair is exits without finishing the repair session.
Examine reintegration closure. Using cfs examineclosure will display the fixfile used to reintegrate changes that were made while operating in disconnected mode.
Flush entire cache. Care must be taken when using the cfs flushcache command, as flushing the cache while operating in disconnected mode may result in loss of data.
Flush objects from cache. cfs flushobject tells venus to remove the given objects from the cache.
Flush all data in specified volumes. Care must be taken when using the cfs flushvolume command, as flushing the cache while operating in disconnected mode may result in loss of data.
Map the given paths to Coda file ids.
Map fid to volume-relative path. cfs getpath will display the path for each of the given fids.
List access control list for each of the given directories.
List the contents of the entire cache or the given volumes (directories).
Display the current status of the volume in which the directory is stored.
List the countents of a mount point. This command can be used to tell what volume a mount point refers to.
Create a mount point. Mount volume name at the point in the file system described by filename. If the volume name is not specified, venus will try to mount a volume named based on the path from the top of the realm to the mountpoint. For instance, cfs mkmount /coda/coda.cs.cmu.edu/new will attempt to mount a volume named /new.
Purge volume modify log. Care must be taken when using the cfs purgeml command, as it may result in loss of data.
Replay reintegration closure.
Remove a mount point from the file system. The volume itself is not changed.
Set access control list. Sets the access control list for each id. The -clear switch clears the access control list except for the entries given on the call to cfs. The -negative switch denies the given permissions, rather than granting them. Rights are a subset of rwidlak which are read, write, insert, delete, lookup, administer, and lock respectively. See the section on File Protection in the Coda File System Users and System Administrators Manual for more detail.
Truncate the RVM log at this instant.
Tells venus whether it should wait forever for dead file servers or not. By default, venus does not wait; it returns ETIMEDOUT. For certain batch jobs, waiting is better than not waiting.
List the servers that the given files reside on.
Partition your client from the Coda file servers.
Reconnect to the Coda file servers. cfs reconnect will undo the effects of a cfs disconnect.
Tell venus to write disconnect on the given volumes, or all volumes if none are provided. Write disconnected operation will fetch files from the server, but does not propagate changes back immediately.
An -age argument gives the age of the CML before it should be reintegrated. The -time arguments gives the number of seconds the sending of a reintegration fragment should take.
Strongly connect to the servers.
