DESCRIPTION
cfs 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).

bandwidth
    Provide a hint about network speed. Use this command to tell venus your networks speed in bits per second. Abbreviation: bw.

checkpointml
    Checkpoint volume modify log. This command will create a checkpoint file /usr/coda/spool/<uid>/<vol>@<mountpt>. Where <uid> is your cfs user id, <vol> is the volume being checkpointed, and <mountpt> is the volume's mount point. Abbreviation: ck.

checkservers
    Check the status of the Coda file servers. Report on servers that are down.

checkvolumes
    Check volume/name mappings.

clearpriorities
    Clear short-term priorities used for cache management.

compress
    Compress given files in the cache. These files will be uncompressed automatically if they are touched or can be explicitely uncompressed with the cfs uncompress command.

disconnect
    Partition your client from the Coda file servers.

endrepair
    Tell venus to end a repair session on file. Useful if repair is exits without finishing the repair session. Abbreviation: er.

examineclosure
    Examine reintegration closure. Using cfs examineclosure will display the fixfile used to reintegrate changes that were made while operating in disconnected mode. Abbreviation: ec

flushcache
    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.

flushobject
    Flush objects from cache. cfs flushobject tells venus to remove the given objects from the cache. Abbreviation: fl

flushvolume
    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.

getfid
    Map the given paths to Coda file ids. Abbreviation: gf

getpath
    Map fid to volume-relative path. cfs getpath will display the path for each of the given fids. Abbreviation: gp

listacl
    List access control list for each of the given directories. Abbreviation: la

listcache
    List the contents of the entire cache or the given volumes (directories). Abbreviation: lc

listvol
    Display the current status of the volume in which the directory is stored. Abbreviation: lv

lsmount
    List the countents of a mount point. This command can be used to tell what volume a mount point refers to.

mkmount
    Create a mount point. Mount volume name at the point in the file system described by filename. If the -rw flag is set, never use the corresponding read-only volume for a volume. Otherwise, if a read-only volume exists (and the parent is also a read-only volume), use the read-only volume. Abbreviation: mkm

purgeml
    Purge volume modify log. Care must be taken when using the cfs purgeml command, as it may result in loss of data.

reconnect
    Reconnect to the Coda file servers. cfs reconnect will undo the effects of a cfs disconnect.

replayclosure
    Replay reintegration closure. Abbreviation: rc

rmmount
    Remove a mount point from the file system. The volume itself is not changed. Abbreviation: rmm

setacl
    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 manual for more detail. Abbreviation: sa

slow
    Set network speed to the given speed in bits per second.

truncatelog
    Truncate the RVM log at this instant. Abbreviation: tl

uncompress
    Uncompress given cached files. venus will automatically uncompress any compressed files that it touches in the cache.

waitforever
    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. Abbreviation: wf

whereis
    List the servers that the given files reside on.

writedisconnect
    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. Abbreviation: wd

writereconnect
    Strongly connect to the servers. Abbreviation: wr
