DESCRIPTIONcfs allows users to perform operations specific to the Coda File Sys‐
tem. 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).
adaptive|strong
Use `strong' to override adaptation to changing network condi‐
tions. Revert to automatic adaptation using `adaptive'. This
command is useful to force strong connectivity semantics even
over slow or unreliable links.
checkpointml
Checkpoint volume modify log. This command will create a check‐
point 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.
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.
@cpu|@sys
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.
beginrepair
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.
Abbreviation: br.
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 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.
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.
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 File System Users and System Admin‐
istrators Manual for more detail.
Abbreviation: sa
truncatelog
Truncate the RVM log at this instant.
Abbreviation: tl
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.
disconnect
Partition your client from the Coda file servers.
reconnect
Reconnect to the Coda file servers. cfs reconnect will undo the
effects of a cfs disconnect.
writedisconnect
Tell venus to write disconnect on the given volumes, or all vol‐
umes 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.
Abbreviation: wd
writereconnect
Strongly connect to the servers.
Abbreviation: wr
